Re: Another newbie with a question or two...
Usually thread is used up at 1/8" or less remaining. I agree with last post on the pulling. My car has under 5,000 miles on the tires and it pulls dramatically to either side depending on road surface. Its much more sensitive to poor surface conditions (grooves, ruts) than most cars I've owned. I just hold the wheel tighter because IMO this same sensitivity gives the car its outstanding handling in the turns.
