General idea is 100 lbs. on the truck is .1 in the quarter mile.
Rotational weight is considered about 4:1 vs. static weight.

So if you drop 20 lbs a tire you are effectively dropping 320 from the whole truck. On paper that gets you about .3-.4 in the quarter mile.

This is all general info and has proven overall to be fairly accurate, but there are millions of factors and the D/A can effect your time by .3-.5 easily.
