Adjusting truck to new size wheels???

dubz1 · #1 (**permalink**) 05-24-08, 06:25 PM

I have new 26" wheels. The diameter of the new tires are slightly larger than the OE 22" tires. Will the Predator programmer fix the speedometer to read the correct mph?? If so, what are the steps I need to take? Thanks!!

What size are your tires?

That would probably work, the Preditor will work too, and you can get more performance out of your truck.

It has a tire diameter adjustment feature. As I recall, maybe somewhere near the speed limiter adjustments. You need to get into the "adjust paramaters"/ "customize tune" feature. I can't recall precisly without having it in front of me, sorry.

You have to go to the custom tune section in the predator. Go to www.diablosport.com and download the instructions it tells you there. All you do is go the the adjust tire size option sub menu under custom tune menu and enter the new tire size.
