The original tires on our 178 lasted just over five years, which I know is unusual. We kept them properly inflated, monitored the tread wear, and were very fortunate. They were ST205/75R14 - Load C (50psi)
In February 2020 I purchased three National Roadmax ST205/75R14 - Load D (65psi). After about 5,000 miles of use during COVID, we had a horrific blowout on I40 this past March. The tire was destroyed, and it blew off the r-pod fender. We were blessed that we were not traveling fast (about 65mph) and we were able to get safely to the side; however we ruined the wheel by driving directly on it to get to safety.
Tire dealer ordered a replacement tire under warranty. Today, headed to the NCAA baseball regionals in Fayetteville (Go Hogs!) we had another blowout - it was not the replacement tire but one of the 3 purchased in 2020, and it was on a new wheel. Fortunately we were only about 20 miles from home, and traveling around 50mph on a two lane road. I had checked the tires for proper cold pressure this morning.
Did we just get a bad batch of tires? Any recommendations as to what to purchase now? We're not interested in moving to a 15" wheel (tho' our r-pod came with axle risers).
Thanks for your insights and recommendations.
