Contour Enthusiasts Group Archives Forums General General Theoretical Tire Question (EdwardC, I need a physics lesson here)

Ok,

I understand the area thing. So, give two tires of like construction, same tire pressure, the area of the contact patch "should" be the same. But the length and width values would be different.

And that was in my original question. Perhaps my assumption that the writers in these web articles are also keeping other variables the same and only varying the width of the tire, and hence the width of the contact patch, is incorrect.

But what really happens?
