hi, I always measure cir on my slicks, if one is less, its aired up higher and set in hot sun so it will grow and stretch to same as the other tire. I have done this on every brand of slick there is. the tire will maintain its size afterwards.the toyo is a very good tire,
I also vary my burnout depending on track temp. if it's cooler, then bit longer. tire still works the same. thats why some guys shoot track temp , for that very reason.just food for thought.
