DUNLOP TIRE LIMITED WARRANTY W A R R A N T Y bead seating. Lubricate beads and tire rim (including tube or flap) contact surfaces. Lock assembly on mounting machine or place in safety cage, stand back and never exceed 40 psi to seat beads. Never use a volatile substance or a rubber "donut" (also known as a bead expander or "O-ring") to aid bead seating. Only specially trained persons should mount tires. There are a number of serious injuries encountered each year as a result of tire-mounting accidents. Don't Mix Tires of Different Sizes and Types on the Same Axle For optimum handling and control, Dunlop recommends fitment of four tires of the same type and size unless otherwise specified by the vehicle manufacturer. Follow these additional guidelines: Fit newest tires on rear axle. If radials and 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 and non-radials on the same axle. When fitting snow tires or all-season tires to front-wheel-drive and performance vehicles, always fit in sets of four. Do not fit tires with differing speed ratings. When replacing tires, always consult vehicleand rim-manufacturer requirements for safety. Use of lift kits and some vehicle/tire combinations can cause instability. When changing sizes, carefully check vehicle/tire clearances. Do Maintain Vehicle Suspension, Wheel Alignment and Balance, and Rotate Your Tires Lack of rotation, worn suspension parts, underinflation/ overinflation, wheel imbalance and misalignment can cause vibration or irregular wear. Rotate tires at maximum intervals of 6,000 miles/9,654 km. Note: Where applied, speed ratings are indicative of high performance characteristics based on ECE 30 or ECE 54 European Indoor Wheel Testing as 60 Y o u r W a r r a n t i e s i n D e t a i l
