I have notice that consistently my inside duals show a higher temp than the outside duals sometimes as much as 6-10 degrees. My insides duals have never run more than 10-12 degrees above the outside tires. Question, are you duals all inflated to the same pressure? The only time that my tire temps got near the 190 temp you mentioned was when I was driving fast -- near 70+ in the desert (outside temp about 100). When I slowed down to lower 60s, the tire temps also dropped 10+ degrees.

Subject: Smart Tire Hi Temp Warning
Got Stuck in Bumper to Bumper Downhill crawl off of Mt. Hood, Oregon yesterday afternoon on westbound Hwy 26. I had the transmission locked into 3rd gear but had to occasionlly use my brakes, even thought most of the time I was in 1st or 2nd gear with the exhaust brake on. Near the bottom of the very long grade the Smart Tire monitor started Beeping and a Red Light flashed. As I scrolled through the tire temps. I saw the Driver's inside Tire at 190 degrees, it rose to 194. I stopped and felt all of the tires. None were abnornally Hot to the touch and Smart Tire indicated the pressures a little high because of the high temps. I thought of a defective sensor. Many miles down the road the temp dropped to 172 and red lignt went out. The other inside rear sensor was at 172. Eventualyy both dropped to 154 for the duration on our trip home to Milwaukie. I thought the cause must have been hot brakes that trasferred the heat from the brake drums into the inside steel rims. I've noticed that the inside rear tires always run 30 to 40 degrees higher than the outside tires, even on the open road with no brake usage for hours. I've check tire pressues manually with a Good gauge and Smart tire readings are relativly close to manual gauge readings. Anyone else have similiar expereinces? Thanks

I believe you are running your air pressure to low. We never go above 135 degrees and thats even at 90 mph, which my wife did once in Arizona while I was a sleep. The speed showed up on a computer runoff we did with Cat. We run our tires at 110 on the front and 105 on the rear. This is about 15 pounds over the tire pressure chart but I like the cool ride and the margin of safety. The rides not as great but this is a mh and safety is our most important issue. CCs ride good at almost any air pressure. I do not want to ride in a coach that is running 190 degrees on the Smart tire. It's not good for the tires.
