Rims 17 to 20's ?
 

I'm currently rolling on BFG AT KO's 285/70/17 and looking at maybe picking these up http://grandrapids.craigslist.org/pts/1316427785.html

Can anyone tell me what affects this might have on the driveability/performance?

Both being 285's, it's mostly rim diameter difference...just curious if that affects much or not and what the diff might be, positive or negatives?

Thanks!

If you are planning on those particular wheels, they will not fit your truck. Those are 5x5.5" wheels. You need 5x135mm, which is not the same. The 5x5.5" is only on F150s up to 97.

with a smaller size sidewall you will feel more bumps in the road and have a harsher ride.

I called the guy and mentioned your comment. He suggested the rims accomodate 5.5 thru 137.9.
What do you think about that?

Thanks!

My comment is B.S. 5.5" is only prior to 97. 97-03 and the 04 heritage are 5x135mm, and 04 up are 6x135mm. The 5.5" and 135mm are NOT interchangeable.

OK, passed on deal. Appreciate the help.
