Rear tire wear GS350
Hey guys on my 08 GS350 AWD with staggered 20's and stock ride height. Ive been having rear tire wear for the longest time. I cannot seem to track down the problem.
Many alignment shops have aligned this car, the car will align properly all within spec. But I keep getting inside feathering almost like toe damage. Even with stock wheels and tires I will get the uneven wear.
I mainly use this car for long highway trips. Something ive noticed at time the car will want to pull hard on the right, but when I shake the steering wheel it will center itself out. That leads me to believe its a bushing issue. But we have tested all the bushings and none show any movement. Maybe the suspension is binding somehow and when I shake the steering wheel it loosens up?
Things I have replaced:
1: Rear Shocks
2: Rear aftermarket chamber adjustment arms
3: Oem toe arms

What are the wheel widths you are running? ( 8.5 inches front can do that on Lexus cars )
What are your tire sizes? ( Tire wall sizes, low profile 30's or 25's can cause that )
What pressure are you running on your tires? ( Sometimes even 35PSI can be underinflated, you may want to consider 40 )

Hey Designo,
8.5 front 10.5 rear 245/35/20 275/30/20
Stock wheels and tires, before this set had the same wear pattern. Its like half the tire forms a wave. From that my tires are starting to roar a bit. I thought about replacing all the suspension arms in the rear but thats pretty costly. All the bushing are solid after the tech used a pry bar on them.
