My friend dealt with the wheel weight issue on his last tire rotate and balance. Rookie tech mistake. Took about a month before the wheel weight become noticeable loose. He opt to get a new set of tires from 4Wheelonline and the shop gladly assisted him.
8" should be safe. Check out this thread:
The Rebel 6, 18x8.5 or 18x9 fuel wheels was mentioned there along with Ridge grappler which is a great combo imo.
My uncle recently acquired this XLT and he's not used to loud turn signals. Maybe he'll consider that cluster upgrade. It's in the shop for the installation of the new tires from 4Wheelonline. I'll mention the cluster upgrade tomorrow.
My uncle is looking at this Platinum and the current owner mentioned rubbing and he suspects it's the inner fender flap. We'll take a look at it after we installed the brake pads and mud tires on the Wrangler this week. We'll see which trick would work.
