Ok full disclosure, I'm not sure I fully understand what all the various colored boxes are telling me in the proTyres app. I was about to post a screenshot to see if I could get some help, but I see now it is really all explained on the download page for the app. Now I just need to start paying more attention to see how the tire temps (core vs. surface for instance) work together. There is a lot to learn!
I know some of the theory of tire temps across the surface from my real life experience, but I actually haven't really had much luck in sims using camber to adjust the inside-to-outside temps like I would on a real car. I suspect it's just something I'm misunderstanding.
