Track Tires?


Recommended Posts

I am late on this thread and much has been covered, there is one thing I didn't see though. How the tire makes heat was covered but not how it covects that heat out?

 

I would start by saying yes to lower tire pressure making more heat through flextion. There is another side to that sword in that the tire from convecting heat though the contact patch to the road. Basically you have the heat being generated at the edges of the contact patch by flex and being convected away in the contact patch.

 

It works like a radiator on a car, by lowering pressure you are putting a bigger radiator on the tire too. You don't always get more heat by lowering tire pressure.

 

Pressure rise is a very good way to manage tire temp, 6 to 8 psi from cold to hot will put the tire in the 160-200 range. less than 6 lower pressure, more than 8 raise it.
