How Do Tire Forces Relate to Temperature, Pressure, and Speed?

[cgaday]

I am trying to develop an understanding of the forces within a tire when moving.

I have been told to examine the tire as a ring of short compression springs, so I would assume each tire essentially has a spring coefficient and spring rate. I don't imagine the tire manufacturer's give this in their specs. So how would you go about determining the forces involved in a tire as it goes down the road, relating with temp, pressure, speed, road quatlity, and of course the tire stats.

Just recently I realized actually how much is going on within a vehicles tire, and have become fascinated in determining mathematically what is happening within.

Any Help would be appreciated.

semi correct...ifin you want to learn about tires see my post race car suspension..many post on tires and slip angle , coefficent of friction etc..
Nascar outlawed tire dynometers to reduce racing cost..each tire does act like a spring and there are devices used to measure deflection under load..i suggest you use the Search feature at top of the forum for research on the subjects

Read http://books.google.ca/books?id=LH8wd8im13AC&printsec=frontcover&hl=fr#v=onepage&q&f=false", Chapter 1.6. Ride Properties of Tires, p.73-87 (some pages are missing from the link, but it's free)

I looked at your race car suspension, but I am actually looking for more simplistic values, ignoring the slip angle and lateral affects of friction. More so what the tire is doing just going down the highway. With the compression forces from the road, and and centrifugal forces it is experiencing at all the other points on the tire. i searched forces on the tire, but they were not supplying the information i was looking for.

thanks jack action. that's a great source for some things I was looking for.
