[flathead4848]

Hi; New boy on the block. I have a 89 suburban 1500 4x4, and I want to take off the 15in wheels and put on 16in wheels because of the cost of the tires . I need to know what wheels will fit. I have read that Toyota wheels will work. but will use what ever will fit. I have a set of tires on my 93 2500 chevy ,its got no motor. I put that motor in the sub. I sure do need some help. Thanks to All. flathead4848
