Tire Mixing
Replacement tires should always have the same construction.
Tire mixing can be dangerous. Most passenger tires today are radial tires. For best performance, we recommend the same size and type of tire be used on all four wheel positions unless the vehicle manufacturer specified different sizes, front and rear, as original equipment. Check the vehicle placard.
On the front or rear wheel drive vehicles, if different size tires are used on different axles, always place the lower series tires on the rear axle.
If only two radials are mounted with two non-radials, the radial should be mounted on the rear. If tires of different types are mixed on a vehicle in any configuration, they should not be used for long periods and speeds should be kept to a minimum.
Mixing or matching of tires on 4-wheel drive vehicles requires special precautions. Always check vehicle manufacturers' manual for their recommendations.
