Hub Bore Size

[DSOOBY]

Does anyone happen to know the Hub Bore on the 2019? We know the bolt pattern matches the Chevy 6x139.7, but has anyone seen if the hub bore is the same as well at 78.1mm?

Looking to get some hub centric rings for my wheels in advance of their arrival.

I haven't seen any confirmation of the 78.1mm online yet - either via a photo or in Mopar written text.

You have your truck already, right? Why not just take a wheel off and measure it with a caliper yourself?

See Grits, this is why we keep you around here. Good idea. I'll do it this weekend if I catch some free time. Weddings and barbeques are the limiting factor.

Any updates about the hub bore guys?

The hub bire size is 77.8 just like previous model....the 78.1 spacers i bought would not fit on the wheels without a rubber mallet

Are you sure about the hub bore size on the 19 ram is 77.8

That's odd, just installed a set of the yita motor spacers for a Chevy truck and they fit on no problem. No mallet required.

The hub bore is 77.8. I had this confirmed by the dealer and custom offsets when getting hub centric rings for my wheels.

How’s it holding so far ?

Uhhh Ohhhhh...77.8 vs 78.1...not this argument again? See this thread....grab some popcorn by page 3

This thread is interesting...because by my calculations 77.9 is smaller than 78.1, so I am not sure why anyone would need a rubber mallet to pound on a spacer with a 78.1 hub bore size when they claim 77.9 is the right size. I'm thinking they have their numbers backwards.

The spacer will fit fine on to the truck due to the larger size and smaller lip however the rim onto the truck is backwards and putting smaller hole on to bigger lip. Spacer onto truck is 78.1mm hole over a 77.8 lip. Then rim onto spacer is 77.8 hole to 78.1 lip

I just read in a different thread that the factory 22" wheels have a different hub diameter than the factory 20" wheels.

Is that accurate? It seems unlikely that 22" and 20" factory wheels would not be interchangeable.

The truck I ordered will have factory 20" wheels but I've been looking for a set of factory 22's to powder coat gloss black, never thinking there would be any reason they wouldn't bolt right on.

Thanks! Great info.

All wheels diameters have the same bore size, as I suspected.

I use that site exclusively for wheels. I am very very picky about ride quality and things fitting the correct way.
