Someone mentioned in another thread that if i run these tires i should use 10mm spacers ( assuming i want spacers in general of course). Someone else posted using 15mm and 20mm spacers with the stock 19s and stock tires but i want to make sure that since i got wider tires now i dont rub. Thanks in advanced

I would strongly recommend against installing those tire sizes on the OEM wheels, they are too wide for those wheel widths and it is outside of the manufacturer's safety specs.

He's exactly RIGHT! Please don't do it. However, 265/35/19 on the back (8.5" rims), even though it's slightly out of manufacturer's recommendations would, IMO, be OK. Or 255/40/19 is also OK and within specs. The fronts, 245/35/19 are OK on the stock 8" rim.

oh man im already running 275 on the rears... thought i found alot of people on this board that was doing that... what could happen with this setup?

The tires can very easily explode and they can roll right off the rim if you corner to aggressively.

Damnit. Well i just order my 245/35/19s for the front. I guess i can throw those on to the back then. Man i really must of misunderstood what someone told me. Might as well order another pair of 225/35/19s for the front. Whats the largest tire size combo people run on the 19s?

Not sure on the OEM 19s, but someone is running 315 on a 19x12

See my post above for size information. Don't run the 245/35/19s on the back, they will have an outer diameter that is too small. The same with 225/35/19 in front. Remember 225/40/19, and 245/40/19 are stock sizes.

u should keep the tires and buy new wheels!

The 245/35/19's are fine for the front, those are still within the tire specs for width, its the rears that are the problem. You'll likely be okay, but the bulge in the tire will hurt your performance probably more than help it. 255/40/19 is the widest I would go in the rear

275's on a 8.5" rim are fine.

Ummm.... No!!!

the 245 on the fronts are ok thats what i have on my stock 19's

You can run 245's front and rear without any issues, they'll give your car
good balance. I'm using the 275's on 10.5" rims so using them on OEM
size rim just isn't practicle/smart!

my friend has been running 275/35's on the rear of his z on 19x8.5 volks for over two years and a few autocrosses, no tire explosions there

275's prob arent needed, but they will work.
