After we finished the conversion on the "94 Chevy Dually with the Cummins motor, I put a set of 6 commercial duty 10 ply "Thunderers" under it. Got all six for $630 total on Amazon, free shipping. I have been very happy with their ride and wear. However, about 6 months after installing them, the left front tire began leaking, and still does. If I pump it up to 73#, in 24 hrs. it will be down to 45#, but won't go much if any lower than that until I pump it back up again. I have wasted a half gallon of a strong detergent solution looking for a bubble but to no avail. I took it to a tire shop and had them put it into their water bath and even after spending a good 15 minutes looking for a bubble, none appeared. They guessed that maybe the valve stem might be leaking intermittently so they installed a new one but it made no difference. I am perplexed. Anybody got any ideas?
