Tire sidewall separated from the rim without any incident trauma. There have been a number of reports of Dynapro AT2 tire failures on Winnebago EKKO. The temperature of the tire was alerted to be high just before the failure. I was able to be parked immediately upon that TPMs warning so an accident was avoided. The tire is a Hankook Dynapro AT2 Xtreme 215/85R/16. All tires were properly inflated and recorded correct PSI and temperatures on my TPMS before driving the 100 miles before the tire failure occurred. Outside temperatures were in the low 60s with some light rain intermittent. This was a highway drive, no back roads. NH to MA on major roadways.
