The numbers in the oval are 2613801. The tires look like they could be new! I have had the truck for about 2 1/2 years. I purchased from Larry Sparks. He is a bluegrass singer for the last 40+ years in case you haven't heard his name before. It was kept in his barn and he used it to teach his son how to drive!
There are no cracks on the side walls at all. I think I will give them a shot. I just drove it for the first time with brakes. The couple of times before that it didn't have any brakes! Tires seem to be round and in good shape!
