Default Choosing tire shore #.

Is it best to choose tire shore # based on tire wear?

Depends mostly on how high your traction level is at your track. In most cases softer tires will provide better lap times.

We run on a variety of tracks from low tration (but prepared) parking lot course to very tight permanent track. All have a max of 15 minute mains.

40 rear + 37 front is a good place to start and then start making some adjustments.. This works for me 90% of times - good and even tire wear from front to rear and enough traction at most cases, usually getting 4-5 mm wear over 30 min main on a rather low traction asphalt.

Thanks, 37f and 40r is were I have been starting os that is good news. I tried going a little softer in the back but the car seemed like it had to much grip like it did not want to roll free in the middle of the corner.

If your track has a lot of grip go with harder tire, loose conditions less grip go with softer tire...

I normally run 40 fronts and 42 rears. I try to run the hardest shore that I can based on track conditions. If I run too soft of a shore my lap times are slower because the car will not rotate.

That is what I felt just by going down on the rears. The car had plenty of grip but it just did not seem to roll free. We had the same issue on big race cars back when I was running them.
