Looks like we're not going to be able to use our TPMS sensors on the new MH for now.I recall reading a few posts from people who use an infrared thermometer to get tire temp readings during "pit stops". If you do this, do you go by the same temperature standard for your external readings as the TPMS does for the inside air temp (i.e. safe is below 175f)?Also, is it correct to presume that you measure the tread temp rather than the side wall?

The temps you see from the TPMS and the IR thermometer should be in the same 'ballpark' but I doubt that they would ever totally agree. The main thing that you are looking for with either system is drastic differences in in temps on one wheel/tire. A variation on 10-15 degrees could be normal. Too many variables, sunnyside, shade, pavement temp, rain, day, night, ambient temps....... . If your checking sidewalls, do ALL sidewall, if checking tread, do ALL treads. Also check hub temps when you have the IR out. A neighbour at one campground said that a combination of the TPMS and IR thermometer saved his bacon on one trip. The TMPS showed one front tire getting hotter than the others, but still not alarming the TPMS. When he stopped to check it out, the hub was over 700 degrees, Workhouse brake problems.The main thing with either systems is to make sure that they stay within the same range (maybe 10-15 degrees). If you worry about keeping them identical, you will go crazy.Beverley and Ken

I always check both the side wall and tread.

As was said,ballpark numbers is what you will get.Look for big differencesin temps.Sunny side will just about always be hotter than shade side.When you do check the temps,hold the "gun" about the same distance away for each reading. I check mine at every stop.

I'm wanting to purchase an IR gun. What Brand would you guys suggest?Thanks,MM.

Any particular IR thermometer that you recommend?
