Good morning everyone. I was wondering if I was to change my original 2004 Ford Ranger wheels which are 16 inch dia. to 15 inch dia. would that change my speedometer reading that much ? I would think bigger is slower and smaller is faster meaning more revolutions ? Reason im wondering is because i really like the aluminum slotted wheels (summit racing) and they dont make them in 16 inch . i remember on one of my Chevelles I used to have I changed wheel diameter and I changed the nylon gear that is on the end of the speedometer cable that screwed into the transmission. Just wondering how much from 16 inch dia. to 15 inch dia would throw me off at the speedometer ? Thanks for any help on this.
