Wasn’t really forgotten, as mentioned a couple of posts above, because it’s common knowledge that brakes can affect temperatures. However, I think that motorhomes don’t use brakes like race cars for long periods of time, except when descending mountains. Hopefully skilled motorhome drivers won’t ride brakes for long periods, because they would fade. Even when brakes get hotter than usual due to descends, the RV is likely traveling at much lower speeds, which means heat from rolling resistance of tires would be much lower. Basically there should be an offsetting effect on most descends (more braking but less average speed). I think it’s highly unlikely that a driver would ride the brakes and be traveling at high speeds at same time (like 70 MPH or so). If that were to occur, the driver would have much bigger problems than reducing tire life.
