We blew 3 tires in one trip due to misaligned torsion axles on a triple axle trailer. We got a lot of practice changing tires that weekend. Torsion axles have a nice ride but I like springs because you can do the adjustments yourself with a tape measure and a wrench. Nothing worse than being in the middle of no where (between Needles and Barstow or Barstow and Bakersfield) with a flat tire.
