These wheels all created a slow pinhole leak at the end of a weld and would take a number of hours to go down. After driving for 4 or 5 hours we would stop for the day or have get gas and I would check tires. Shure enough a tire was going down. At one point I had two at the same time go flat overnight while in a RV park in Junction, Texas. Fortunately the RV park owner brought his compressor over and pumped up tires and I got to a small tire shop in that little berg. I feel fortunate that we were always able to get to a shop or get pumped up long enough to find a shop close. All of the brakes were with a 20 day period March 20th to May 10th this past two months.
