Does anyone know if I can run a 255/35R19 for the rear wheels (stock F-Sport wheels)? The staggered stock set up is a 265/35R19 and I know many people are running 275/35R19. I want to go with the Pirelli P7, but they no longer make 265 and 275, only 255.

Also, anyone running the Pirelli P7 set up know if the 70K mile warranty will apply to staggered set up? Thanks!

I have the same car & would not recommend running a smaller tire front or rear. GS is a pretty heavy car & the stock size is low profile enough. It may interfere with the stability control system, it will speedup the odometer putting miles on the car faster than actual. It will ride rougher too.

Most manufacturers' warranty is half for rear tires for staggered setup. So if 70K is for front, your rear with be 35K. Some void mileage warranty all together if you don't rotate tires on regular basis..read the fine prints! You can use many available "tire size calculators"..here i've done it for you.

You should be OK with 255 in the rears. Don't know what that size will do to your stability control system.

For vehicles equipped with staggered size fitments (different tire sizes front and rear), the mileage warranty for the rear tires will be 50% of the stated mileage warranty for that line.

That link posted by fellow member @jdpdata is a great resource...You will not have any issues running that size tire on your rears. Lately seeing lots of folks are trying to "square" their setup so they can avoid buying different tire sizes on their staggered f sport wheels...

The other option would be to square your entire setup by going 245/40/19 all around. See this thread: https://www.clublexus.com/forums/gs-...-06-combo.html
