If they are 8.5, like the title says, with a +48 you may have some issues unless you make some modifications to get them to fit. 8.5's are a very tight fit on this vehicle. If they are 8, like the OP says, with a +48 offset you should be fine. (assuming you run the correct size tire and don't go too wide.) We recommend a 235/55R18 or a narrow running 245/55R18.
