"RANT ON"
I know this has been beat to death BUT I have had 3 Goodyear Marathon's "loose a belt" in 300 miles.

I had one go bad 2 race's ago, Fun Ford in VA, No problem I carry 2 spares. So I thought I would check out before Mason Dixon. Yep last 2 starting to loose there belts. soo less then 3 years old about 5000 miles tread depth at least 50% and there all bad. 4th one went bad in the spring. No more Goodyears for me!!
Do yourself a favor and check you trailer tires out.
"RANT OFF"
