I saw one direct comparison of the sm7 take offs to the wider RC1. Seems like they are actually comparable grip wise and obviously last longer.

I can get SM7's for roughly 200$ a set and get 2 to 3 days which works out to 8 to 12 heat cycles, out of them before they cord. One issue is I can get them greasy after 5 to 10 laps with 250whp and 2450 on track weight.

The question is could I expect similar grip and 25 to 35 heat cycles but more temperature tolerance out of a 245 RC1?

I'm also planning to increase power to 350whp or more and was hoping the RC1 would be economical alternative to the SM7'S.

You're looking for an economical alternative to used tires for 350whp?

That was my take. Doesn't make sense.

Come on now I'm crazy for considering anything but brand new 1200$ a set 245 hoosiers?

Just trying to maximize my dollar on track, I'm just a HPDE bum and I'm not necessarily concerned with the fastest tire but it'll get a bit dicey trying to put that kind of power down through RS4'S

Found a used set cheap enough to give them a try. 205 sm7 mounted on a 9" wheel for comparison. 245 RC1 is unmounted.
