On third set of tires on our 2011 Cyclone (3 axle). The originals were shot within a few hundred miles; we put Carlisle on it and was very happy. Had one tire with a slow leak, needed 20# after about a week.
Just put new tires on. Told tire guy to put new valve stem in that one; presumed it was the issue. Have steel valve stems and then the 507 TPMS screw-on monitors. Anyway..
New tires were fine, but went to head out on second trip with them and the monitor was squawking, we had a flat. It was the slow-leak tire, but they were new tires and this rim was on a new position.
Figured it was coincidence being the same as before.
Aired it up and completed the trip, it was leaking about 5PSI/hour, so we would stop and air it up every few hours.
At camp, checked with with soapy water and couldn't find the leak, was presuming it would be valve stem since we did not find anything stuck in the tire.
No luck finding the leak.
Took the tire off and over to our tire guy and had him check it out.
A couple minutes with soapy water and he found the spot.
It was leaking in the center of the rim. 4 inches over from the valve stem, center of the rim (center of the cross section). That explains the slow leak on the last set of tires. New tires have a bit more pressure, so they leak faster.
These are HWT 8 lug, 16" aluminum "split spoke". Have a new rim ordered.
First time I've seen a rim leak like this, it's obviously a poor/failed casting.
