Mainer1 and cheese1 - I too scratched my head on how to check air pressure in the rear duals easier. Considered the remote transmitters like the
Pressure Pro, but didn't like the almost $500 price tag. Also didn't like the idea of a transmitter being screwed on the valve stem that could throw the tire out of balance or loosen and let the air out of the tire. My first change was to remove the wheel covers and replace them with stainless steel inserts. They improved the looks, but made the holes in the rims even smaller. Considered the recommended
Tire Man stems. The cost of $125 also seemed a little pricey for what you were getting. Finally, looked in the phone book and did some calling around to tire shops that installed tires for the big semi's. Found a real likeable one called "Midwest Tire". He had chrome plated brass stems that he used on the "big" rigs. Charged me $1.98 each no matter what the size or twist required. He then charged me $9.95 each to install them in the rims. Two guys working, took them less than 1/2 hour. Then went to Wal-Mart and bought a
Campbell Hausfeld digital tire gauge which measures 5-99 PSI. Now I check my pressure in less than 15 minutes before I leave on a trip and then monitor the tire temperature at rest stops using the
Non-Contact Infared Laser Thermometer. Life is good. :B
