Any tire, no matter how well constructed, may fail in use as a result of punctures, impact damage, improper inflation or other conditions. The failure may create a risk of property damage or personal injury.

To reduce risk of tire failure, we strongly recommend the following.

ALWAYS check the air pressure in all your tires, including the spare, at least weekly, while cool.

Do not reduce air pressure when tires are hot. Use a tire gauge to check air pressure and maintain it at the level recommended by the vehicle manufacturer.

NEVER overload your tires. The maximum load carrying capacity of your tires is molded on the sidewall of each tire.

ALWAYS check your tires regularly for scrapes, bulges, separation, cuts, snags, or embedded foreign objects. See your OHTSU dealer immediately if any such condition is discovered.

NEVER operate your vehicle in excess of lawful speed limits, beyond maximum safe speeds determined by driving conditions, or at speeds greater than recommended for the tire you are using.

AVOID driving over objects that may damage tires through impact or cutting, such as potholes, glass, metal, etc.

NEVER drive on worn-out tires. Tires should be removed and replaced when the remaining tread depth is 4/32” on steer axles, or 2/32” on other axles. 2/32” remaining tread depth is indicated by tread wear indicators molded into the tread grooves.

NEVER spin your tires excessively during slippery conditions. The centrifugal forces generated by spinning may cause sudden explosion of the tire.

NEVER mix tires of different size or construction on the same axle.

IMPORTANT INFORMATION is molded on the tire sidewall. Among other information, the sidewall data contain the size, load range, maximum load and maximum pressure for that particular tire. WARNING: SERIOUS INJURY OR DEATH MAY RESULT FROM EXPLOSION OF TIRE/RIM ASSEMBLY IF PROPER MOUNTING PROCEDURES ARE NOT FOLLOWED. ONLY SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES. FOLLOW THE PROCEDURES FOUND IN THE RMA WALL CHART: “DEMOUNTING AND MOUNTING PROCEDURES FOR TRUCK/BUS TIRES”.

ALWAYS match rim diameter with the tire bead diameter.

NEVER mount tire on a cracked, bent, rusted, or otherwise damages rim, or a rim which has been repaired.

ALWAYS ensure the tire interior is dry before mounting. Moisture inside a tire can damage the casing.

NEVER put a flammable substance into a tire; explosion may occur.

ALWAYS clean and lubricate tire beads and rim seat with approved lubrication media. Do not use gasoline, diesel oil or any petroleum substance.

ALWAYS use a safety cage or other equivalent restraining device when inflating tires.

ALWAYS use an extension air hose with gauge and clip-on air chuck.

ALWAYS inflate with dry air from compressor having a properly working moisture filter.

ALWAYS stand clear and NEVER lean or reach over the tire/rim assembly during inflation.
