22” wheel upgrade issues?

[alexharrel]

Hey guys!

I have a Ram 1500 Bighorn 4x4 with ORP and just had the Mopar 2” lift installed. I’m wanting to upgrade the factory 18” wheels to 22” wheels and wanted to know if it’s simply buy and bolt on, or if I will need anything else. I had seen something about knuckles but nothing conclusive. I apologize for being such a novice in this area, I could not find the results through search.

No issues if going with factory 22 inch wheels.

Just need to adjust the diameters for the speedometer calibration.

What wheels and tire combo are you looking at? The only real issue that would arise is rubbing.

I got 22” wheels with 35x12.5 tires with -18 offset. I’m sure I will need to trim

Hmm, the dealership told me the 5th gen rams automatically adjust the speedometer. Is this not true?

Haha, I think you can get away with a zip-tie on the front bottom of each inner fender liner cover. Unless of course, your truck was made on a Monday. If so, then RIP…

They don’t, but there are several options to calibrate for your new setup.

no. it does not auto adjust. it does not pull from GPS or any other BS. The truck has no idea what diameter tires you have unless programmed. It only know how many rotations the transmission and ABS indicate.

the only thing it will do is when you have a phone connected it will show your GPS speed through a projected app ( carplay or android auto ). That is all 100% segregated from the truck via the security gateway by design.
