Nice Day for a Drive

[Russ T. Fender]

Don't know if they are interchangeable but I bet they are.  Those Allstate Safety Tread tires are indestructible.  I have them on my 30-U and they are at least 40 years old.  Still pliable and no sidewall cracks.  Mine are 4.75/5.00X19 which I believe is the correct size but I'd try running what you have if you have them for all four wheels before springing for replacement tires.  The larger tire size may make steering a bit harder with more rubber  on the road but as long as they clear the fenders I would give them a try.

The wheels are in great shape but the tires are shot. Bald to little thread.
Definitely will need new tires.  Too bad, although those tires are really big.
