new tires and revs per mile
alrighty, i recently got a set of 265 75 16 destination mt's and my old tires were the same size, but i'm noticing that before i would go one mile in sixty seconds exactly at 60mph and with the same size mudders i'm going one mile in 1 minute 3 seconds and noticing a drop in fuel economy of 3 mpg 17mpg to 14mpg. perhaps the tread is taller giving me an off reading on the odometer? i looked around the web for revs per mile and i'm getting 637.23 for this size. take it that it has increased a bit with these tires and not sure how much i would increase it by on my tuner. kinda stumped, any input would be cool.
