Super, I appreciate the information but at this point I'm going with it as is. But I will make sure to monitor the tires more closely to see if there's any sign of a problem.
Skipper, it was a downhill ramp as well but straight as an arrow. The only ramps I notice with speed limit signs are those that have curves. I usually set the cruise at 68 MPH and then tap it off right when I pull onto the off ramp and then decel as needed. The instant I hit the brakes to slow down, I'm sure the tire that lost the wheel skidded when the brakes were applied and then I noticed I had a brake problem. My wife was busy asking me if I heard an odd noise (probably was that wheel skidding for an instant) and I just said no because at that point I was giving everything I had to stop the rig. It was a handful but I kept it straight and I've always felt that my Ford had really good brakes which really showed that time. The trailer weighs right at 8000 loaded and I still pulled it down to Rocky Point and back without any trouble. If I'd have had my normal 1500 pounds of ATVs, bikes and camping gear in the back of the truck, it might have been another story. There's really no hills and I just drove a little different to give myself more space.
