You're asking a question which has many answers depending on different variables. Not all tires of the same advertised size are really the same size. For instance.... you can easily and safely fit a Nitto 315/35/17 on the stock 17X9 rim, yet the Goodyear 315/35/17 is too wide and will rub. Strange huh? If you do an advanced search within the SVT Tech forum you will find this subject of what fits what and what requires some minor modifications if you do a quick search. You can increase the clearence for wide tires by adding a set of rounded IRS sub-frame bolts or by adding a 3/8-inch spacer.
