I have a 2018 Thor Siesta 24SS which is built on a Mercedes Benz chassis. We went on a 6700 mile southern states trip back in April returning in late May. When I went out side the following day to move the mh, the front passenger tire was flat. I changed it out and took it to a local shop to repair the tire. Nothing in the tire but the rim was leaking from a weld/crack in the rim. Had to replace the rim. A few weeks later we went to Tombstone and back for 4 days (1000 miles rt). I went outside the next day[B] and the inside rear tire was flat. I again changed it out and found that the rim was leaking air from a weld/crack and had to replace that rim. I called my mh dealership to find out if they have had any complaints/issues with the rims. Nothing. I called my local mb dealership about the rim issue. Nothing. This is my 2nd mh built on a mb chassis. The one Winnebago we traded in was a 2016 Winnebago Era and we never had an issue with the rims leaking air. Anybody else out there having the same issue? When we travel I only carry enough water for the time on the road which is less than 1/3 tank. We love the Thor Siesta model.
