I currently have Forgestar F14 19x10" rims on the rear with a 285/35/19 mounted. Fenders have been rolled to make sure everything is clear. I am looking at new rear tires and wonder if 305/30/19 Pilot Super Sports will fit with no rubbing?

I am willing to pull them a bit if needed, but using the tire calculator's around the web, it appears the difference is .75" total or less then half inch on each side.

Current tires are RE-11, as I know some tires run wider then others.

First off, measure to see what kind of clearance you have now. I am pretty sure several people have mounted 305's with the right offset.

^^ that was just dumb ^^

I'm running 285 Michlin PS2s right now on 9.5" CTS-V wheels, and I know for a fact I have the clearance on the outside to step up to a 305. Haven't checked the inside yet.

Just measured the rim and it is 19x10 with a +42 offset. (give or take!)

+44 is probably what it is, I posted on the other forum as that was the max you can get in 19x10 with the Forgestar F14.

I don't think it's going to work, I know a 305 would not work with that offset in a 20. With that offset I think you are going to max out at a 285. Again that was with a 20 so you may want to compare on one of the calculators.
