Wheels-Tires Anyone running 315/30/18 tires?

There have been guys with 315's, but so far nobody with ones that run wide like those tires probably do.
I think stykthyn has done it.
But he seemed to think his 315's were technically a 295 (nitto's run small).
I also think he recommends people not to try it.

I run a 275 35 18 bfg drag radial, which run a little on the wide side.
I put a panhard bar on the car to stop them from rubbing on the inside during hard cornering (which worked).
I have no room to spare anywhere. A little out and they rub the fender, no phb and the run the tub.
They are also close to the tailpipes.

Your tires are going to be roughly an inch and a half wider than mine.
Me personally, i'd return them or get ready to spend a lot of time then money making them fit and not get torn up on the first ride.

Edit: On tire rack they say the tire is 11 inches, which sounds like some BS to fit into class racing.
Also suggests a rim 11+
A 26 inch height isn't going to help either.

I stand to be corrected, but in my opinion that tire will not fit without MAJOR rubbing in a stock wheel well, including beating the inner and rolling the outer. If a regular has done it, then I'll take their word on it, but at the moment, you can put me on record as saying that's a no-go.
