Tire wear with 2" lift....need a adj. track bar?
Tired of my tires cupping and going out of round. Seems like if I miss one rotation and let it go beyond 4-5000 miles, they will cup and go out of round and forever shake between 50-55 mph. (running BFG 33 x 10.5, first go around was the A/T's, now the KM2's). Only got about 31,000 miles out of the A/T's, but that was my fault as I over inflated them. Now, the KM2's are at 45,000 miles and probably don't have enough tread to pass the next inspection next May.
But both sets have cupped and as I was told, were basically "un-balance able" as they went out of round.
So, when I got my first set of BFG's, I installed a 2" coil space lift, 1" body lift, and a 1" motor mount lift. Replaced the shocks at the same time. No vibes coming from the back end.....BUT, should I have installed an adjustable track bar to get the axles back where they should be? Will this increase the mileage of my tires and will they no longer cup? The stock set of tires that came with the Jeep brand new (prior to my lift install) from the dealer never cupped. Are the axles no longer pointed exactly straight ahead? It sees very little off road use.
