Oh one more thing.... sorry. When you go to get these mounted... FORGET ABOUT GOING TO SEARS, FIRESTONE, TIREDISCOUNTERS or anything like that. They all want a **** load and most of them couldnt guarantee that they wouldnt scratch the wheels up -- AND THEY wanted OVER $200 to mount and balance.
IT IS A MUST to go to a speciality shops that sells big chrome aftermarket wheels/spinners and stuff. Because they deal with big rims and tires all day and have the equipment to do it right. After getting $200+ quotes from the other places, I was pleased to spend $60 on M/B at the speciality shop, and I even got to watch them do it -- so I knew if he messed it up.
Hope this helps.
