We are going to try and stretch ours out before we try to run them again on my brothers trans am. Maybe we can get them a little closer. Just something for anyone to keep in mind who runs a large size tire and is thinking about going to M/T. Not sure what # tire my firends were. I have a set of M/T currently on my Monte Carlo and they are working well, but it isn't worth the chance to buy another set of tires that the company will not back up. We pulled a 1.03 60ft and running 4.65 in the 1/8th this weekend, but I only have a 582ci motor with conventional 24 degree heads and one system in a 2530 lb doorcar. Going to try and step it up and get into the 4.50s. Didn't have the Nitrous timer zeroed out this pass weekend.
