burnt rubber smell??

[rolnovru]

While driving home yesterday in my 1999 34' rexhall class a motorhome, I noticed on a few occasions a burnt rubber smell. I looked over the tires and engine and do not see anything standing out. Any ideas?? I was not stopping or on the brakes at all. I was actually had the cruise control on at 60. I looked at the belt and it looked fine nor did I here it squeal at all. The smell would come on and then slowly dissipate out. It happened a couple of times. I looked around to see if there were any tractor trailers around, as they seem to always smell of burnt rubber. It was just me on the road. Thanks

could be a brake caliper dragging a bit, next time you smell it stop touch each rim see if ones really hot.

It more likely bits of rubber off the road getting onto the muffler.

Were you towing perhaps and there have been some reports of this phenomenon that seems to be coming from the toad and with no real answers, as to why.

I would suspect the alternator belt or the air conditioning compressor belt if they are different. The belt may be the source of the smell, but there may be an issue with the alternator or compressor causing the belt to get hot. Belts can slip without squealing.

Another possibility is an intermittent short in some wiring and you are smelling the insulation smoldering.

Or a hose/wiring bouncing and touching the exhaust somewhere up front since you smell it in the driving area.
