Michelin 4s max tire size on 343m rims?

[Craze]

Just wondering do 305 width fit on rear without ugly bulge? Any negative effects? Thanks

I have Michelin PS4S 305 in the rear and they fit perfectly.

No sir, stock setup.

Confirm there is no bulge and noticing a slightly more comfortable ride with more grip.

I have 305/30/20 Michelin Pilot cup 2’s on the back (like the AMG GT and Lamborghini Aventar). No spacers and they still tuck in the fender.. there is still a little room behind the tire in that i could go a tad wider if there’s something available.
The PS4’s were brand new and hardly available when I decided on the PC 2’s... i also figured there was more grip in the PC’s... but i can spin them at will in the lower gears. I’m very surprised that they lasted 2+ years and i’m Still not at the wear bars... but am thinking of replacing them soon... I want better grip but also some wet traction for rainy days (i drove a Supra with drag radials and the tread disappeared way too quick and i spun the car).
