I lost one on the way home from paragon last weekend. While I can't be sure why, I kinda atribute it to a leaking valve stem... As I almost lost one on the other side due to dry rotted stem on the way up..
Are there any good places in Raleigh that carry/order Goodyears?
FWIW - My trailer was bought used with newer tires, I should have check that the stems were newer also...
Also, how many miles can one expect to put on a set of trailer tires?
