tow vehicle

The rubber smell has been noted for many years by many people towing vehicles, and the logical explanation is that the rubber particles that constantly wear off the thousands of tires that use the highways stick to your toad's exhaust system as it passes over them, likely stirred up by the coach. When the toad is then started, it takes a few minutes for the accumulated rubber to burn off. In normal operation, the particles burn off as fast as they hit the pipes, making any smell virtually unnoticeable. I've noticed the same smell over the years towing multiple vehicles, but I've also noticed that the smell rarely occurs when the bulk of the towing trip has been on wet roads during or right after a rain or snow storm.
