275/40x17's ...

[GT_RB]

Hi all.

I have a 2004 GT with the stock rubber on now. I'm thinking of going to the 275/40's on the front and back ... any problems with doing that on the stock rims? Any rubbing or fitment issues? Handling issues?

Anyone got pics of these on their GT?

Thanks,
RB

A lot of people do it but in reality a 275/40-17 fits best on a 9.5" wide wheel, some work great even on a 9" wide.

The stock 8" wide wheel will pinch a 275/40 some what. A case where an 8" wheel works with a 275 tire is when it's a drag radial with low tire pressure.

As far as rubbing, they will work as long as you are lowered too much.

i only have 275/40/17 on the rear and the front kept it stock size 245/45/17 and i have no rubbing issues but it does buldge out a bit

You'll probably rub in front and it would be best to go to a wider rim. Because of the balooning affect on the 8" stock wheel it will perform worse than a smaller size tire on the same wheel. I would suggest either picking up some wider wheels or go no bigger than a 255/45 tire.

I have 17x9 wheels with 275/40's. They don't rub at all even at full wheel lock. Mine don't bulge but they do fill out the rim and the wheel well. I have noticed a tendency to "railroad" with the 275's in the front and they follow EVERY groove in the road. I have BFG KDW's and they are superb for traction wet or dry.

I don't know about a stock wheel but yes the 275s fit fine on the front with a 9 wide. Yeah they do catch groves alot.

i have 275/40YR17s on my car all around. i have Konig Villian 17x9 wheels and the tires fit perfectly. you have to check with different tire brands, because the sizes are not identical. like my 275 Michelins are as wide as my buddies 315 Nittos.

Welcome Aboard!
I belive Goodyear Eagle F1 GS D3 255/40/17 in front and
275/40/17 in the back would be a great tire combo!
You shouldn't have any fitment or rubbing issues.

I have 275's on the stock rims with H&R supersport springs they dont rub but they do buldge somewhat. I will take some pics of them today when I get home from work and post them.

Went from the stockers (wheel and tire), to 275/40/17 Kumho's, NO RUBBING, I have 25 mm wheel spacers too, which really make it look great. Little wheel bulge but I sorta like that look. Keep the air pressure correct and you will like them for sure. Kumho Supra 712's

If you look at ^, you can notice the tire bulging from the rim. It also doesn't provide the maximum tire patch (wheel is too small), and is potentially unsafe. Stick with 245 or 255 width tires.

Haters everywhere.
I like tire bulge, if that's what your calling it. I hate when tires are too skinny and the rim sticks out farther than the tire. My tires are 275's on stockers and they also have "rim guard" so they are made to stick out farther than the rim. I dont' think it's too much.
Some people that have no experience with these tires on thier car will say, they will probably rub or that they are unsafe. They don't rub and they work fine. A tubular K member is unsafe too, not as strong for front end crashes. Make your own mind up and get what you want.
With all that said, next tires I buy will be a bit smaller because of price.

I actually had 275/40/17 es100 on my car before my current tires and I loved the extra protection, but it looked like ass.

I prefer tires that are flush with the rim of the wheel i.e. 245/45 on our stock 17x8 wheels.

btw, tubular kmembers are stronger than stock, and matt from mm said its fine to use it on the street. would I use it on the street? no, but everyone can make up their own minds.
