My 95 Dakota 4X4 has some small 235/75/15 tires, which around here are getting increasingly difficult to find. Of course everything is going to larger 16's up to 24's on regular size rims. I do not want some oversize 33's or anything like that, I just want to be able to drive to a tire store and buy a set of tires. I don't want to spend 2 1/2 hours on the phone tracking down a tire store that has an obsolete size, and then I don't want to drive almost an hour one way just to get to the only store that has that obsolete size.

Can anyone point me to a place I can find some kind of comparison chart, for maybe a 16 in rim that fits, and the correct tire size for the gearing in the truck. Just so I can find tires easily, not to put monster tires on my truck.
