Hey folks,

I think I've read most of the wheel/tire-related threads before posting this thread. I recently added RS fenders (which i obtained from @JCR-Porsche) to my 991.2 GT3 (build log coming soon), so I have the ability to increase my track width now.

From the most popular wheel/tire threads, it seems like most RS people who run 19s are running 19x9.5"+50. I already run that on my non-RS, though, so it seems unnecessarily mild. @SupremePower, who is an incredible resource on this forum, says I can 20mm more!

I also see that while most RS drivers appear to be buying Apex's 9.5+50 fitment, Apex also offers 19x10+42 fitment for RSes, which would push the outer edge of the wheel out 14mm.

Do any regular track-goers here run 19s that are more aggressive than 9.5"+50 on their RS?

Thanks!

 

I'm more concerned with tire size and how the tire choice fits on the wheel than i am about getting the biggest wheel to fit. I ran a 275 CR-S on the front of my RS and found it to be great compromise of grip vs. steering feel while not overwhelming the rear as i was still running a 325. I know you can fit an even bigger tire on the front but not sure why you would unless it's a competitive car for TT or something.

 

Yea, I'm with you on that. I run 265/35-19 GoodYear SuperCar 3Rs up front (and 325/30-19 in back). I'm not really trying to fit a wider tire; I'm just trying to offset (push outward) as much as possible for the widest track.

The reference point of the 10" wheel is mainly because a 10" width with 42mm offset implies one could fit a 9.5" wheel with 36mm offset, even though most folks are running a 9.5" wheel with 50mm offset. So basically, I'm trying to verify whether I can safely get that additional 14mm of track width.

 

991.2 GT3 RS here --

I'm running 19x10 ET42s with no problems on track. I use Goodyear 3R in 285 and the fitment looks badass. You can also run 265 fronts if 285 aren't available

 

Thanks for letting me know! Do you happen to have any pics you're willing to share?
