Consult your tire owner's manual for proper maintenance instructions. An impact can cause a tire to fail, resulting in serious injury or death. Before mixing types of tires in any configuration on any vehicle, be sure to check the vehicle owner's manual for its recommendations. Only tire professionals should mount tires and they should never inflate beyond 40 psi to seat the beads. Serious injury or death may result from explosion of tire/rim assembly due to improper mounting. To ensure correct air pressure and vehicle load, refer to vehicle owner's manual or tire information placard on the vehicle. WARNING: Serious or fatal injury may result from tire failure due to underinflation or overloading. Tires for a particular dimension of a given tireline may vary in appearance from the tire shown in the photograph. > Tread patterns are often tuned to accommodate different tire widths. > Section width varies approximately 0.2" (5mm) for every 0.5" change in rim width. Some tires may vary from this value by +/-3% of the section height (affecting overall diameter), and +/-4% of the section width. > The sizes shown are average design values for tires measured on specified measuring rim widths. Government UTQG Ratings do not apply to light truck sized tires.
