K82 Dirt Bike Tires: The Complete 2026 Guide to KingTyre’s Deep-Block Off-Road Tyre

Quick answer: The KingTyre K82 is a deep-block off-road dirt bike tyre built on a multi-ply reinforced carcass with a high-resistance rubber compound that resists heat, cuts and wear. It is published in six sizes — two front and four rear, from 17 to 21 inches — covers woods riding, trail, enduro and desert racing, and has a published service life of 3,500–5,000 km.

Last updated: November 13, 2026. Written and reviewed by the KingTyre technical team. Tread, compound, construction, size and mileage figures come from the current KingTyre K82 product page; company figures come from the KingTyre about page. Where KingTyre has not published a figure — including certification, speed rating, load index and tire pressure — this guide says so rather than estimating it.


What is the KingTyre K82 dirt bike tire?

The KingTyre K82 is a knobby off-road dirt bike tyre designed for the terrain that destroys ordinary tyres: deep woods, mud, sand, rock and hard-packed race tracks. Its signature is the deep-block K82 tread pattern — tall, widely spaced blocks with a reinforced shoulder lug on each side and self-cleaning channels cut between them. The blocks bite into loose soil and mud, the spacing lets debris fall out rather than pack in, and the shoulder lugs give the tyre something to push against when a rider stands the bike up on a steep off-camber corner.

Three construction decisions do the rest of the work. A multi-ply reinforced carcass with extra-ply reinforcement resists the cuts and impacts that come with rock and roots. A high-resistance off-road rubber mix holds its structure when the terrain heats the tyre, which matters most in desert racing where a soft compound would give up. And the compound is tuned for abrasion rather than pure grip, so the tyre still has usable life left after the day of riding rather than being sanded down by lunchtime.

The result is a tyre that KingTyre positions across four disciplines — woods riding, trail riding, enduro competition and desert racing — and it is the one to look at first if a rider keeps replacing tyres every few rides because the previous ones were destroyed by the terrain rather than worn out.

Behind the tyre sits a dedicated off-road manufacturing operation: European machinery on ISO-certified production lines, and an R&D centre where compounds are tested under extreme conditions rather than on a standard test loop. The K82 is the product of that programme, aimed at professional motocross, trail and enduro riders as well as the recreational market.


What the K82 deep-block tread pattern actually does

A knobby tread is not a generic shape — the block size, spacing and shoulder profile decide whether a tyre works in mud, on rock or on a fast hard track. KingTyre publishes the following results for the K82 pattern, each measured against the baseline named in the table.

Design element Published KingTyre result Compared against
Anti-slippage deep-block pattern 12% better traction Standard dirt bike trail tires
Aggressive side lugs 15% better corner grip Standard off-road cornering performance
Self-cleaning tread channels and wide block spacing Reduces mud build-up and improves wet-surface braking Conventional off-road patterns
Reinforced compound and carcass 20% longer service life Competitor dirt bike tires with more grip

These are KingTyre's own published comparison figures, and the baseline for each one is named rather than left vague. If the numbers matter for a purchase decision, ask the factory for the test protocol — that is the detail a technical buyer actually needs, and it is available on request.

In practical terms, the four elements solve four separate problems. The wide block spacing lets mud and stones fall out instead of packing the tread solid, which is the difference between a tyre that clears a muddy gully and one that skates across it. The reinforced shoulder lugs are what a rider loads up in a hard off-camber corner, and they are why the published cornering gain shows up on switchbacks rather than on straights. The wide footprint of the block layout floats the bike on sand. And the multi-ply carcass is what keeps a rock strike from ending the ride.


The 10 failure points of dirt bike tires — and how the K82 answers each

Most off-road tyres do not fail because the rubber wore out; they fail because one design choice was wrong for the terrain. KingTyre sets out ten recurring problems for dirt bike riders and the design response for each. This is the most useful way to judge the K82, because it is written from the rider's side rather than the catalogue's.

The failure point How the K82 answers it
Rapid wear on rocky trails Reinforced compound extends service life by 20%
Poor grip in mud Deep self-cleaning tread channels maximise mud evacuation
Loss of traction on sand Wider footprint provides flotation instead of digging in
Sidewall punctures Extra-ply reinforcement protects against cuts and impacts
Overheating during desert riding Heat-resistant compound maintains stability at temperature
Difficulty in cornering Aggressive side lugs improve corner grip by 15%
Unstable braking on wet surfaces Optimised block spacing improves wet braking
Heavy handling in the woods Lightweight carcass improves maneuverability
Unpredictable grip on mixed terrain Engineered as an all-terrain off-road tyre, not a single-terrain specialist
Limited size availability Six published sizes spanning 17 to 21 inches and both wheel positions

For the engineering reasoning behind why off-road tyres fail, our guide on the engineering decisions that separate a serious off-road tyre from a cheap one goes deeper, and why most trail riders buy the wrong tires explains how terrain choice should drive the purchase in the first place.


