We're been travelling the better part of a year without any trouble and we haven't added any extra weight. It would be weird for them to go now all of a sudden. I'll check the tire code and see the actual age of the tire.
It's possible that when the one tire went and I put on the spare that we overloaded the other side. That tire blew out, I heard it go. My tires are E rated buy my spare was D rated. When I bought new tires I had them use the best of my old ones (an older D rated Towmax) as my spare. I guess that could have shifted weight over to the other side.
I thought I should be at 70psi, but I looked and it seems they should be around 85 (although I've been driving at 70 for a long time).
I'll need to weigh again. We've been out for a long while and we've probably bought a few things, some games, some clothes, etc, etc over the last year that could have bumped us up. I'll go through a weigh station.
Right now I need to get these tires fixed, we're stuck in Summerton, SC right now. I can't go anywhere. I'm just afraid of spending a bunch of money on new tires and then blowing them right out again when I hit the road.
The road WAS very rough. It's I-95 heading north from the SC border. I told my wife it was weird how much rubber was on the road. It looks like a lot of tires on the side of the road as we're driving, a lot more than usual. It was interstate so it's nothing crazy, no dirt roads or anything, but for an interstate it was a pretty rough ride. I suppose that's possible also.
