How to Inspect and Maintain Off-Road Tires

Check the wheels and rims
Check wheel torque according to the vehicle manufacturer's recommendations. Inspect the rims for visible damage.

Inspect the tread and sidewalls
Look for punctures, cuts or dents in the tread, sidewalls or grip area. If damage is visible, the tire should be thoroughly examined internally and externally by a tire professional.

Look for casing damage
Do not drive on tires with casing damage, including visible or damaged cords, separation between components, deterioration caused by petroleum or corrosive products, or abrasion of the inner rubber resulting from driving with insufficient tire pressure.

Check the valve cap
Inspect the condition of the valve cap each time you examine the vehicle. When in doubt, replace it.

Check tire wear at several points around the tire to identify uneven or abnormal wear. Tread depth can be measured with a depth gauge or checked using the tread wear indicators when present.

When inspecting tire wear:

Measure at several points around the tire rather than checking only one location.
Use a depth gauge to measure tread depth, or check the tread wear indicators when present. Tread wear indicators may be identified by a symbol on the sidewall.
Replace the tire if the legal or technical wear limit has been reached.
Consult a tire professional if you find abnormal wear or a difference in wear between tires on the same axle.

There is no single service-life expectancy for an off-road tire. Tire materials and components change over time, and the rate of change depends on the conditions the tire experiences throughout its service life.

Factors that can affect tire lifespan include:

Climate
Storage conditions, including temperature, humidity and tire position
Operating load and speed
Inflation pressure
Damage caused by road or operating conditions

Because these factors vary widely, it is not possible to accurately predict the service life of a tire.

In addition to regular inspections by the user, tires should be checked regularly by a qualified tire professional who can determine whether they are suitable for continued service.
