Default Will 295/30/19 rub on stock height isf

I've tried searching but couldn't find a definitive answer. I'm planning on putting 255/295 on my 2012 stock rims at factory height, I really feel the 225/225 being under sized for this car. I was wondering if I would have any rubbing issues. I don't plan on lowering the car in the future as of right now. If anyone has pics of this setup that'll be great if you could post some. Tires will be PSS or ps4s.

Thanks

That's a bit of a stretch (no pun intended) for the rear wheels. I can tell you my experiences. When I had stock wheels ('08) so ½" narrower than yours, I ran 245/35/19 and 285/30/19. This setup is not recommended by the tire manufacturer's, and there was some sidewall bulge in the back, but handling was improved IMO. Some members here tried the same setup, and thought handling was degraded over the 245/275 combo on the 8" and 9" wheels. I ran Bridgestone S-04.

Running a 295/30/19 on a 9-½" wheel is also not recommended by the tire manufacturers.

I am now running 295/30/19 and 255/35/19 on RCF wheels, 9s and 10s. Also Bridgestone S-04. Handling is GREATLY improved over any of my previous setups and I am now right where I want to be. My rear fenders are rolled flat and there is still minor rubbing, but only with people in the back seat, a heavy load in the trunk, or if I go too fast over a noticeable bump. Don't believe you will have the same issue because you rear offset is +51mm in back and mine are now +41mm.

I totally agree with you, the ISF in any of it's guises is undertired. Try it at your own risk, but IMO, the safer approach would be to use 285/30/19 in back. If you want Michelin's, I don't believe they come in that size.

Note - I am at stock height and have absolutely no plans to lower my F!

Too wide for stock wheel width, do not recommend

Ideally I would go with 285/30/19 but they don't make them in for the pss or ps4. I guess I'll stick with the 275s then.

^^^^That was the reason I went with the Bridgestone Potenza S-04 Pole Position in the second place. In the first place I went with Continental ExtremeContact DW. Those tires were a disaster for me. The S-04s on the other hand are a GREAT tire IMHO, and they are available in 285/30/19.
