2005 Buick Rainier Question: Hub Assembly
Answer #1candaautomotive from C and A Automotive, January 10, 2011, 08:08Journeyman
Tire size has alot to do with the ABS and Trac Systems. The larger the tires the faster your speed. Each hub assembly has a wheel sensor that monitors the speed of each wheel. The ABS and Trac system reads this speed. It lets the computer knows if there is a problem? If you run different tire sizes on this vehicle each wheel will read different speeds at normal driving conditions. Which will cause a abs or trac to be set.

On a 4X4 or All Wheel Drive (AWD) vehicle, all the tires should match. If they're the same exact size, it should be OK but I'd rather see all 4 be identical tires for trouble free operation.
I haven't heard about particular hub problems but I notice that there are many wabsites selling hub parts for your vehicle so I guess there are failures in some vehicles. Take it to a GM specialist or a 4 wheel drive shop.
