Tire Size Chart by Wheel Size
Every calculated width/aspect combination for a wheel diameter, with theoretical outside diameter, sidewall and circumference, plus a reference comparison.
Find sizes for a wheel diameter
Pick a rim diameter to see every theoretical width/aspect combination for that wheel, with its outside diameter, sidewall and circumference.
Every combination of width 155–335 mm (step 10), aspect 25–85 % (step 5) and rim 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24 in — computed from the size code (tyre-chart generator 2 (2026-10)).
Theoretical, unloaded geometry · D = 25.4 × rim + 2 × width × aspect / 100
247 calculated sizes in 1 rim group
- Note: Every row is a calculated combination — availability unverified. Whether a size is made, legal, load- and speed-rated for your vehicle or fits your rim and suspension is not shown here.

How to use this calculator
- Pick the wheel (rim) diameter — 13 to 24 in — to list every calculated width/aspect combination for it, or choose All rims to see each rim as its own group.
- Search for a width or aspect, limit the outside diameter, and optionally enter a reference size with a ±% band to compare diameters or keep only close matches.
- Inspect a size for its geometry and the speedometer illustration, and download the rim group or all filtered rows as CSV.
How it works
For each size on the chosen rim: sidewall h = width × aspect / 100, outside diameter D = 25.4 × rim + 2h (mm, exact inch), circumference C = π × D and theoretical revolutions per km = 1,000,000 / C. Difference = (D / D reference − 1) × 100 %, inclusive of the band limit.
The rows come from a stated generator (width 155–335 mm in 10 mm steps, aspect 25–85 % in 5 % steps, rims 13–24 in) computed from the size code — not an availability list — and each is marked calculated, availability unverified.
A size listed for a rim is a geometric combination only: whether the tyre is made, approved for your rim width, load- and speed-rated for the vehicle or clears the suspension is not shown. This is theoretical unloaded geometry, not rolling circumference.
Worked example
Sizes close to 265/70R17 on a 17 in wheel. 265/70R17 is 431.8 + 2 × 185.5 = 802.8 mm (31.61 in). With it as the reference and a ±3 % band, 245/75R17 (799.3 mm) is −0.44 % and inside the band, while 285/70R17 (830.8 mm) is +3.49 % and outside it.
Frequently asked questions
Are all sizes available?
No. The chart lists every geometric combination from the generator, marked availability unverified. Check that a size is actually manufactured and approved before buying.
Diameter or rolling circumference?
Theoretical outside diameter from the size code. The loaded rolling circumference is smaller and varies by tyre, wear and pressure, so treat speedometer figures as illustrations.
Does a matching diameter prove fitment?
No. Rim width, offset, load and speed ratings, clearance and local rules decide fitment. The vehicle placard and the tyre maker's data are the references.
Are these results safe to fit?
They're geometry estimates only. Real tyres vary by brand, load, pressure and wear. Always check the vehicle placard, manufacturer data, local road rules and guard/brake/suspension clearance, and get professional fitment advice before changing tyre or wheel sizes.
