This stuff was very educational.....
Our recommendation on all (90 and newer GM w/ IFS)vehicles with the 4" to 6" lift is a maximum of a 15x8 aftermarket wheel and a maximum of a 35x12.50x15 tire. This wheel has over 2 times more offset than stock. This combination, in our experience, does not seem to accelerate the wear of front end components over a stock wheel and tire arrangement appreciably.
Other Possible Combinations:
15x10 Aftermarket Wheels
These wheels have over 3 times more offset than stock and the additional leverage DOES accelerate the wear of front end components. Front end components are: Idler Arm, Pitman Arm, Tie Rod Ends, Upper and Lower Balljoints, Upper and Lower Control Arm Bushings, and CSS bushings (if so equipped). As these components wear the alignment and front end geometry is affected which results in poor tire wear and cupping, front end vibrations, shimmy and shaking, and other undesirable affects.
Does anyone really know how fast all this stuff wears out.....? Just need to know when to expect it...i am going to put on the 15x10 hellcats or the eagle 58 series........
