I also read somewhere recently that no two tire manufacturers tires will be the same size. They all vary by some degree, so one tire company may make a 205 that fits and anothers will rub. One of the reasons buying tires online for our cars can be a crap shoot as if you guess wrong. You have to pay to send them back. It's usually best to buy your tires from a shop the first time as if they don't fit they'll usually get you to a size that will. Then you can order replacements online if you want. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrc II " Chronic Pain Hurts" -------------- Original message ---------------------- From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) > " From: Frank Swygert <farna@xxxxxxx> > " > " > " Just divide the width in millimeters by 25.4 to get inches.
