5,000 miles or so, five+ years old.
As we were coming into a small town, Lindstrom, MN the trailer wagged and I asked Chryse, "is the wind blowing?" It settled down and we came to a signal, probably 1/4 mile after the wag. Luckily I could see it in the side mirror as we came to a stop.
Took advantage of Discount Tires labor day sale and have 4 fresh ones on. when they come apart, they come apart!
