Mixing Tire Sizes & Types

DON'T MIX TIRES OF DIFFERENT SIZES AND TYPES ON THE SAME AXLE.

For optimum handling & control, Dunlop recommends fitment of four tires of the same type & size unless otherwise specified by the vehicle manufacturer. FOLLOW THESE ADDITIONAL GUIDELINES: Fit newest tires on rear axle. If radials & non-radials must be fitted to the same vehicle, fit radials on rear axle. If tires of different profiles must be fitted, fit widest tires on rear axle. Never mix radials & non-radials on the same axle. When fitting snow tires or all-season tires to performance vehicles, always fit in sets for four. Do not fit tires with differing speed ratings. Never mix sizes & types on the same axle.

Broadly speaking, tires should not be mixed. It is recommended that all tires on a vehicle should be of similar tread pattern, same performance rating, size & construction, unless the vehicle was engineered for front & rear tires of different sizes.
