Glad you are okay @redbaron! Keep safe out there.

@redbaron obviously you had a sidewall failure. My tag tires had cupping and an odd wear pattern before replaced and it makes me think of the stress and forces put on these tires when in reverse AND turning. I think any type of turn in reverse is dragging these tires putting forces on them (lateral) that they are not designed for.

As we know "tag dump" is not "tag raise" it's just letting the air out of those bags, how completely who knows and how long do we wait as drivers before putting it in reverse and going in motion? Airbags take time to deflate, I bet most of us never wait long enough for that to occur.

With HWH Active Air, I had to ask for tag dump to be programmed in, it is not the default. With your system, do you know if in fact your tag is dumping? Regardless, with the weight on your coach and higher, I really saw it with King Aires when at Newmar, they have tremendous aft weight it appears. The side force has to be pretty bad on those tag axle tires. Something to be aware of, both tag dumping or not, and making any turns when in reverse.

For those of use who don't know, can you explain "tag dump" please?

For those of us with a Freightliner Chassis, when we put the Allison in reverse, we should wait a few seconds until we start backing up. This allows the tag airbag to deflate, and the tag tire will steer more easily.

The tires were inspected 2 days prior and 1100 miles prior. All 8 tires inspected by southern tire mart. They suspected another tire, but did not see any visible wear, damage, or checking.

What they did not do is remove and balance as I was not willing to spend money on a rear tire that showed no issues.

That was another mistake. The wear you see and further sidewalk happened after the explosion that was in the tread about 3 inches from sidewalk. When the tire exploded, it stopped spinning and I drug it across lanes before it started to spin and walk off. I then slow drove it until it was evident I was about to be on a rim, and stopped.

None of the things we where told to watch out for where evident except for the shimmy. That is something I knew was a problem but didn’t realize all tires play a role in. Next time I will spend the extra 2 hours to get all balanced and road force tested.

@redbaron , I also use Southern Tire Mart, one in Shertz or the one in Buda, TX. I'm not aware that either store does the road force test.