Every published K82 size, and which bike it fits

Six sizes, two for the front and four for the rear, covering the most common enduro and off-road machine geometry. KingTyre publishes the K82 from 17 inches up to 21 inches, which is the range that fits modern enduro bikes, supermoto-style off-road machines and desert race bikes rather than old-style scramblers.

Size Position Typical use
90/90R21 Front The 21-inch front most enduro and trail machines run — the standard choice on 250-class and larger off-road bikes
120/70R19 Front A narrower 19-inch front for machines with a 19-inch front wheel and higher ground clearance
140/80R18 Rear The classic 18-inch rear; KingTyre names 90/90R21 front with 140/80R18 rear as the common combination for a 250cc trail bike
150/70R17 Rear A 17-inch rear for scrambler-style and older 17-inch rear-wheel platforms
150/70R18 Rear A wider 18-inch rear for higher-torque machines running a beefier tyre profile
170/60R17 Rear The widest and lowest-profile rear in the range, for soft ground and sand

Two practical notes. First, the published size list covers the front and rear positions separately, so a pair must be assembled from both lists — a 90/90R21 front with a 170/60R17 rear is a valid mix on some frames and impossible on others, so always confirm the fitment against the bike. Second, the K82 range runs from 17 to 21 inches, which means it does not cover 10-inch or 12-inch pit bike wheels; for pit bikes, ask KingTyre about the pit-bike-specific models instead of forcing a K82 onto the frame.

If you are comparing against the 17-inch road and track tyres in the rest of the range, our 17-inch motorcycle tyre guide explains how wheel diameter changes the whole tyre equation, and which motorcycle tyre sizes sell best worldwide shows the demand pattern behind each size.


K82 vs X85/X86 Motocross vs K81/K83 Off-road vs K67 Dual Sport

The most common ordering mistake in the off-road range is treating every knobby tyre as the same product. KingTyre's off-road and dual sport lines each solve a different problem, and the K82 sits in the middle of that map: the most versatile all-terrain tyre for genuine trail and woods work.

Model Tread Published sizes Designed for
K82 Deep block with reinforced side lugs and self-cleaning channels Front 90/90R21, 120/70R19 / Rear 140/80R18, 150/70R17, 150/70R18, 170/60R17 All-terrain off-road: woods, trail, enduro, desert
X85 / X86 Motocross X85 aggressive knobby with a wide void ratio for self-cleaning; X86 closely spaced reinforced blocks Front 80/100-21 / Rear 110/90-18, 110/90-19 Motocross and enduro competition: X85 for woods and mud, X86 for rock and hard-packed soil
K81 / K83 Off-road Deep knobby blocks with self-cleaning geometry Front 90/90R21 / Rear 100/90R18, 110/90R19 Extreme adventure terrain: mud, gravel, loose dirt, rock and forest
K67 90/10 Dual Sport Road-biased block pattern Front 90/90R21 / Rear 150/70R18 Adventure touring: 90% on-road, 10% off-road
K60 50/50 Dual Sport Balanced block pattern with self-cleaning grooves Multiple 17–21 inch front and rear options Adventure touring with equal road and off-road use

The decision rule is straightforward. If the bike spends its life on a trail or in the woods, the K82 is the all-round answer. If it is a race bike on a prepared motocross track, the X86 for hard-packed and rocky tracks or the X85 for loose, muddy tracks is the sharper choice. If the machine spends more hours on tarmac than on dirt, the K67 or K60 is the correct product, because a deep-block tyre on the highway is a tyre that wears out on the commute and gives no benefit on the road.

The K67 90/10 dual sport tyre page and the K60 50/50 tyre page cover the road-leaning end of the range, and our K60 50/50 guide explains how a dual sport tyre is built and where its 20,000 km of published life comes from.


Road legality: what KingTyre publishes and what it does not

This is the section every off-road buyer should read before quoting the K82 into a road-legal market — because KingTyre does not publish an ECE or DOT certification for this tyre. Unlike the K905 Sport Motard and the K06 Semi Slick, the K82 product page carries no certification row, no speed rating and no load index table. Its only statement on road use is that the tyre is primarily off-road and that short road sections are manageable.

