Topic: What radial size on 14x7 Steel Wheels

[J_Speegle]

I have Firestone supreme P215/70R-14s, needs bigger tires for sure,...........

But the OP asked for "What radial tire best matches the F-70 WSW Polyglas tire that came on the 1970 14x7 steel wheels??" 

14" and even 15" are getting harder and harder to find In a couple of years the original style reproductions may be your only choice. The challenge gets compounded when you ask for WSW.

Allot of what is still available today is Chinese made tires - any plenty of those companies have had problems lately according to the newspaper reports . 

Just went through a similar exercise and these sights might help
