mpg
 

hey guy i was wondering what would be best tire for mpg on my 97 F-250 with 3.55 gears? any help would be nice Thnx.

Stock... Your already turning slow... At most a 33" or 285...

would the 265 be good

Would be fine.

would it be dumb to goto 4.10 gearing for mpg

that would be the opposite way you would want to go to gain mileage. 3.55s will get you the best mileage.

i got 3.55s with 265s, my best is 22.5 mpg, i did 21.3 with the a/c on, that was doin 65-70 mpg avg speed

Hey cbps;
I have written a thread how to find out best mpg.
Just have a look:
