Hey mark,
i am new to the site but do work at an auto shop. I have an 04 tb ls and have been looking into upping my tire size. I have the tough country 2.5 level kit but am running into the problem of the upper control arm being in the way with factory 16" wheels. Any advice other than putting adapter plates on my hubs? Just wanting like 285/75r16 or possible 255/75r17 on after market wheels.
