They are Optima Rims. Company went out of business or bought out a couple years ago.
They are 15x9 with 4 1/8 backspace with 245/50/15 BFG Comp T/A. I had to roll front and rear fender lips and push them out a little too. I even added 1/2" spacers to the top fender supports. In the front bottom fender lip I had to bend a 3"x1" section for tire clearance. 4.5" backspace would help clearance a bunch but the 9" wide rims will still require fender rolling and still probably front bottom fender bending/cutting.
I didn't mind making all those clearance mods because I will be moving up to 17x9 rims with 275/40/17 tires. For that setup, I will need the extra room.
I've run the same 245/50/15 tires with 15x8 rallyes rims with 4.5" backspacing. That did not require fender rolling, lipping or cutting. But extremely close to rubbing on front tire to bottom front fender lip.
