Anyone running 345/30/19 without any problems.

I have 355/30R19 Kumho ACR's on the rear, with rear camber set at -2.2* I only have some "slight" rubbing under hard compression on track.

345/30/19 fits fine, at least for me

What tire options are you guys going with or considering? I plan on going 345 with my soon arriving APEX wheels. I would love PS4S but they don't make them yet in that size, PSS are available and are equivalent. Also started looking at R88R and similar, my car is loud but on the highway cruising (valves shut) it quiets down pretty far. Concerned with R888R noise levels.

On my ZLE I run PSC2 in 345/30/19. I moved the wiring harness, and now no rubbing.

I don't know if these fit the same on a non-1LE, and you need 12" wheels.

On a side note... this weekend I re-confirmed something about PSC2 that I already knew, PSC2 are TERRIBLE tires for ZL1 on track due to the weight of the car. Do not buy PSC2 for track, they're fine for canyon performance but they heat cycle out and are like roller skates at track temps after only 4-5 heat cycles. Even in 315 front and 345 rear there is not enough rubber to overcome the poor grip once they cycle out.

I've seen you post about your setup before but please remind me, what do you run on the front with the Viper spec front Kumho ACR being too small and non-ACR not sticky enough? RE71 in 305?
