Would you trust 13 year old tires?

newer tires would be worth piece of mind.

I think older tires are made better too.

I figure number of plys make a difference. I have old 10 ply tires on my gooseneck, I pull it.

I have some 13 inch tires on the Road Toad, NO it is not on road, just roll around yard ; t heir size is like 6.75 or like E70 .... so they are how many decades old?????? still hold air and roll ! HA
