@ ACHipo, Evan, I also did my homework when it came to tires. My biggest concern was look's (profile) as to stickiness (mainly a street car ) maybe a auto-x or two. The Avon's, MT SR's and such were not to my likely as I was building a street car, and everybody run's TA's or Cooper's, I wanted something different. I brought my MT from Proformance Tire in Cal. they went and looked at the set I brought and rating was 400. I have a few hot-rodder buddies and they like the MT St ride, and they smoke-up pretty good too

The other reason (size) very few company's build the 235-275 60 15. Just a head's up I'm Tom not Andy
