Mixing Tyres on an Axle

Introduction

This document outlines the considerations regarding mixing tyres of the same size and load/speed rating but with different tread patterns on the same axle.

Problem

Can tyres with identical specifications but different tread patterns be safely and legally used on the same axle?

Solution

While it may not present a significant handling issue on the rear axle, it is generally recommended to avoid using tyres with different tread patterns on the same axle. Regulations regarding this practice vary by region.

  • It is preferable to have identical tyres on the same axle, and if mixing is unavoidable, to ensure tyres are the same from side to side.
  • Mixing tyres on the front axle is generally not recommended due to potential handling implications.

Relevant Parts

  • Tyre Size: (Example) 265/70R17
  • Load Rating: (Example) 115
  • Speed Rating: (Example) T
