I'm on the way to the tire place now to have a set of the Goodyear Endurance tires put on. Tires are one place I've never been comfortable going cheap. I had a 3 year old OEM chinese tire blow the last time out, and I'd had a feeling it was time to replace them.
I've read good things about the GY. I ran maxxis 8008 on my previous camper, and they were great, but unfortunately they don't make the size and load range I need on my current TT.
Just remember, quality tires are alot cheaper than repairing all of the damage a blown tire can do.
