I have 15" Magnum 500's on BFG's; I bought the car with those on Fred a decade ago.
I need to replace the tires simply because of age, but they don't even have 1000 miles on 'em...

I, too, faced the same problem.. I had 14" Magnums on my Charger. Currently, I want to keep the "old school" white wall look. Finding new 225/R75 14" white wall tires has become impossible, so I wanted to upsize to 15" wheels, BUT I also wanted to keep the smooth trim ring look. I ended up with 1 piece alloy wheels manufactured by Dynacorn which gave me the exact look I wanted, and they also filled up/out the wheel wells for a more aggressive stance. Hankook seems to be the manufacturer of choice for larger white walls. At some point, I'm going to want T/A's, so this info was very helpful! Pictures of the old vs new wheels are posted (I've yet to upgrade my avatar w/ showing the new wheels mounted)
