It’s a good idea to replace all four tires at once. For optimum handling and control we recommend they are all the same type and size, unless otherwise specified by the vehicle manufacturer.
If you’re only buying two, make sure the new ones match the tires you’re keeping, and that this is permitted by your local laws and by the vehicle manufacturer.
- Put new tires on the rear axle
For better traction and stability when you drive, if you are only buying two new tires put them on the rear wheels.
If both must be fitted to the same vehicle, put the radials on the rear axle.
