I agree with JC too. I stop and check my tires every 5 miles just to be sure.
Mmmmm...another electronic gadget. I've driven heavy stuff for 40 yrs and have always manually kept track of my tires, just keep doing it the way you've been doing it.
Gary tire didn't drag it was turning just like the others. It didn't lose any air either so a monitor wouldn't have told me anything. We were getting ready to pull into Patterson to have lunch and do our tire check when we got lite up by CHP. He said he had never seen one this bad and still holding air. We have two cameras BTW.LOL
How did we ever drive along without all this technology like TPMS, cameras, cruise control, anti lock brakes, etc, ? What amazes me is that here we are in the 21st century still driving on pneumatic tires that go flat at the mere sight of a stray nail...At the next bus rally, I'll have my skid steer solid rubber tires mounted on my bus...JC
