[QUOTE="akf250, post: 1502738, member: 2655"] Would you be pushing the gear ratio envelope to far by running 3.31's and 22 inch rims with maybe 305 wheels? I'm looking to get MAX fuel economy out of a F250 with a truck bed camper in the back. What is the highest gear ratio combo you would want to run with a 22 inch rim and tire before your RPMs would be so low it would surge? I'm about to put True Tracs front and back and want to play with ratios lower than 3.73 I'm thinking 3.31 or 3.55 with 22 inch rims [/QUOTE]
