Well, I took a hard look at the tires after the last blowout. The mechanic thought they should be good to go. So I went.
In Moab, the mechanic that put my new front hubs on thought the tires were good to go. So I went.
I shouldn’t have “went”.
I currently sit beside the road, dripping antifreeze, thankfully off the roadway, with blowout #2. I wasn’t so lucky this time, as it took out some coolant hoses and some “protective” baffles that were to protect the hoses. It also took out a little wiring that is non-critical, except that I cannot dump tanks until I fix it. Also took out a piece of leveling jack, that appears to be repairable. And finally, it took out the drain to the shower, which also was behind a “protective panel”.
I was picking up pieces off the highway for 5 minutes after I found a place to get off the road. First priority is always try to get to, or a safe zone, or make one with reflectors, cones, etc. Second is to always quickly remove the debris field from the roadway. I had left leveler springs the size of shock absorbers on the roadway.
Road service out of Monticello, UT is supposed to be here early tomorrow. First said this eve, but called back and said he had to wait for the tire. I suspect that something like his wife wanting him home tonight.
My current location:
The debris I let behind (not including rubber, and stuff I could not locate):
And to top it all off, I made a side trip to Monument Valley, just to discover that I had been here before, and forgot!
I am developing a theory on this. Both blowouts inside rear dual. Both blowouts while climbing a long steep grade at full throttle, in 4th, perhaps 3rd gear. The inside tires are the ones that get hottest. When going up a steep grade at full throttle, the tires are transfereing the maximum torque that the drive train can deliver. These two conditions mean max stress on the tires.
