    M&H recommends a 13.0" wide wheel for that tire. Its also 28" diameter, meaning you better be running at least 4.10 gears, or is going to really slow you down. 28" tires make sense on 800+HP setups.

    The section width is 13.8". That's compared to 12.4" on my 315/35-17 DR's. I can't see how you could keep the tire even barely under the fender and fit it in the wheel well. I've got a fraction of an inch clearance to hammered inside fenders. The 345 is going to require a mini-tub because it needs at least 1.4" more clearance than the location of the stock inner fenders, and requires offseting the LCA at least 1", if not more.

        go 295 or a 305. Keep in mind chances are you can run a 315 tire. Fred would know.

            A 315/45-18 is a 29" tire. If you can possibly shoehorn it into the wheel opening, its going to slow the car down even more... may require 4.56 gears.

                Its best to stay with a tire with an outside diameter close to the tires that came on the car from the factory. The WS6 and SS's (coupes only) had the same diameter Z-rated tires - 275/40-17 (25.7").

                Non WS6 or SS had either 235/55-16's (26.1") or 245/50-16 (25.7") with the QLC Z-rated tire package. Should be a size indicated on the sticker on the door, or look for "QLC" on the build code tag.
