17-Inch Motorcycle Tires: The Complete 2026 Guide (Sizes, Compounds, Street vs Track)

Quick answer: KingTyre builds 38 distinct 17-inch tyre sizes across 71 size entries in 12 product families — from track-only racing slicks to street-legal sport tyres, adventure dual sport, cruiser and mini trail. Every 17-inch specification, code, weight, measured rim width and factory cold/hot pressure for the K00 racing slick, K01 rain tyre and K06 semi-slick are published below.

Last updated: November 11, 2026. Race tyre dimensions and pressures are taken from the KingTyre official race tyre chart; road tyre data is taken from the current KingTyre product matrix.

Why 17 inches became the standard motorcycle wheel size

Seventeen inches is the size that modern motorcycles settled on, and it is not an accident. A 17-inch rim gives a short, stiff chassis the steering response and lean-angle confidence it needs while keeping the tyre's contact patch long enough to actually transmit that steering into grip. It also solves a packaging problem: a 17-inch rim fits inside the narrow swingarm arms of a modern naked bike or a faired sport bike, where an 18-inch or 19-inch wheel would need a wider, heavier, and less rigid rear end.

For a tyre manufacturer, the consequence is straightforward — the demand concentrates on 17 inches. Across the whole KingTyre catalogue, 17-inch sizes are the single largest size family on the shelf. That is why this guide is built around a complete 17-inch listing rather than a handful of popular sizes.

Three labels you will see on a 17-inch tyre explain what it is built for:

• NHS (Not for Highway Service) — a racing-only construction. The K00 and K01 carry this marking and are not legal for road use in any country.
• ZR — a speed-rated construction that permits higher speeds than a standard radial.
• R y B — R denotes a radial carcass, B denotes a bias (cross-ply) carcass.

The KingTyre 17-inch range at a glance

Track and race 17-inch sizes: K00, K01 and K06

Thirty of the 71 17-inch entries sit in the three track families. These are the sizes that carry the most published engineering data, because these are the tyres that run in the 24 Hours of Le Mans.

Three columns in that table deserve attention.

Approved rims are wider than a single value. A 120/70R17 is built around a 3.50-inch measured rim, but the factory approves 3.50 to 3.75 inches. Fitting the narrowest approved rim changes the tyre profile, so always fit within the approved range rather than to a single nominal number.

Cold and hot pressures are different numbers, and both matter. The cold pressure is the safe value for the paddock and the road. The hot pressure is what the tyre actually needs the moment it leaves the warmers. For the K00 slick at 200/60R17 the difference is 1.4 bar cold against 1.6 bar hot — a 0.2 bar step that a tyre at operating temperature can be very sensitive to.

Not everything is published, and that is deliberate. Tread width and overall diameter are published only for the K00 racing slick. For the K06 semi-slick the factory publishes the measured rim, the approved rim range and the cold and hot pressures, but withholds the tread width and overall diameter. Where the factory has not published a figure, this guide says "Not published" rather than estimating one.

Warm-up protocol for 17-inch race tyres

Choosing a compound for a 17-inch race tyre

Compound choice is a track-and-budget decision, not a performance ranking. A soft compound on a hot track will overheat within a few laps, and the tyre will be at the end of its useful life before the session ends. For endurance duty it is the harder compound and the correct warm-up routine that actually deliver the finish.

Sport street 17-inch sizes: K97, K905 and K902

The street side of the 17-inch family is where most riders buy. The K97 is the sport on-road workhorse, the K905 sits between street and track, and the K902 is the long-distance touring version.

Note the speed and load ratings on this table, because they are not interchangeable between models even where the size code matches. A 120/70ZR17 in the K97 is published as 58W — load index 58, speed rating W. The same size in the K905 and the K902 is published with a speed rating only. The load index tells you what the tyre is certified to carry; the speed rating tells you what it is certified to sustain. If your replacement tyre carries a lower rating than the one you removed, the handling changes even though the size still fits.

Why the K06 semi-slick belongs on a street bike

The K06 is the only 17-inch tyre in the range that does both jobs. It carries a ZR speed rating, it is legal for road use in properly homologated markets, and it is built with the same four-compound system as the race slicks. Riders who want track-day performance without a second set of tyres choose it for exactly that reason. The full comparison against a full slick is in our guide to slick versus semi-slick motorcycle tyres, and the track-day use case is covered in the K06 track-day guide.

Adventure, dual sport and off-road 17-inch sizes

If your 17-inch rim carries an adventure or dual sport tyre, the size alone will not tell you the right tread pattern. The ratio does that.

