Tyres
If you replace two tyres, which axle should they go on?
The correct axle depends on the vehicle, tyres and technical guidance. Ask a tyre specialist and the manufacturer rather than applying a blind rule.
Fitting a new pair means considering grip, wear, drive type and compatibility. Apply technical recommendations to the specific vehicle and tyres.
Do not decide by drive type alone
When you replace two tyres, a tyre specialist will assess the remaining pair, sizes, tread pattern and manufacturer guidance. Knowing whether the car is front-, rear- or all-wheel drive is not enough to choose the axle yourself. Recommendations aim to keep handling predictable and reduce the risk of losing grip, especially on wet roads; the fitting must match the vehicle specifications.
Check that the two new tyres are compatible with the ones being kept and that both axles meet the required size, load index and speed rating. Mixing models or characteristics can affect handling and driver-assistance systems. Some all-wheel-drive vehicles require very similar rolling circumferences: ask the manufacturer or a qualified centre before replacing just one pair.
Ask for a professional assessment
Before the work, ask the tyre specialist to measure tread depth and wear on all four wheels and check for damage. Ask which pair will be replaced and on which axle, with reference to the manufacturer’s guidance and the tyres’ condition. Uneven wear may mean the alignment, suspension or pressure also needs checking.
After fitting, check the pressure, tightening procedure and whether the wheels need balancing. If the vehicle uses sensors or requires an initialisation procedure, follow the handbook and workshop’s advice. Do not reuse a damaged tyre just because it still has deep tread.
Check how the car behaves after the change
Drive carefully for the first few journeys and tell the tyre specialist about any vibration, noise or warning light. Do not brake sharply to test the tyres. Check pressures when cold against the vehicle’s figures and inspect wear periodically to spot problems early.
When replacing only two tyres, tyre manufacturers generally recommend fitting the new pair to the rear axle, even on a front-wheel-drive car, to keep the rear end more stable on wet roads. Still check the car manufacturer’s guidance and compatibility, especially on all-wheel-drive vehicles.

Frequently asked questions
Should new tyres always go on the rear?
This is a common stability recommendation, but have the vehicle manufacturer’s instructions and the tyre specialist’s assessment applied to your car.
Can I replace just one tyre?
It depends on the damage, compatibility and vehicle guidance; ask for an assessment before fitting a single tyre.