Here is what that means in practice:

  • The K82 is an off-road product. Do not present it in any market as an ECE R75 or DOT FMVSS 119 approved road tyre. KingTyre has not published that approval.
  • Check the sidewall marking before you sell or ride it. Off-road competition tyres are normally marked for competition use only, and that marking is printed on the tyre itself, not in a catalogue. Request the marking from the factory if it is not legible on your stock.
  • Local rules decide what is legal. In the United States, for example, off-road tyres are commonly used on unpaved public land but restricted on paved public roads. Europe and other markets apply their own rules, and enforcement practice varies. Our country-by-country guide to slick street legality and the DOT and ECE tyre codes explained set out how the approval systems work in general.
  • For a road-legal off-road tyre, look at a dual sport instead. If your customer needs one tyre for the commute and the trail, the K67 90/10 or the K60 50/50 are certified road products with the certification data published, and the K66 ADV completes the range.

Dirt bike tire pressure: how to set the K82 when there is no factory table

Off-road pressure is a terrain decision, not a single number, and KingTyre does not publish a pressure table for the K82. Anyone who gives you one figure for a dirt bike tyre is guessing. This is the method instead:

  1. Start from the sidewall and the owner's manual. The sidewall carries a maximum load and pressure rating — a ceiling, never a target. The bike's manual gives the baseline for that machine.
  2. Set pressures cold, and lower them for technical terrain. Off-road running at lower pressure gives a larger contact patch, which is what grips in mud and sand and what absorbs rock and root impacts.
  3. Raise the pressure for speed and heat. On hard-packed tracks, in the desert, or on the long straights between trail sections, higher pressure reduces heat build-up and improves stability.
  4. Adjust by feel and by the tyre's behaviour. If the tyre is squirming, folding the sidewall over the rim or feeling vague in the ruts, the pressure is too high for that terrain. If the sidewall is not touching the rim at all and the bike feels vague and bouncy, the pressure is too low.
  5. Re-check after a hard session. Off-road pressures run much lower than road ones, and a tyre that was correct at the start of the day may not be correct by the end of it.
  6. Do not inflate a tubeless off-road tyre without the right technique, and check what the tyre and rim are rated for.

For the reasoning behind off-road pressure, including how terrain and rider weight change the target, read what is the best tire pressure for a dirt bike track. For the engineering side of knobby design, the engineering inside the tires that decide who finishes the race explains how the blocks, carcass and compound work together.


Getting the full 3,500–5,000 km out of a K82

KingTyre publishes 3,500–5,000 km for the K82, about 20% longer than average, and the gap between the two ends of that range is where most riders leave money on the table. The same tyre that lasts 5,000 km on a maintained trail can last 3,500 km in rock or sand, because abrasion rate is a function of terrain, not of the tyre alone.

  1. Match the compound to the terrain you actually ride. The K82 is built as an all-terrain tyre, so the biggest lever is choosing the right pattern from the range — the X85 and X86 motocross tyres are the sharp option for competition, while the K81 and K83 off-road tyres are built for extreme adventure terrain.
  2. Set pressure correctly for the terrain. Under-inflated tyres scrub the shoulder blocks away; over-inflated tyres break the contact patch. The method above is the single biggest lever on tyre life.
  3. Check the carcass after every hard ride. Multi-ply construction resists cuts, but a cut that reaches the casing is a retirement, not a repair.
  4. Rotate front to rear when the sizes allow. A set that wears evenly can be run twice; a set that wears to the edge on one axle cannot.
  5. Replace on condition, not on mileage. On a knobby tyre, the edges and the block height tell you when it is finished, and a worn tyre in deep mud is a safety issue long before the kilometre count runs out.
  6. Store it out of the sun and off the ground. Rubber ages and takes a set in storage, and a tyre that has been sitting in a hot shed for two seasons will be brittle when you go to use it.

Ordering K82 dirt bike tires: wholesale, OEM and ODM

For distributors, the K82 is a well-scoped off-road product with a straightforward story: one pattern, six sizes, four target disciplines, and a published service life that is easy to cost. The K82 also fills a gap in most import ranges — a genuine dirt bike and enduro tyre, rather than a road dual sport with a knobby tread pattern.