The 150/70R17 is the most versatile 17-inch size in the catalogue — it is available in four different constructions (K66 80/20, K67 90/10, K60 50/50 and K82 off-road/supermoto) and it is the size most commonly fitted to adventure and supermoto machines. If a distributor needs a single 17-inch SKU that covers the widest demand, 150/70R17 is the most efficient choice in the catalogue.

The 170/60R17 is the other multi-construction size, available as the K66 80/20 and the K82 off-road/supermoto. Note that the K66 version is rated 72V while the K82 version is rated 72H — the speed rating difference reflects the construction, and it is the reason an off-road tyre is never simply a substitute for an ADV tyre in the same size.

For a fuller treatment of the ratio decision, see our 80/20 dual sport guideEl best 80/20 tyres of 2026 comparison, and the 90/10 adventure touring guide.

Cruiser and mini 17-inch sizes

The 130/80B17 in the K91 is a bias construction, which is worth understanding before you order it. Bias tyres flex differently from radials and are typically fitted to cruiser and touring platforms with wider rims. It is also the only 17-inch bias tyre in the KingTyre catalogue.

The K903 mini trail tyres at 60/90R17 and 80/90R17 are built for off-road mini bikes. Their narrow recommended rims — MT1.4 and MT1.85 — are what make them work on that platform. The factory data for these two sizes does not publish a speed or load rating, so check the approval marking on the tyre before fitting them anywhere.

For cruiser fitment guidance, see the K91 cruiser and touring guide.

How to read a 17-inch tyre size

Take the most common 17-inch sport size, 180/55ZR17, and read it in four parts:

• 180 — nominal section width in millimetres. This is the tyre's width, measured at the widest point of the tread.
• 55 — the aspect ratio. The sidewall height is 55% of the section width, so 180 × 0.55 = 99 mm.
• ZR — the construction and speed zone rating.
• 17 — rim diameter in inches. 17 inches = 431.8 mm.

That gives you a way to calculate the overall diameter: rim diameter plus twice the section height. For 180/55ZR17, 431.8 + 198 = 629.8 mm.

Why the calculation is only a guide

The nominal aspect ratio is a standard, not a measurement. Actual moulded section height varies between models and between production batches, so the calculated diameter and the real diameter are not always identical. Here is how KingTyre's own measured diameters compare with the calculation, using the published race tyre chart:

Four sizes match the calculation exactly. The rest differ by up to 8 mm — and the 200/65R17 differs by 8 mm in a direction that matters, because it inflates the overall diameter to 700 mm. If your bike's speedometer or ABS is calibrated to a specific rolling diameter, a larger-diameter tyre in the same nominal size genuinely changes gearing and ABS behaviour. This is exactly why the measured figures, not the arithmetic, should decide the fitment.

17 vs 18 vs 19 inches: can you change size?

You can, but you should not do it casually. Four things change together when the rim size changes:

1. Overall diameter. The same tyre size on a larger rim is taller, which raises the centre of gravity and changes the gearing.
2. Tyre width and available rim. A 180-section tyre on an 18-inch rim needs a wider rim to support the same profile, and the fitment changes with it.
3. ABS and traction control calibration. The wheel speed sensor reads the wheel speed, and a different rolling diameter produces a systematic error.
4. Suspension geometry. The effective travel and ride height both move.

The safe rule is to change front and rear together and to stay within the manufacturer's approved fitment list, which normally lists a specific rim width range and a minimum and maximum overall diameter.

This is also where the 17-inch decision gets interesting for the K97 classic race spec: the K97 race pattern exists at 18 inches (90/90ZR18, 100/90ZR18, 110/80ZR18 and 120/70ZR18), which is the classic superbike dimension, while the K97 sport on-road pattern covers 17 inches for modern chassis. Same family, two eras of geometry.

Which 17-inch size fits your motorcycle

The table below lists the 17-inch sizes most commonly specified by motorcycle manufacturers for the positions shown. Always confirm against the tyre placard on your own bike and the owner's manual — fitments vary by model year and market, and this guide is a starting point, not a substitute for the placard.

Are 17-inch slicks street legal?

No. Every 17-inch racing slick and rain tyre in the KingTyre range carries the NHS (Not for Highway Service) marking, which means it is not approved for road use anywhere. The K00 and K01 are track-only products.

The 17-inch semi-slick K06 is a different case: it carries a ZR speed rating and is designed to be street legal in markets where it carries the appropriate approval marking. The complete country-by-country breakdown, including the exceptions that do apply, is in our guide to whether slick motorcycle tyres are street legal.

