AWD/4WD VEHICLES
You should not mix tires in any way on an AWD (all-wheel drive) or 4WD (four-wheel drive) vehicle. If you drive a 4WD or AWD, your tires should match in tread depth, brand, model and size. Mixing tires in any way on these types of vehicles can cause wear and/or damage to the vehicle’s drive train.

Is it OK to have tires with different tread depth?
Primarily, you should avoid mixing different tire brands and different tread patterns. There are rare exceptions for approved mixed-tire fittings, but in general, manufacturers do not recommend tire mixing at all.

Why is tire inspection and tire size important when diagnosing an AWD or 4WD system?
A tire’s size, or more specifically its circumference, is important because a larger tire travels further with each rotation than a smaller tire. Although such variations may seem insignificant to the naked eye, they cause various 4WD and AWD drivetrain components to rotate at different speeds, which increases wear.
