Re: Contact Area and its Relation to Friction?

Recently we did a tire traction experiment to try to answer some of these same questions. Attached you will find our results. I present these only for your enjoyment and not as an endorsement for any particular tire. Since these were tires we had on hand, some were well worn, some were new.

The results were not what I expected. I was surprised at the performance of the large knobby tire. Perhaps this could be attributed to oxidation on the surface of the tire that made it less sticky.

We have not paid too much attention to the air pressure in our tires in the past. We will now.
