The two times we smelled hot rubber inside the coach....both ended in blown tires. The last time, being gun shy from the first time, we smelled hot rubber and pulled off the road. I checked all tires/rims and nothing felt extraordinarily hot, or even warm. About 10 more miles up the road, the tread on a brand new tire separated and completely came off the tire......not a good thing...... Get a tire professional to check all your tires closely for indications of failure, and replace it/them if they find anything.