The manufacturing background is verifiable. KingTyre (Tianjin Kingtyre Group Co., Ltd.) was founded in 2015 in Tianjin and is one of the few Chinese manufacturers producing motorcycle tyres at scale. The Tianjin plant runs an annual capacity of more than 300,000 radial tyres across 150-plus sizes and five product categories — racing, adventure, off-road, cruiser and commuter — and KingTyre currently exports to more than 45 countries across Europe, South America, Asia and the Middle East.

Quality and compliance are certified rather than claimed: production runs under ISO 9001 quality management, and the range is certified to DOT for the United States, ECE R75 for Europe and CCC for China. KingTyre also runs OEM and ODM programmes for teams and resellers, including private-label moulding and branding — our private label and OEM motorcycle tyre manufacturer guide explains how that works in practice, and the wholesale importing guide covers the logistics and documentation side.

One point for importers specifically: the K82 is not in KingTyre's race tyre specification sheet, which covers the K00 slick, K01 rain tyre, K06 semi slick and K97 classic racing tyres only. Any specification you need for the K82 — tread width, overall diameter, rim width, cold and hot pressures, load index — has to come from the factory, not from the race tyre data. Ask for it in writing before you publish it in your own catalogue.

For a supplier assessment rather than a single SKU, read how to choose a motorcycle tyre manufacturer in China, and browse the complete KingTyre product range to see how the K82 sits alongside the dual sport and race lines.


Frequently asked questions

What is the KingTyre K82 good for?

The K82 is built as an all-terrain off-road dirt bike tyre covering woods riding, trail riding, enduro competition and desert racing. Its deep-block tread with reinforced side lugs and self-cleaning channels is what makes it work across mud, sand, rock and hard-packed ground rather than on one surface in particular.

How long do KingTyre K82 dirt bike tires last?

KingTyre publishes 3,500–5,000 km depending on terrain, about 20% longer than average. The lower end applies to rock and sand, where the blocks are abraded away quickly, and the upper end applies to maintained trail riding. Correct pressure for the terrain is the single biggest factor in reaching the upper end.

Are KingTyre K82 tires street legal?

KingTyre does not publish an ECE or DOT certification for the K82, so it should not be sold or presented as a road-legal tyre. It is an off-road product; check the sidewall marking and your local rules. If you need one certified tyre for both road and trail, the K67 90/10 and K60 50/50 dual sport tyres are the certified products.

What size dirt bike tire fits a 250cc trail bike?

KingTyre's own answer is the 90/90R21 front with the 140/80R18 rear, which is the standard combination on most 250-class enduro and trail machines. The full published K82 range is 90/90R21 and 120/70R19 at the front, and 140/80R18, 150/70R17, 150/70R18 and 170/60R17 at the rear.

Are K82 tires good for woods riding?

Yes — they are one of the main reasons the K82 exists. The deep blocks dig into soft ground, the wide spacing sheds mud and debris instead of packing solid, and the reinforced shoulder lugs hold the tyre when the bike is stood up on a steep off-camber corner.

Does the K82 work in mud?

Yes, and mud clearance is the design problem the pattern solves. Self-cleaning channels between widely spaced blocks let mud fall out rather than pack into a smooth, slippery surface, which is the failure that catches most riders out on a wet trail.

Does the K82 work for desert racing?

Yes, it is one of KingTyre's four published target disciplines. The heat-resistant compound and multi-ply reinforced carcass are what allow the tyre to hold its structure through a long desert stage, where a soft compound would overheat and a weak carcass would be punctured by rock.

Does the K82 fit a pit bike?

Not with the published range. The K82 is built from 17 to 21 inches, while pit bike frames typically use 10-inch or 12-inch wheels. KingTyre offers separate pit bike tyre models, so ask the factory about those rather than trying to fit a K82.

How does the K82 compare with the X85 and X86 motocross tires?

The K82 is the all-terrain trail tyre, the X85 is the aggressive knobby option for woods and mud with a wide void ratio, and the X86 uses closely spaced reinforced blocks for rock and hard-packed soil. For a race bike on a prepared track, the X85 or X86 is the sharper choice; for a trail and woods machine that also races, the K82 is the more usable one.

How do I order K82 dirt bike tires in bulk from KingTyre?

The K82 is supplied as a wholesale product with OEM and ODM packaging available for resellers and brands, and KingTyre quotes per order rather than publishing fixed prices. Contact the factory with the sizes, quantities and delivery schedule you need, and request the technical data sheet for the exact sizes — pressure, load index and construction details are not published online.
