I should have checked my reply. Only half of it got posted. The most relevant parts didn't get included for some reason??
Yes, I have standard rims. Three appear to be newer than the fourth, but they have been fine.
Tire size 185/80R15 or 185HR15 is pretty close to the size of original bias-ply in height and not too wide for fenders.
I bought two sets over the years. First was Federal brand, and second set was Vredestein. Diamondback uses production run tires and will customize the sidewall to your choice. I have a 2.5" whitewall added and it looks great.
The company has been great to deal with from helping to source the tires and prompt service.
I believe Coker also is a popular company, but I have not used them.
