Good Morning ... back in the Texas heat. Here are my tire temperature observations from Taos to Amarillo and Amarillo to DFW.

Coming down the canyon from Taos to Espanola using the trans retarder and some brake: Front tires normally in the low 120 range or in the high teens. Drives in the high 90's to the low 100's depending on sun exposure. Tags in the 130 range. However when stopped at the various stop lights in Espanola after the the descent, the drivers tag went to 150 and the passenger to the 140's. 30 to 45 minutes later with highway driving temps were back in the 130's. Could be that the drivers side has the muffler, radiator, trans cooler (with retarder running in the 230 range) etc. contributing to heat?

From Amarillo to DFW: Front and drives same as before. Tag on the drivers side mid 130's and passenger high 120's. Although it takes and hour to two to get to these temps. However as we get into the DFW stop and go traffic, the tag temps both went into the 140's sitting at lights. At this time, we also were running the generator and you guessed it, the exhaust pipe also runs past the drivers tag. While checking into the RV park and idling the drivers tag goes to 150 and the passenger to 140's.

I wish I had paid more attention to the temps rather than just the pressures in the past. Now I am not sure if this has always been the case or if it is something new. Anyway, with highway air flow, tags can in the 130's but when stopped the temperatures climb.

Chuck: On the drives, mine were always the same temp +/- 2 degrees or occasionally 4 degrees different.

I have Prevost Nashville researching the caliper issues and if I learn anything I will let you know. We will likely stop by there on the way to or from Busapalooza in Petosky in September.
