I recently picked up a 70 Road Runner with Rallye wheels but the date codes were about 17 years old. They were the current size that I see often of 15x7 front and 15x8 rear wheels with p215 in front and p275 tires in rear -- I loved the ride and initially figured I'd just get Coopers or BFGs since I didn't feel comfortable on 17 year old tires for long cruises.
But, I really wanted a stock appearance since I used to ride on Polyglas back in the day (and then Concordes when I was broke and needed new tires). I searched and found the Coker Firestone Wide Ovals that would fit the Rallyes since they do make 15 inch radials in Wide Oval Radials. But after 40 years of staring at pictures that say Goodyear Polyglas, I just could not put Firestones on a 70 RR.
After decoding the build sheet, it said that it had 14x5.5 Road Wheels. So, after a few weeks, I got some 14x6 Road Wheels from another forum member and ordered the Polyglas Radials from Jim Miner at Heartland Tire.
It has REALLY taken me a while to get used to the smaller (original) size, but it rides great and looks the way I remember when these were my daily drivers. I wanted to share in case anyone else is on the fence about trying out these tires. It drives and responds about as well as you would expect with stock suspension and radials vs bias ply, so I'm very happy with the results.
