I have a 84 half ton Chevy Suburban 2WD with nice wheels and I want to put them on my 92 GMC Jimmy 4X4, they both have 15 wheels now and the same size tire. The wheels on my Burban are aftermarket and have a large oval shaped bore for the lugs, I believe they are made by Eagle wheels. Will they bith switch out or will one just switch for one??? Need some help before I go spend the $$$ to switch things all around,,Thanks!
The lug bolt pattern on your Suburban is 5 on 5 and the bolt pattern on your Jimmy is 5 on 4.75. It sounds like the wheels on the Suburban are multi fit and require shank type lug nuts with washers. If the bolt pattern on the Suburban wheels is slotted small enough then they will fit on the Jimmy. The major difference will be in the offset. The Jimmy has a positive offset wheel (higher backspace) and the Suburban wheel will not be a positive offset (smaller backspace). This will cause the aftermarket wheels to stick out slightly on the Jimmy. The Jimmy wheels will not fit on the Suburban.
measure the backspacing on the rim from each truck. You will require a larger backspacing to fit the newer truck. On my 89 Blazer, the backspacing needs to be at minimum 4, this should be the same for your jimmy.
