Last summer, we left for a four-week, 6,000 mile adventure out west. I had the TT inspected the week before we left and had some minor repairs made, so we were in good shape. The tires had plenty of tread and looked to be perfect.
At the end of our second day, traveling about 10 hours that day, we had a blowout on one of the tires. Not great, but fixable. I was able to get to the next exit, which was only 100 yards up the highway and change the tire.
You can guess what happened next. Two miles up the highway, the second tire blew out. I only carry one spare and it was used up now. AAA could not help, even though we have the RV coverage because there is no way to tow the unit with a blown tire.
Had to call a roadside tire place (in the end, AAA made it right by paying us for the roadside call. Not the tire cost, of course, but the trip and repair charge). Once changed, we went to the next exit, which luckily had a campground and a super-walmart. We were able to get the other two changed out as well as a new spare, so were on our way, only losing a half-day in the process.
What the roadside tire guy told me is that he sees this a lot. Our tires were high on tread, but were 14 years old! They had simply worn out from age sitting in the driveway. (most of our trips are local, so there is very little wear).
So the lesson is: check the dates on your tires, not just the tread wear.
