I'm going to be replacing the stock 235/55/17 wheels and tires on my GT.

I want to go with (4) 18" x 10" Deep Dish Chrome Bullitts and (4) 265 or 275/45/18 All Season Tires.

The size wheel and tire that I select will be based on the largest tire that will fit on the front without rubbing or running into objects in the wheel well then the back wheels and tires will end up being the same size.

My GT is not lowered, so the tire size has to fill as much of the wheel well as possible or at least as much as the stock wheels and tires do now.

When I order these things I want to order them already balanced and mounted.

I'm not concerned with the speedo, I can correct that with my SCT.

Thanks

Why would you want 10" wide wheels in the front?

I'm assuming so he can rotate the tires.

try this calculator

a 265/45/18 will be .2 inches more in diameter than the stock tire/rims

Yes this is true. I will need to rotate the tires as needed. The tires have to be the all season type. (some snow and ice). And no, I'm not putting snow ties on my GT.

What I really dont want to happen is for the tire to stick out of the wheel wells.

So, which rim and tires will safely fit under the front and still allow for as much rubber on the ground?

18x10 w/275/45/18........or..........18x9 w/265/45/18

Thanks
