The main things I did to this car to help with the tire wear are...
1. Put the bound up to 10, the rebound up to 9, in the rears, 6 and 5 in the front.
The next is controling wheel spin.
I did that by setting the auto to 22.
Then basicaly lengthened the first, second and third gears, while shortening the last three. I lost my settings due to another site going offline, but it realy did the trick.
