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.

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

Necrothread, but has anyone mounted a 225 RC1 on a 10" wheel, or is that too much stretch? I haven't been able to find any pics in this thread or on the trackable miatas FB page
My car will need 15x10ET25 wheels for fitment purposes, but I'm considering competing in a series that limits tire sizes top 225 for cars under 2550lbs.

205s on a 9" wheel is the norm here for CA track miatas with <150hp, so I'm hopeful that 225s on a 10 isn't going to be too insane. If it is, I'm going to have to figure out a pretty crazy spacer situation to get fitment correct on 9" wheels
Edit: This is specifically for the RC-1, which has a listed section width of 9.1"
Edit 2: Nvm, I'm just gonna run spacers with a 225 on a 9
