Tires are the stock Goodyear Marathons Load Range D 15" 225 75 15 running @65 psi cold.
While I don't know the specific cause of the failure, the litany of reports related to Goodyear Marathons are difficult to ignore. TPMS may be in the future as well.
Trying to get some peace of mind while on our more remote trips.
Have to wonder about tire inflation or puncture with "new" tires. People need to realize that there appears to be dealers out there who have no idea that tire inflation is important. My new Coachmen MH was delivered with every tire low and some significantly low. One was -13psi and this after I was charged a "prep" fee by the dealer.
In my experience, tires simply do not fail for no reason as if by magic. Under-inflation is most likely the cause and can result in a tire failing in 10 miles or less. Overload and low inflation will overheat the rubber which can result in belt separation after hundreds and or thousands of miles of exposure to the excess heat generated which weakens the rubber.
Manufacturing defects will usually show up very quickly as the most likely error is a mix up of materials such that components do not cure properly. This can result is components coming apart but this would usually occur very early in life. Sometimes there are external indications such as very localized wear with the tread being 1/2 worn in a smapp area or a large sidewall bubble.
TPMS can't address all the possible causes for failure but they can warn of air loss due to cut or puncture or even leaking valve.
