How many physicists do you think come here? :D

I think it really depends on many factors. For example, the type of the asphalt. Asphalts don't have same ingredients all. Or the type of the tire you use as well as the ingredients of the water on the asphalt.

Therefore, giving an exact and accurate number is not possible.

Thanks, Hamed, for your serious answer. To the other comic geniuses here, well har har har. You are sooo funny. The tire salesman knows nothing but what tires to sell you. He is no help. This study is designed to possibly save a life. All asphalt roads that are not new have about the same coefficient of friction. Most tires with good tread have about the same c of f. All I need are a couple of numbers.

Technically the coefficients of friction for wet asphalt versus dry asphalt without any puddles or standing water is "B.ad"

I'd be asking that of a tire salesman instead of a physicist.

Are you talking of the human body sliding along the road at 70 MPH after a tire blows on your motorcycle----it burns bad...

That's the day you wished the asphalt was wet.
