Tire date update

The other day I posted that out of curiousity I was trying to find out how old the tires on my old truck might be. I know they are ancient. They are all Rayon and the cords that are showing in a couple are cotton. The odd sized one (6.00-20) has worn through all of the cords many years back so there's no telling on it. Someone wanted some pictures as a reference so I took some. There is one rear that I am certain was WW 2 surplus. The duals aren't on it - those tires are even worse and would never hold air! Don't worry - I don't drive her more than a mile from home on these old tires!

I put descriptions on the pics but they didn't take. The first one is the smaller front tire - a Kelly Springfield. It is actually stamped Springfield Kelly on the side. I assume that's the same company. The second one is the other steer tire - a Goodrich in pretty good shape considering. The third one is a rear. I can't recall the maker but the "belting" showing is all cotton. The last one is the other rear and I think military. It has Special Service stamped on the side and some sort of logo. I think it's a crest with USA in it. It it was dark and I couldn't quite tell. It's a miracle the old girl has made it with that missing chunk on the tread of that rear tire!

The last picture is in fact a military tread tire. I have a few of those and I even have a couple of those 5 hole rims

Hum ? I'd of guessed a 1 year old China tire from how bad of shape they are. LOL.
Amazing how tires used to hold up and now they do not. Parents have a 2 wheel trailer that still has the original tires from 1977 ! Still can haul with it on the roads as Niece borrowed it. Last year I told them might be fine local on back roads but I would not go on a hiway with it. They don't look bad and have full tread just I know how old they are !

Old, do you have any useable 6.50-20 or 7.00-20 tires around?

Don't know of any 6:50 or 7:00 on hand but I think I have some 7:50x20s around

I have 4 700-20. Two have tread and two are smooth.
