---------Toyo's------- BFG's
diam.----37.1"---------34.5"
circum.--116.553"-----108.835"--------(63360 in = 1 mile)
rev/mi.--543.615-------584.58
584.58/543.615=1.075
So, the Toyos travel 0.075 mile greater than the BFGs do in 1 mile.
So, when my speedometer says I am traveling at 60 mph, I am really going 64.5 mph.
@40 = 43.00 mph
@50 = 53.75 mph
@60 = 64.50 mph
@70 = 75.25 mph
@80 = 86.00 mph
Also, for every 13.33 miles, I am traveling 14.33 miles
1 mile saved every 13 1/3 miles.
ROOKIE,
Did you check the dates on this thread ( da !!! ) April 06 was the last entry before yours
