Tire selection in a Super B ie: 8 axel 140,000lbs
Im wondering if with the weight and number of tires will a lower rolling resistance tire on the drives make much difference? im looking at swapping my xdn2 24.5 tall tires with xda3 low pro 24.5. Also with the trailers the company has very high rolling resistance 22.5 recaps, will there be enough gain by offering them that i pay the difference to have a low rolling resistance 22.5 swapped on. im struggling in the 4.5-5 mpg US range and cant find any info on our heavy'er applications. 60,000lbs empty, 140,000 lbs loaded
Is this a good question?
