i got a good deal on a set of 15x12 welds so i bought them and used 295's these had 6 in backspace and the problem i had was they rubbed the bottom of the shock mounts. the mounts with that much backspaing actually set the shock mount about 1 1/2 in inside the wheel grinded slightly and they worked and looked great . did do full notch and trimmed lip a tad. like everyone else, you would be happier with 10's
