Best Tire/Wheel/Price Combo?

For best help try a place that sells tires. I mount tires at Sam's Club, college student, and I've been looking through the books for the best combo for my 2001 mustang gt. It all depends on the tire width your looking for, I currently have 265/35r18 on chrome mach 1 wheels with a width of 9" the book tells me that I can go up to 275/35r18 on that rim. Sam's sells some BF goodrich's for about 150.00 give or take depending on the size, and yes they are street legal, as long as a tire has tread it is street legal. These tires barely have tread! I was also reading around that the mustang 99-04 gt can fit 300's on the rear, I was thinking of ordering some tires and finding out personally, I just need to find a rim wide enough. The gt can aslo go up to a 275/35r18 in the front and not rub, any thing bigger then that will require spacers or better yet, a new k-member. As for the bolt pattern and size 5 lug not sure on the size might just want to try a universal rim. Some one else might know. I was going to order my rims through summit, with there website you can just type in the make and model, and it lists every thing for that car out of there catalog, very helpful. http://summitracing.com/
