My 75 Road Runner 400 4 barrel came with G70-14 Polyglas
Going by my old, shredded memory, I don't recall rwl firestones on Mopars, they were usually on gm cars, but the good years were very, very common. ( and, I love your car ! )Would you happen to have your build sheet to know what your tire code is? Mine is T93 and it looks like that is going to be the GoodYear. I was hoping it was the Firestones like the original owner thought they were because those are available in steel radial design now. I plan on putting a lot of miles on Goldie next year, and I really don't want bias ply tires.
