99 2500 HD SLT 5.9L Diesel long bed.

Empty - 16-17 City and 23-24 highway

27ft Travel Trailer - 12-13 city and 15-16 highway

 

My speedo is off by about ten miles per hour cause of my 35's, could it being off like that screw up my gas mileage?

 

i'm getting between 5 and 7 mpg with my truck. best 9 mpg on the interstate in south carolina and not letting the auto tranny shift out of overdrive most of the way. think about that if your planning a lift such as mine.

gettin between 19 and 20 but im drivin mostly highway everyday for work
just put on a k&n intake so we'll see if that pushes me over the 20 mpg mark

 

I get about 12 mpg highway in the 95 Ram 2500 with the 5.9L and a 5 speed. Don't know what I get in town, don't want to know.
