had 195/75/14 on my 97 reg cab ranger, went to 235/70/15 and the gas mileage went noticeable down the tubs? wasnt expecting such a big drop off! :(

 

Bigger tires = shitty gas milage that's just how it goes. The only way around that is to re gear.

 

Funny thing with tires is I went from the stock edge wheels. I got another set of 15's and slapped on 31x10.5's and oddly enough the gas mileage stayed the same which is only 19 on a good day. Same when I put the 245-75-16 on my truck as my winter wheels. I do commute in Pittsburgh everyday but its never changed from 19 mpg through any set of tires. Oh yeah and I do drive like an a**hole hence horrible gas mileage in the 3.0

 

rangers arent known for great gas mileage

 

Well the old girl was getting about 24-25 MPG with the smaller tires. I just put a new air filter in it and the one rear tire was very low on air.. I'll see what shes at next time i fill up...
