Hub-centric or Wheel-centric?

**Kronos1965** · 02-09-2008, 11:58 PM

I appreciate everyone's input as it is helping me make my choice.

NOW as I'm shopping for my tire/wheel combination, I notice that...

1. We have hub-centric wheels.
2. Some wheels that I like are wheel-centric

Has anyone else had this concern?

Our wheels aren't hub-centric, they are lug centric. At least my '04s are, and I'm not aware of any change.

I believe stock wheels are wheel (or lug) centric, meaning they are concetrically positioned with the lugs. My 18x9 Rockstars are hub-centric, meaning they are concentrically positioned by the hub.

it is my understanding, ALL titan wheels are HUBcentric 78.1mm, just slightly over 3". meaning the hub is holding everything center, not the lug nuts.

this is important IMO, can someone verify 100% ?

I believe the factory wheel are hub centric, and because the Titan has a small hub most other trucks can't run our wheels, but we can run theirs as long as we run them lug centric.
Almost all the aftermarket wheels for the Titan are lug centric...

It is an issue I worries about too much after getting LC amd reading we are HC. It has not been an issue at all. Problems I had with front tire wear was balance and tire related. Rims fit perfect as LC.

I've read both answers as being right, authoritatively stated. It isn't like your buying rims with slots in them, I would never use that.

All this stuff is done on highly precise CNC machinery, hard to imagine LC not working just fine in our application. IMO.

Thanks folks for the input.

I can try to find rings if I buy a lug-centric wheel...

Funny stuff...I forgot about those type of wheels...

Titan stock wheels are hub centric(the hole in the center of the wheel holds the wheel center and the lugs hold the wheel on)
the bolt pattern is the old Nissan truck standard 6" on 5.5" had a frontier and those poor bastards have some freakish bolt pattern. don't recall.
I found that the Chevy wheel is the same 6" on 5.5" hub centric and it fits.
for instances pro comp has two part numbers for the 6 on 5.5 one is with a big hole in the center and one is the Chevy hub centric same as Titan. The big hole model you install the center cap from the back through the big hole big cap and the hub centric model you install the wheel then the center cap snaps in the smaller hole. smaller hole smaller cap. looks better and the wheel is held on center buy the hole.imo smaller hole is better

Hub-Centricity
When automobile manufacturers design a vehicle, they utilize hub-centric wheels so that:

* The wheels are positioned very precisely on the car.
* The possibility of shifting while being mounted is minimized.

Lug-Centricity
The alternative to a hub-centric wheel is known as lug-centric.

* The wheels are located solely by the lug nuts rather than the wheel hub.
* As the lug nuts are tightened, they adjust the wheel's position relative to the hub, thus centering the wheel.
* Properly torqued, the lug nuts continue to keep the wheel centered as the vehicle is driven.

Lug-centric wheels require extra care in mounting on a vehicle. When using shouldered nuts instead of tapered nuts, take extra care to properly locate the wheel. Never use air tools to install high performance wheels! Always use a torque wrench and follow accepted tightening procedures.

Wheels in pic are hub centric.

When I discovered I should have bought HC, I called MB Motoring and tried to get rings. They were not in stock and I was told I should not need them, call back if you have a problem.

The reason it is not a problem, is that the Rims have Tapered Seats as do the Nuts that are sold for them. So, in esence, I'm using the LC Technique.

As I claimed earlier, the entire manufacturing process is so acurate that the HC is a non issue when using LC Rims and proper Nuts. Placing a Ring wasn't going to shift where my rims are.

Nobody in their right mind is going to use Flat bottom Nuts on a Taper Seat. Although, I must say, many have made this very serious mistake.

I believe the "FACT" is, we have HC.

I also believe many will claim we have LC, because the LC works fine, with good quality exact sized rims, not them slotted things.

Get rings from your Rim Supplier, or go to Summit or Jegs, call if you don't see the item online or in the catalog. Some items are just too numerous to list, and they prefer to help you select the right thing. New ad on page for www.justforwheels.com for Rings.

Enough said from my little cranium. Bye.

I still don't see where you guys are getting hub-centric from. My wheels are lug-centric. Hub centric wheels use a shouldered lug nut (it's flat on the mounting surface, as it doesn't center the wheel.) The Titan lug nuts are chamfered, since they do the centering.

Remove the studs on the hub and place your wheel on there. The wheels center bore will center itself on the lip or flange of the wheel hub. The Titan has about a 77.8 or 78.1mm hub and the your wheels have a close tolerance fit so that the wheel will center itself on the hub. This is hub centric.

After market wheels have a larger wheel bore and use the lugs and studs to center the wheel. This is lug centric. You could use hub centric rings to center the wheel on the hub.

Sammy Sandbag · 02-10-2008, 05:29 PM

I'm clear on the differences. My point was that my Titan ('04 LE) has OE lug centric wheels. They are chamfered lug nuts with matching mating surface on the wheels. Hub centric wheels have neither of these.

I thought the smaller hole was always better!

I'd say that is the best arguement/response I've seen on this issue. (Which was a new issue to me, 18 months ago). My 06 Steel Rims were also Tapered Seat. The Super Moderator may be right.
