Important: Equivalent tire sizes do not automatically mean that the tires are interchangeable on every vehicle. Before changing tire size or inflation pressure, always check:
  • Load capacity
  • Vehicle clearance
  • Recommended rim / wheel
  • Dual spacing
  • Tire manufacturer’s recommendations
  • Vehicle manufacturer’s requirements

Truck Tire Size Conversion & Equivalent Tire Sizes

Finding the right equivalent truck tire size is important when replacing conventional tires with radial or low-profile tires. Our Truck Tire Size Conversion Tool helps you quickly find equivalent tire sizes across 100 Series, 90 Series and Low Profile Series.

Simply enter your current tire size, such as 11.00R20, 10.00R20, 12R22.5, 295/80R22.5 or 315/80R22.5, and the tool will show the corresponding tire sizes listed in the conversion chart.

For example, 11.00R20 can be cross-referenced with 12R22.5 and several low-profile sizes, including 295/80R22.5, 315/80R22.5, 305/70R22.5 and 315/70R22.5. This makes the tool useful for fleet managers, tire dealers, technicians and transport operators evaluating tire size changes.

However, an equivalent tire size does not automatically mean that the tire can be installed on every vehicle. Before changing tire sizes, always verify load capacity, rim compatibility, vehicle clearance, recommended wheel specifications and dual spacing. Tire manufacturer’s load and inflation data and the vehicle manufacturer’s requirements should also be checked.

Use this truck tire size conversion tool as a quick reference to identify potential equivalent sizes before carrying out a detailed tire and vehicle fitment assessment.
