I know first hand those tires are the cars pajamas. Got the same 255/55/15 on Blueballs. And 275/35/17 on the saw blades C4 corvette. Sleeper as hell. RII’s are amazingHow do these all compare to something like a 555RII? I recently bought a set of big sidewall RII's in a 275 to fix my 15x10 rear and I'm wondering how that loss of tire width translates to putting power down. My street tires are 315 Azenis on 18x11's and I just blow them off all over the place.
