Many times it's the simple solutions that return the best results. To qualify...I was a consultant to large fleets on how to buy and maintain tires, I've responded to threads on this site before on the same relative topic.
Thread topic, "Duel(should have read dual)Wheels:
Dual or single my response would and will always be the same. Eyes on Hands on.....
#1. Put all the parts and gear on you feel the need to do. But you should still physically check(not pressure, as in putting a air guage on the stem for actual pressures, but to thump the tires across the face of the tread through out your travel day. A good rule of thumb is to check each time you stop regardless of the reason. If you feel you should check pressures at the end of or the beginning of each travel day go ahead.
#2. Do not rely on TPMS or these warning systems that warn of low pressures. It only takes a minute or two to physically check them by thumping.
#3 The tool? I used to tell my clients the single most important thing to equip their tractors/trucks with is a 18" x 1 1/2" piece of steel pipe. You will be surprised after a few uses how well it works.
#4 A equal deterrent to tire failures is to use your side/west coast mirrors to monitor what's happening to either the unit your'e towing of your Class A or the like. The rule of thumb taught to truckers is every 15 seconds. That's extreme but a habit of every couple of minutes would be enough. You not only have self interest at stake but also a responsibility to others using the same roadway.
