The back right tire (all the tires on the car are 190/70R14s) on the 1984 300DT has a nail in it and the tire looks battle worn. I still need to replace some major front end components (LCA bushings, lower ball joints, tie rod ends, etc.) so the front end can be aligned properly.

Since I'm slightly financially embarrassed at the moment, I have to collect the front end parts as I can afford them. That said, I'm thinking of changing out all four tires with a set of Michelin 205/70R14s I have already mounted on mercedes wheels OR just change out the rear tires with the 205/70R14s. Any thoughts?
