: 275/35/R18 on all 4 corners

So I keep seeing that 275's wont fit on the front of my 2004. Is that because the fenders rub or that the tires won't get to full lock before the tires rub?

My daily driver tires are stock size, but I run tack days with track only tires.

If I am running a 1" lowered vehicle on track tires I can run a 35series tire to shorten the side wall and should not have fender clearance issues - right? has anyone confirmed that this works?

Additionally, these are track only, so I will live with no "lock to lock" steering capability.

Please let me know if there is another issue that I should be looking at

I only have experience running 275/35/18s on all four corners on the track at stock ride height. They worked. Haven't made it there since I put coilovers on though.

There are a number of us running the 18x9" Team Dynamics wheels, and I think just about everyone uses 275/35s on those. I've run a couple of different sets - Hankook Z214s and Grand Am Continental take-offs - without issue. As you said, the reduced diameter seems to do the trick. I'm lowered ~1" or so on KW coilovers, maybe a bit more in the rear.

Here's a couple on the GAC scrubs:

It's probably an optical illusion, but that front driver's side tire looks like the rim is off the tire in that pic.


These pics are awesome!

Wish my V stayed that flat in the corner. One day.

It's pretty amazing how much the tires deform mid-corner. That's at Oak Tree @ VIR, so I'm only going about 45mph there.

Oh, and that first pic is my mouse pad here at work. :p

I have a video at Fontana of my Buddy's cobalt SS turbo. We both had about the same cars... You can see that tire flexing like a jock in front of a cheerleader contest. Its nuts. I thought for sure it was going to come off the wheel when I was watching it

Been running 275/35s on all four corners for years w/ eibachs (lowered in the front about 1.5"), with no rubbing issues on stock rims. It mostly depends on the tire. Falken Azinis rt-615's (or 615k's) fit fine.

On the track I wouldn't run 275's without wider rims, as you would have worse performance. I run 245 hoosiers on stock rims at the track.
