I went to etrailer and bought 16 inch dexstar rims with 8 lugs, they are 16 by 6. I put on radials 215/85 and they just clear the tie rods without rubbing. you may want to go with this setup instead of the 15 since it will give you lower rpms owing to the taller tire. i am not sure if there is a taller tire that will fit without spacers. I am in the process of checking to see if baby moons from hunbcap mike 11 7/8 will fit, if they do then you can use the decals to put chevrolet on them otherwise you would need to use clips to put stock hubs on the dexstars. the good thing about the trailer wheels is that they work and they are not expensive
