They are Falkens and I've already told him they are going to stick out and look retarded, but he won't listen.

To do it right requires mini tubs, relocated shock mounts, notched control arms, and cutting the fender lips. Good luck.

lol that is so redneck.

The only correct way to do it is to mini tub the car and get some serious offset wheels in the rear and relocat the shocks. Otherwise it looks like a mexican car.

What wheels and offset are you running with the 295's you currently have on your car?

Here are some pics of my car about a year and a half ago with 315 BFG's on the stock 17s. They barely fit, and they looked a little funny, but they didn't stick out. I think if you got a 10in wide rim that had the same offset, you'd be able to run them with very little modifications.

Wow! a 315 on a 17x8 wheel

It does appear to fit OK though, Did you have to do any massaging to get them to fit?

LOL....massaging....It was like forcing a golfball through a garden hose. It took 4 guys just to mount each tire. They didn't want to go on at all. They did fit however and drive pretty well, but they wore a little funny. I'd say on a 9 or 10in rim they would fit pretty good.
