Calculated tire CPM?

[Lonestar10]

Michellin/BFG are the only thing i run as i have a michellin national account and get a good price savings right now Mich Xline Steers and BFG DR454 Drivers with Mich XTEs on the trailer.


Xlines - about 70k miles are like new 6mo old
DR454s - Ied say 7/8 3/4 of original tread at around 10mo old 100k miles.
XTEs - Put on over christmas break - 30kish miles look like new still no abnormal wear.

ied say my average driving speed is 67 with spread axle 48' flat.

everything might last a bit longer now fuels getting up there rates have increased but not as much as fuel so ima start dropping my speed to offset the fuel costs.

i can almost bet you my fuel mileage on fairweather days and speed i drive
67-70 - 6.3-6.5mpg
63-65 - 6.5-6.8
60-62 - 7.0-7.5

need to save that money this year Tax man had to fully deduct my T680 i bought as i didnt spend enough money and uncle sam wants his cut. which means this year i wont have anything to depreciate besides the trailer once i get rid of the Lonestar unless once i hand my taxes over the to bank they say i can build my dream shop/shouse this summer.
