Default 275/30-19

couple shots of my new P-Zero Nero GT 275/30-19s, 245/35 on the front... looks pretty normal. in fact after i got them i felt like i could easily go to 285 on the rear. but what the heck, i can run these for a couple years and if i don't love them i can try something different next time.

Ah you're correct; the 295 is essentially negligibly shorter. So are these cars heavy enough to where a 285/35/18 is going to feel like it's pushing over the sidewalls?

^ 285/30/18 is pretty much the same as stock. 285/35/18 is a bit off.



Took a few pics. PSS 245/35/19 & 275/30/19

Yes they are. I went with the recommended setup after reading around for a while.

Pretty sure that 18 was a typo. I think they meant to put 19.

^^^^Chart is correct. The OD of a 285/35/18 is 25.9".

275/35 is perfect in my opinion for our cars.
my setup is 275/35/20 and it sits flush with the fender. no rubbing no poking. the fitment gives the rear of my car a nice fat ***.

Doesn't make sense if you don't post what offsets the wheels are...

Your rear tire does not look like a 275 with a 35 profile to me

You guys are looking at OD when its really the sidewall flex that is going to ruin the handling. If you think this handles well you arent pushing hard enough. If you did a track day that didnt involve drag racing this set up wouldnt feel so good. To each his own, but when custom wheels with custom offsets can be had for $1200-$1600 for Forgestars or AG wheels Id say just go out and get the right size wheels. This is like putting a size 12 shoes on a person who is a ten and saying " I add some grip". No you didnt . Its just sloppy.
