Well I just had my first blowout, 40' Monaco diesel. This was a 275-70-22.5 Hancook that I put on in February 2012. I really thought they would last a little longer than this so I wonder if I should ...
SmartTire monitoring tells you if the tires get hot. Once I got an alert that front tire was overheating.. I slowed down from 65mph to 30mph and watched the tire cool down before going again. I am pretty sure I would have blown out.. the temp was running away to the upside.
also, I only use michelin tires.. FMCA discount is very good.. I waited 3 months when they were on backorder.
