Does anyone know what the center bore is on our hubs? I now understand why Ruger got a custom drill for his Clones, he thought it was the bolt pattern, but it's the center bore. center bore on the 20x9 wheel is 72-78 and I know a 111 bore will fit. so it's somewhere between there!

I'm so glad the crappy place I ordered from to begin with was out of stock...

 

I just found this if anyone can confirm, I will be looking for a second reference

it says 77.8 center bore for 05 and up.

edit, i found this one too, agrees with the previous one.

The wheel I want is 78.1 and the hub is 77.8... why wouldn't that fit? is it the center ring thing they need room for? I guess you want the wheel riding on the hub and not the lugs right? less than a millimeter doesn't leave any room for a center ring i guess..

 

Yeah, the center bore size is 77.8mm.

I'm glad that you started this discussion, I was just thinking about the 'shake' and 'wobble' problems some guys complain about. This could be the solution for those issues.

When you're running aftermarket wheels with a larger center bore size than 77.8mm, you should also install hub centering rings so the wheel is centered correctly. That is assuming our wheels are hubcentric, and not lugcentric, which would not require the hub centering rings. The rings are simply aluminum or plastic rings that are attached to the wheels.

agreed, even if they are lugcentric, I like the idea of my wheels having that solid contact with something else. Too many variables in any case, and rings will elimitate some of them.

So I scratched the Clones, KMC doesn't really have a part number for our bolt pattern. They sent the wrong data sheet to every distro, at least that's the theory of the guy from custom wheel express that I talked to today. They have a part number for a blank wheel but it hasn't been in stock for ages. So even a custom drill would be hard to get. This makes me slightly sad, but happy at the same time. It gave me the chance to look for more wheels, and I found these

Decent looking sport truck wheel, I'm not a huge fan of those wheels that look "import tuner" like. and rockstars/monsters just dont say sport truck to me.

It looks like any aftermarket wheels will definitely need the hub centering rings. Usually when you order the wheels, they would be included, at least from a reputable company.
You'll know if you need them when you're cruising and get that shake, usually at about 55 mph of higher.

Just curious if those of you with have aftermarket wheels have the rings installed?
And those of you who don't, and have that shake, get them.

 

after about a half days research I figure my ideal set up for wheels (will be purchasing in next week or so) on my stock ride height 2005 dakota st will be a 17x8 (possibly 8.5) by 5x5.5 or 5x139.7 lug, maybe a (-)offset of 19mm and am keeping in mind stock center bore is what I can tell 77.8mm <----still true??

As I find more constraints I need to follow I find places like amazon have less and less to actually offer and am looking for a site than can offer searching for tires by all these restrictions.

here are a few questions related to buying rims that i think would help me out alot. I am a fan for function over looks so want these things to fit nice and ride nice. also looking to spend under $200 per wheel and aluminum over steel for sure. American Racing looks like the ultimate way to go but are definitely lacking pop.

below are a few questions that would definitely help me with my search.

Q1: is the dakota hub or lug centric and if lug, will a larger center be np?

Q2: will getting a bigger bore and using hub spacers to allow fitment make the ride funny? ..if in fact it is hub centric..

Q3: what would you put as a min and max size tire on a 17x8 rim?

Much appreciated.

 

A1 - These are hub-centric.
A2 - Adding spacers may push the moment arm too far out to be handled by the front end. (think holding a weight in your had with your arm extended vs holding it up against your body)
A3 - see any of the tire websites for rim width vs tire size compatibility.

 

A negative offset of 19 will push the wheel way out, wheel bearings and other front end parts will not be happy, and the tire may rub on the front bumper fascia. Read the official tire size thread up top for tire sizes that will fit properly.

 

Most wheels these days are lug centric. As long as the center bore is larger than the lip on the hub than the tapered lug nuts are what keeps the wheel centered. Hence the star pattern during the torque phase.

You can run either type of wheel but if you run hub centric. The wheel center bore needs to be as close as possible to the size of the hub ring. I hate hub centric because sometimes it makes the lugs not line up so nice. Good aftermarket wheels will have a huge center bore and as long as you shop for 5x5.5 or whatever we use, and use tapered lug nuts. You'll be fine.
