I have a 2014 Ram 2500HD 4x4 w/ 5.7
Looking to make sure about a few things regarding wheels. I believe the Bolt pattern is 8x6.5 or 8x165.1. Ive heard the hub bore is 77.7 as well as 120... I cant figure out which it is. Want to make sure when I purchase wheels the hib bore is as close as possible. Last is my concern about the studs thread pitch. Is it 9/16 or 14x1.5mm Im pretty sure those two measurements are super close to being the same thing but just want to make sure as to the Specs as specific as I can get. Thanks for any help

Come on 33 views and no one can add any info. Just trying to verify before I purchase a set of wheels. Trying to get exact info rather than going off what I heard. Im 99% sure its a 8x6.5 or 8x165.1 bolt pattern. But I have gotten contradictions to the lug thread pitch of 9/16 and 14x1.5mm, also Ive seen 2 different dimensions for the hub bore. Can someone please help. Thanks

Yeah Im pretty sure the bolt pattern is 8x6.5 which is the same as the 8x165 s Im good with that. Thanks


I believe that the studs are metric. I am sure I read somewhere that they changed over during the 4th gen. The best way to find out is to get a caliper and do the measurements on your truck and then there will be no confusion.
Yeah I guess thats where Im at, just thought with the 1000s of Ram owners on here someone would have been able to verify the dimensions without me having to do this. Not really looking to jack the truck and pull the wheel just to get the measurements but it looks like my last option. Thanks for the reply
