Has anyone seen written, the max temperature tires can run without damage. When we pull in for fuel or make other stops, ours seem real warm. Holding your hand on them for a long period of time, might be of question. In my first life, we always said that probably is about 150 degrees.

THAT is a very good question. I have a infared temp gauge and I have been checking tires as I run every time I make a pit stop. I see about 130 to 145 F as a norm and have seen up to 165F when it is hot outside.
Also notice there is a definate difference between the 'sunny side and the shaded side' of the coach when I check. as much as 15 to 20 degrees is not uncommon. I do not know what the safety limit is, however I read somewhere that 180 is OK, I do not have any verifacation on that though.

Buy yourself an infrared thermometer - one that doesn't need to touch what it is measuring. I got mine from Radio Shack on sale for about $30. Check the tread temperatures whenever you stop. The 'sunny' side will be warmer than the 'shady' side, but they should all be within 10 - 15 degrees of each other. If they are not, get out your air pressure gauge! Check your toad tires too. They will be cooler, but it is the difference that is more important than the actual temperature.

Right after I bought my coach (it was and is my first motor home) I asked CC this question because my smart tire alarmed on a long descend.
They told me 200 degrees. The only time I ever come close to that limit is on a long descend or if I lose track of what I am doing and over use the service brakes. Normally running down highway I hardly ever get over 150. I'm no expert, but I think its the service brakes that create the heat. Then there is the real danger that the brakes fade when they get hot then don't work. Unhappy day when you have to use the runaway truck ramp.

According to the SmarTire Manual, the default Temperature is 176 F or 80 C. It is also the temperature the Les Schwab in JC uses when installing the system.
Paul, at Les Schwab, is the resident expert on this system and I am certain would provide the facts regarding tire temperature. The number is 541 998 3319.

Bob. Thanks for the info. I will measure my tire temps on our next trip the end of the week. FYI An ex trucker friend told me if you do a lot of braking, in the mountains, don't stop at the bottom to let your systems cool. You stand a chance of blowing tires with all the heat from the drums, so just keep rolling for the air cooling.

Ned,
Just installed new Goodyears and Smart and had no problem with temp alarm until I drove 45 miles at 45 to 50 MPH with about 10+ stops at traffic lights. My alarm went off at 190 degrees and went to 210 F degrees. I didn't know what to do so I called Goodyear and the Dealer. No one knew what temp was acceptable. We hit the Interstate and the tem dropped to about 170 degrees. I called a fellow CC owner and he gave me the info I needed. CCI Rally had a seminar in Charleston on Smart tire. They told him 200 degrees too. Heat build up from the brake drums contract with the Smart Tire sensor, so you are reading the wheel temp not the tire temp.
Inside duals tires will read the hottest and most likely to blow.
A Goodyear dealer was telling me that starting next year like 10 % of New cars will have tire monitoring systems.

ST is very accurate in telling you tire pressure after about a 15 minute warm up on the highway. I had two tires with slow leaks, ST indicated low pressure and a mechanical gauge also indicated almost the same pressure. I kept filling the tires put to no avail. I stopped in several tire shops, and three dealers. Finally I found Pete's tire in Santa Ana . They have a water tub to submerge big tires and check for leaks. Both tires had bad valve stems or valve stem extensions. After all most 14 months I now show no pressure loss after about 6 months.
Heat is low air pressure, to much braking or improper gear selection. I do not trust ST in any event other than air pressure. I have had to many false alarms.
