I am going to look at some used tires to install so I can go to the track and tear them up without worry. I have Hankook stock size 255 on now and will be putting 285/35 on. They have some Goodyears and Toyo's that I know of, and will see what condition they are in when I go by to inspec. I just wanted to get an opinion on used tires and If anyone had experience with Toyo brand. I looked on the web and figured that they are the Proxies TR1 Y rated but not sure.
