265/30/19 on stock 19's
 

Will they fit?

are you trying to use these for the front or rear, it'll fit, but if its for the rear its way too short, and if its for the front, its arguable that its too wide for the 8" wheel, and then you would have to run a 275/35/19 or 285/35/19 in the rear to keep some sort of stagger, which many will argue is too wide for the 8.5" wheel. Basically, that tire size has no place on a G with stock wheels

it's for the rear wheels.

The tire place said that 275/30 would be a better fit for the 8.5 rim..

any thoughts?

Best bet if you want to upsize would be to run 275/35/19's in the rear, and 245/35/19's in the front. This set up is the closest to stock in terms of overall diameter.

255/35 19 is pretty close if you want wider. Michelin, goodyear, continental, all make this size. I'm sure there are other manufacturers that make that size. I'm going with goodyear gs-d3 in that size for the year.

Yes it will and there is no downside to it either.

I run 265/35/19 Potenzas in the rears. They have a perfectly flat sidewall (no bulge). The overall diameter is about .5 inch smaller (can't even tell).

As an added bonus, you will never scratch a rim anymore. Yesterday, I got caught in a snow storm and ended up rubbing a curb for a couple of feet. NOT A SCRATCH!

Just make sure that anybody who gives you advice actually has that particular tire on their G.

I am running 265/30R19 on my rear... I can post some pic if u want...

that looks horrible, good job, you managed to increase your wheel gap while throwing off your speedometer reading :rolleyes:

That wheel gap is HUGE. You really need to lower your car now, it looks abnormal.
Are the tires a little bit under-inflated in that pic? I see a bit of bulge, I think.

i thought the tires are little flated as well....but I am running on 35psi already....

It looks alrite from an away angle....
and i will be getting a set of 275/35R19 tires along with my new rims later...
and about the speedometer reading...
Some one on this board has already said speedo is only off by 2~3mph if that matters to u....

Actually, its off by 5.5% and 1.4inches shorter than the stock size, way off is you ask me
