AWAG:
Every time it goes sideways in the burnout box, it's been the circumference of the tires were different for me. I would recheck them again. If you over inflated one to stretch it to match the other, I've found that they eventually shrink back to their original size over time.

JEFF/21C:
borrow scales form a circle track friend and see if you have a pre-load bias. inflating tires and putting them in the sun will make them grow,be careful people have been injured when tires have exploded or rims coming a part when over inflated

wideopen231:
I have found that shrinking the biggest tire works better than stretching small tire. I let all of air out and then place heater in front of tire. I rotate avery few minutes till tire is ptetty warm then let sit. When I air tire back up most of time it is 1/2 to 3/4" smaller

wideopen231:
May find some scales around a pro stock team or maybe one chassis builder I know. Believe it or not I do not know any round trackers. That from a guy living and born in NC,home of nascar.LOL
