    Hi. I am new to the forum. I have a 2009 Ford Ranger XL with a 2.3L. The stock tire size is P225/70R15. I would like to install the same size of tires the V6 Rangers come with P235/75R15. My concern is if these tires are to big and heavy for the 4 cyl engine. Will if affect my fuel economy? How do I calibrate the speedometer for the taller tire, can I change the speedometer cable gear and if so what gear do I replace it with? Thanks for the help.

    I had an old toyota pickup in Alaska and it had 14" tires on it and I had an old Ford van that had nearly new studded snow tires on it when it crapped out and I accidently found out the wheels would fit on the toy truck (flat tire no spare 26 miles to the fixin place). I put both of the 15" wheels on the back mpg went from 15 to 20 mpg I was tickled. As far as the speedo goes just guess your speed higher than indicated at first and the first chance you get when your on an interstate note the beginning milemarker and odometer reading and drive 50 or a hundred miles and compare the actual miles to the odometer and you got the difference.:D

    However my 2.3 is a gutless wonder and larger diameter tires on the rear will lower the rpm of the engine at any given speed sooooo it might be a problem if you ever have to pull a trailer up a steep hill other wise if it wont hold od you just have to shift down conversely it will increase top speed on a long downhill. Truckdrivers call that longer legs.
