26+11.50 et streets

[crazygn]

I run a set of et streets that are 26+11.50+15 and iam trying to see what my around about trap speed is but i need to know the tire dia. It say 26" but when i use a tape next to it they are more like 25" tall. Why is this, do they get taller when flying down the 1/4 mile.

i found that if it is 25" tall then my trap is about 110-112 mph , but if they are 26"tall then my trap will be more like 115-117mph.

thanks
