I run the STT's in 285/75/R16 on my 98 12v. I really like the way they handle and ride. I have over 20,000 miles on them and show no signs of erratic wear or other problems at all. I do rotate them and have them rebalanced every 2nd service at the shop who mounted them for me. For the price they charge I can not get my jack and tools out that cheap.
I had a set of the ST's first and loved them also. They had 65,000 miles on them when they were removed and still had about one summer left if you needed to push them. I had them taken off for a different look for show season.
Some like Coopers,Some do not,Myself,I would reccomend them to anyone... Andy
Here is a shoit of mine at the recent Buck Motorsports Park Show-N-Shine with them on.
