Have i lost my mind.. dropping tire size...
I have a 2002 ranger 4X2 with a 2.3. K&N cold air intake and flow master exhaust.. I'm running 31X10.5 general grabber at2 I love the tire but i hardly see 5th gear and have no power at all. Oh i have the 3.73 rear. I have a extra pair of rims and father in law donated 4 205/65/15's which is 25.5in dia. going to see what i get for power and mileage.. truck is rated for a 225/75/15 tire which is 28.3 in dia. with the 31's i'm getting 27mpg avg i drive 90 miles a day round trip to and from work.. who has a guess on what new mileage will be... hope to try out this weekend... I think i may end up buying new general at2 tires at recommend size so i can pull my boat and save the 31's for when i get my father in laws 4X4 ranger with v-6....
