Use our calculator or look up your tire below — then check camera hole options before you order.
Step 1 — Read Your Tire Sidewall
Look at the sidewall of your spare tire. You’ll find a number sequence stamped into the rubber. For metric sizes it looks like 285/70R17 — for named sizes like 33x12.50R15, the first number is already your diameter in inches.

P Tire Type • 285 Tread Width (mm) • 70 Aspect Ratio (%) • R Radial • 17 Rim Diameter (in)
Step 2 — Calculate Your Cover Size
Spare Tire Cover Calculator
Select a preset or enter your numbers — then verify against the size chart below

⚠ Important — always verify against the chart below. The calculator uses the standard formula, but actual tire diameter varies depending on tread depth, inflation pressure, and manufacturer tolerances. Tires with deeper tread (like mud-terrains) often measure larger than the formula suggests. If your result is borderline, measure your mounted spare directly across the full diameter or contact us to confirm.
📌 For named sizes (e.g. 33x12.50R15), the first number is your diameter — match it directly to the chart.
