235 = section width in millimeters; 60 = sidewall as a percentage of width; 19 = wheel diameter in inches.
Sidewall height: 235 × 60/100 = 141 mm
Overall diameter: (19 × 25.4) + (2 × 141) = 764.6 mm
Circumference: π × 764.6 ≈ 2,402.1 mm
Read the size-code guide Overall diameter: (19 × 25.4) + (2 × 141) = 764.6 mm
Circumference: π × 764.6 ≈ 2,402.1 mm
What to check before changing size
Use the vehicle and tire specifications to check these three points:
- Vehicle placard and manual: match an approved size and the required load and speed ratings.
- Wheel specifications: check the tire maker’s wheel-width range and the wheel offset.
- Available space: check clearance at full steering lock and throughout suspension travel.
