2003 3.0L 2WD
the picture above is with 17" rims. the tires DO run, they are 4" tallser and wider they stock.

I would like to get new wheels and tires. My thing is do i get 15's or 16's. i do have bigger tires and wheels on the truck now that came with the truck used. with that being said my mileage is not correct (average about 214-250 a tank)

I loved the wheels i have on the other Ranger i had witch were 16's

now the questions is I want to get better milage, what should i do?

 

better gas mileage? that would probably be 15" on 235 75 15. although the appearance takes a hit
or if you have the rims above get a smaller profile tire closer to stock

 

For better gas mileage, open the drivers door and check out the sticker on the door jam. If you put the factory tire size back on there, you'll be going back to stock numbers for MPG, assuming there are no other performance modifications.

 

i do have Flowmaster 40 series , that is about all as far as performance. everything else is stock.
