The fronts are 15x7's and the rears are 15x10's the rear tires are 295/55r15 MT SS Drag Radials. I bought the wheels 8 years ago I can't remember the back spacing but I can look around and try to figure it out for you. What ever it is they work perfect with those tires. Im running Caltracs mono leafs in the stock location with caltracs bars. The tire has about 1/4" clearance with the spring.
