Somewhere around 2003 they widened the fenders to accomodate the 20″ rims. That sounds like a bit early on them unless they were ordered with 20″ wheels then the fenders were specially added. Though we are not sure at this time. Check clearance behind the tire and the distance on the 20″ rim you are trying to use. We do think the 18″ will work, though tire selection hampers this as they are all a bit different than they are labeled. One brands 215-55-20 is not always the same size or capacity as another brands. We find large discrepancies and we are working on wheels and tires for the next model year now. Man why are they all different hieghts and widths for the same sizes? BCB
