The Tire acts as a spring, with softer tires generally offering increased grip. The aim is to have somewhat even tire temperatures across the tires.
On cars that don’t have suspension adjustment, you can adjust the balance with a change in tire pressures.
For example; take a car that is pushing or under-steering out of the corner. Lowering the front Tire Pressures and/ or raising the rear Tire Pressures, will help cure the problem.
I have some further thoughts on tire temps with regards to camber etc … more to come after further testing.
