Bought 4 firestone atx 235/75/15 back in 95. As of Aug 16, 2000 I had 3 left (extended from Road HAzard warranty). I was on the initial waiting list but decided not to wait, not b/c of fear of tire defect, but rather the wear and tear of about 60K miles on the tires. I am now waiting to be reimbursed for my new tires. I did have one firestone blowout on the FRWY.(it had over 50,000 miles on it though.
