I'm looking for some bias ply white wall tires that will fit my stock split Firestone AR rims. I believe these are not the 'widowmaker' style rims, and estimates to have them dismounted and remounted are around $30 each go around. $240 for labor seems like a lot considering I might go with a bed mounted spare (now $300). These rims need to be restored, so I'm thinking of dismounting the tires myself...sawsall? Anyone seen 17x7.5 whites? Where? Advice?
