I'm probably missing something... As usual
Seems to me that uneven tire wear is not only due to a chassis that is tweaked. Sorry to insist on this subject but I'm trying to make sense out of this.
Here's an example: I start a thirty minute race with four foams that have the same diameter and I checked the chassis for tweak and everything is OK. Everything else on the car's set up is right on the button for the track I'm racing on. After the race, the four tires are not the same diameter. Could this be because there were more left turns on the track or vice versa. And now that the tires are different in size, does this make a tweak in the chassis. If it does, why check tweak in the first place? Should I check if my chassis is tweaked before a race so this will give a good starting point to my set up even though I know the chassis will be tweaked after the race?
Does this make sense or is my brain tweaked
