Width in mm · aspect = sidewall height as a % of width · rim in inches

Flotation (LT) sizes, all in inches: overall diameter × section width, then rim

Well within tolerance

−0.76% diameter

The overall diameter changes by less than 1.5%, so speedometer error is negligible and ride height barely moves.

Needs 13″ wheels: this tire does not fit your 14″ rims.
20 mm narrower: check the tire is approved for your rim width.

How to use the tire size calculator

Put your current tire size — width, aspect ratio and rim diameter — into the first form, then your desired size into the second. You’ll get the difference between the new and the old size, plus the speedometer reading difference and your actual speed on the new set. Both metric and flotation (LT inch) sizes are supported.

The calculator helps you decide whether a set of tires and wheels will fit your car. To compare tires by brand and model instead, use our tire comparison tool; to look up factory sizes, browse by car make.
