SanMarMor: Correction C Bears has the TPMS I use the old gauge myself. I was merely pointing out not to put all your trust in the valve stems. On the compressor note I bought the Harbour Freight six gallon 150 PSI to be able if needed to pump those high pressure Good Years. The other reason is when I go south for the winter I lower the pressure to 40 PSI on the duals on the truck after I get there, and bringing them back up to 65 PSI when time to haul the trailer was a painful deal with the one gallon 100PSI compressor. Getting those 125 PSI trailer tires made it easy to justify getting the larger compressor which works well for both sets of tires . If you watch the Harbour Freight adds the $139.00 six gallon compressor was on for $99.00. It works well and weighs about 40 lbs.
