Rim sizes - August 2008 There are probably 10 different 15" Chrysler rear drive wheels with a 4 1/2" bolt circle...maybe more. Different widths, and offset/backspacing. You probably should have found a tire store that would have let you mount one to see if you liked "the look" and to see if there was any interference. Also, you might like the look of the 205 75 15 tire on that car instead of the 205 70 15. The 205 70 has A LOT less sidewall height than the original tires. A 205 75 is closer. That is if you are going for a stock sort of look. Dick Steinkamp Bellingham, WA The key point here is WHAT Mopar wheel is it? I used the '77-'78 Chrysler Cordoba wheels with 0057 stamped next to the valve stem on '64 Daytonas, they have the anti-spin wheel cover humps on both sides of the valve stem as most do. These are only 5 1/2" wide but that's a full 1 in. more than stock for '59 & on Studes. and are perfect as they were designed to run P215X75R15 or P225X70R15 tires and have no backside clearance problems with Stock '64 Stude. Dics. brakes. They will be slightly noticeable as to fender clearance, but not likely to hit with P205's. Everyone has their preferred "look" and choices, and I respect that, BUT, you will not see me driving a Stude. with more than 6" wide rims on the front, because they do not belong there, look right, align right, drive right or anything else! If for no other reason, the proper size tires will not properly "fit" 6 in. plus rims, as in sidewall flex! And don't even talk to me about those 16" plus "Wagon wheels" that may look OK on a Pimp's Suburban, but not on a 50's-'60's car! StudeRich Studebakers Northwest Ferndale, WA