How to choose the right 17-inch tyre

Work through these four questions in order:

1. Where does the tyre actually spend its life? Pure track, mixed street and track, or all road. This eliminates two thirds of the catalogue immediately.

2. Which construction does that need? NHS track-only (K00, K01), ZR street-capable semi-slick (K06), ZR or R street (K97, K905, K902, K66, K67, K60, K82), or bias cruiser (K91).

3. What does the size code on your rim and swingarm allow? Match the nominal size first, then confirm the recommended rim width against the rim you actually have.

4. What rating does the tyre need to carry? Check the load index and speed rating on your existing tyre and do not accept a lower rating than the one you removed.

Buying 17-inch tyres in bulk

For distributors, importers and racing teams, the 17-inch size family has a very specific commercial advantage: a single size can be ordered across multiple constructions. A dealer stocking 150/70R17 can serve an ADV buyer (K66), a road-focused adventure buyer (K67), a trail buyer (K60) and a supermoto buyer (K82) from one SKU position and one shipping volume.

For teams and distributors buying track rubber, the same applies to the race sizes — 120/70R17 is supplied across all three track families (K00 slick, K01 rain, K06 semi-slick), and 180/60R17 across the K00 and the K06, each with full compound selection.

Commercial and technical points worth confirming before you order:

• ECE R75 and DOT FMVSS 119 documentation for every road-legal SKU. The difference between the two standards is explained in our ECE R75 versus DOT comparison, and how to read the sidewall markings is covered in DOT and ECE tyre codes explained.
• Compound availability — the K00 and K06 are supplied in four compounds each, and not every compound is available in every size.
• Container planning — the volume per tyre varies widely inside this one size family, from 0.0122 m³ for the 60/90R17 mini trail tyre to 0.0632 m³ for the 200/60R17 racing slick. Build the container plan from your actual size mix rather than from a per-tyre average.
• Traceability — every tyre carries a batch code for compound and date tracking, which matters for race and fleet buyers.

Frequently asked questions

What is the most common 17-inch motorcycle tyre size?

120/70ZR17 for the front and 180/55ZR17 or 180/60ZR17 for the rear are the most widely specified 17-inch pairings on modern sport bikes and naked bikes. In the KingTyre catalogue, 120/70ZR17 is the most widely shared 17-inch size, available in five models: the K06, K97, K905, K902 and K66.

Is a 17-inch wheel better than 18-inch for a sport bike?

Neither is better in isolation. 17 inches is lighter and more agile with a shorter steering arm; 18 inches gives a stiffer rear end and more stability under hard acceleration. Modern supersport machines use 17-inch front and rear, while modern naked bikes often pair a 17-inch front with a 17-inch rear as well. The deciding factor should be the manufacturer's approved fitment list, not preference.

Can I run a wider 17-inch tyre than my bike came with?

Usually yes, within limits. A wider tyre on the same rim width changes the tyre profile and therefore the overall diameter. Check that the resulting diameter still falls inside the manufacturer's permitted range and that the load index and speed rating are at least equal to the original.

Are 17-inch racing slicks legal on the road?

No. The K00 racing slick and K01 rain tyre carry the NHS marking and are not approved for road use in any country. The K06 semi-slick is street legal where it carries the appropriate homologation. See our country-by-country street legal guide.

What tyre pressure should I run on a 17-inch tyre?

Use the pressure printed on the tyre, which is the cold value, and start from the vehicle manufacturer's recommendation if the two differ. For track use, the K00 and K06 follow a cold-then-hot protocol with a 60-minute warm-up at 80–90 °C, and the hot pressures are published in the race table above. The racing slick pressure guide covers the reasoning in more detail.

Does the letter after the size matter, such as R, ZR or NHS?

Yes, decisively. R is a radial construction, ZR is a radial built to a higher speed rating, and NHS means the tyre is for racing circuits only and is not approved for highway use. A 180/60R17 and a 180/60ZR17 are not interchangeable, and an NHS tyre should never be fitted to a road-legal machine.

Is 150/70R17 a good all-round 17-inch size?

It is the most versatile size in the KingTyre 17-inch range because it is supplied in four different constructions — the K66 80/20 ADV, the K67 90/10 adventure, the K60 50/50 dual sport and the K82 off-road/supermoto — all on the same 17-inch rim with a 4.25-inch recommended width. That makes it an efficient stocking choice for distributors.

Does KingTyre supply 17-inch tyres in containers?

Yes. 17-inch sizes are available across the full catalogue and are supplied wholesale to distributors and importers in 45+ countries, with ECE R75, DOT, ISO 9001 and CCC certification. Ask for the size-by-construction availability list for your market.
