Lead Thrower, The rim has weight tape marks in three places now from moving the tire around. The store says as long as it balances they will leave it on. The last time it was in, this, as you said, kid, put all 4 on the machine, said they were all fine, I said lets go for a ride then, and a different, older guy came out and did the tires, found it, more lead is the cure. As soon as these tires are shot, Discount Tire gets my business.
