Tire sizes

Mike Kortney · 12-09-2005, 01:01 PM

I know this probably been answered in various fashions in the past but I need specific assistance on tire selection

The 2005 GTO has the 245 40zr17 stock wheels.
Big Mike mentioned that I could upgrade to a 275 40 17 and that would work fine. Is that regardless of the manufacturer or does it vary?
I have a guy who found me a couple BFG 275 40 17 but they were not sure if they would fit. Thats my first question.

second - I will be having the procharger installed within the next two weeks. With the extra HP I need wider tires with more traction to take advantage of the power (obviously). What do you guys recommend for mainly street driving (some street dragging) and a little track work? I can keep my originals for winter. I've heard Nitto's are very good (not sure if they make 275 40 17 - didn't look like it) or the BFG drag radials.

So I need to know what will realistically fit and what tire would be optimal. Please be as specific as possible
Thanks

Only use Nitto's so you dont have to roll your fender. They can be found here:

Sizes can be found here, and they DO come in stock size and 275-40's:

They spin enough to where you wont break anything but still hook hard enough to give you a good time.

Uh Mike, what the hell do you call this?

.... and this was on a 245 Nitto, I have the 275/40's on her now and love them (except for the ice....)!

bad driving! lol If you had taken it a little easier on your rear, it wouldnt have busted.

(why do my posts always sound bad?)

Hey all, Newbie here, Just to make sure, is any 275/40/17 acceptable on the GTO?
Is this size ok for front and rear?

Just the Nitto is, actually, and I wouldnt go with more than a 255-40-17 on the front.

Mike..........on the size chart, recommended wheel width is a min. of 9" for the 275-40. Will these tires still be OK on an 8' wide wheel? Hopin I dont have to get new wheels again just for the rear.

I had Nitto 555Rs in 275/40-17 on my rears for 13,000 miles with no rubbing problems and great traction! Looks and feels fine on the rear stock rim. Leave the fronts with the stock size . . .
