When I had a flat on the big trailer 4 hours from home, I called US Rider and reported the need…and immediately hung up and started calling around to local service providers, too. I was on the side of I 65 for over an hour in the late summer heat. I couldn’t find anyone close, nor could USR. I cannot physically manhandle those huge tires, I needed help and the driver’s side of I 65 is nowhere I’m willing to be, down on my knees, wrestling a tire.
A good Samaritan stopped and changed my tire for me. I gave him $40 cash (all I had with me) and thanked him a hundred times. Have the right tools with you, including tire chocks, a good spare, tools that fit, a Trailer Aid to drive up on (worth it’s weight in gold). Take a good phone charger and go.
I have kept US rider for 15 years or so and used them maybe 6 times total? Only half of those involving the truck and trailer. I wouldn’t shell out the $ for one 90 mile trip
