hub centric or lug centric

[cary]

this may be a dumb question, but i know 4runners have hub centric wheels, but i am wanting to get a new set of wheels in the near future, but the ones i am looking at are procomp 7031. i noticed that they are lug centric.
will they still work?
please explain
thanks

In terms of factory wheels lug centric sit on the lugs while hub centric the center bore is big enough and the wheels sit on the lip on the hub. They both work but it's always better to get hub centric. The ride will be a lot better, less bump steer, and less stress on the lugs causing failure. In aftermarket wheels, some will either be too big of a bore, or too small because they fit a variety of vehicles. You can always buy hub centric rings for wheels with a bigger bore. This will rid the issue of being lug centric giving you, in a sense, both lug and hub centric. Unless you're buying aftermarket wheels designed to be toyota specific, most likely they will be lug centric.

Lug centric aftermarket wheels like the Pro comps pertains to the center bore/hole size which is 108mm in diameter- this is what you want for the 4runner as the wheels center hole is big enough to fit on the trucks hub.

Hub centric aftermarkets have a center bore size of 100mm which will only work on Chevy's, nissan's etc.....

Confirm this with the seller, though.

If you do go with lug centric make sure you install new lugs that are built to hold the load.

My procomps are lug centric

the same as the OE 5 spokes that came on my 00'. Lug centric wheels are balanced using the 6 lug holes as the center of the wheel while hub centric uses the hub hole to center the wheel. If you buy a hub centric wheel youll need lug centric spacers in order to balance it. If you buy lug centric wheels your fine.

Are all hub centric after markets a 100mm bore? are all the "lug centric" aftermarkets designed to actually sit on the lip on our hubs?

My understanding is that all the 4runner OEM wheels are hub centric, not lug centric.

I always heard that the 3rd Gen 4Runner Stock wheels are lug centric. That's the whole reason for the Haweka adapter, to center the wheels on the machine. If they were hub centric you wouldn't need it. You don't need to use the Haweka on most after market wheels since they are centered at the hub.

4Runners in general have a very sensitive front end, and it anything is off just the slightest bit, you will feel it. Not every lug centric wheel needs the Haweka, but you will on the 4Runner if you want the best balance with your stock wheels.



***In the early 2000's the first upgrade most of us did was to get rid of the stock Toyota wheels because of the balance issues. This was one of my first upgrades - got rid of the stock Duncrap tires and stock wheels. The only place back in 2002-2003 that had the Haweka adaptors were the Toyota dealerships and I did not want to pay their price to get my tires rotated and balanced.
Back then you had trouble giving away your old stock Toyota wheels when you upgraded to after market wheels.

Toyota published a TSB that requires the use of the flange plate adapter when balancing wheel on ALL TOYOTA VEHICLES.


Good info on this Thread:

hub centric or Lug centric - YotaTech Forums

Somewhere on YT there is a monster thread that shreds this issue to death. There is a baby monster one on here that does the same thing. I'm sorry I don't have the links in my collection. The conclusion I reached reading both was that the stock wheels are BOTH hubcentric and lug centric. The reason for the use of the Haweka adapter is that the profile of the centering cone on the Haweka adapter is such that it contacts the inside of the wheel in such a way that the wheel cannot be fixed in place securely, preventing an accurate balance.

The fact that the lugcentric adapter is used and works is because the wheel is ALSO lugcentric, and no mounting issue comes into play when it is used.

As I know nothing about aftermarket wheels, I won't comment on that issue.

 

[ALBPM]

Yeah, YotaTech seems to be down right now. But as I recall most of the alloy wheels from the 96-02 period where lug centric and the steel wheels where hub centric.

Gadget and JA - jalaber went after Toyota over this issue because most of the dealers didn't even have the Haweka adapters in 2002 - 2003 and could not balance the alloy wheels properly.

YT is back up....

*** Now, this is why back in 2003 after I bought a set on Hub Centric aftermarket wheels I ended up basically giving a guy on Yotatech my 5 spoke Alloy wheels for the mere cost of the shipping charge.
I had to get rid of the damn stock wheels as they would not balance worth a crap unless this one Dealer in town balanced them.

I took a break and didn't keep up with YotaTech or Toyota stuff for about 4 years. Then when I'm ready for more upgrades - "new suspension" I started searching Yotatech and then found T4R back in May-June this year.

I was quite surprised at the number of members suddenly wanting to put the old Stock Toyota Alloy wheels on their Runners.
I thought WTF!!! are they doing this for...you are lucky if you can get them balanced correctly.

As an "Old School" Original owner of my 02 Runner I wouldn't go near a stock wheel for the 3rd gen Runners. Just my Old A$$ Opinion....LOL!!!

--------------------------------------------------------------------------------------------
Found this from "waskillywabbit" while seaching YT for lug vs. Hub Centric stuff.....

285s on a non-lifted 3rd gen will rub like a fat woman in corduroy pants running a race to get a big slice of cheesecake.

And then wait until you try to TURN...

Are all hub centric after markets a 100mm bore? are all the "lug centric" aftermarkets designed to actually sit on the lip on our hubs?

My understanding is that all the 4runner OEM wheels are hub centric, not lug centric.

That is the reason why I implied to the OP to confirm it with the seller before actually buying.

My brother of course without seekin' advise ordered a set of Procomp wheels for his 99, and ordered the Hub-centric type( are 4runner's hub-centric? he must've thought so!. Anyway the tires were mounted and all, only when we fitted the wheels on the truck it wouldn't because of the smaller bore size. It wasn't a good day!

I have had 2 sets of aftermarket wheels and the only spec I go by for fit is: 6-139.7mm / 6-5.5" plus model, make and year.
Both sets have been hub centric so I don't have to deal with finding a shop with the adapter to balance them.

Make Model Year.................Bolt Pattern.........OEM Wheel Size... Stud Size ....Hub Center.. Bore Offset

TOYOTA 4-RUNNER 1986-02..6 X 139.7 6 X 5.5...........................12 X 1.5.............106.0

In my research I read that my 98 was lug centric, thus the reason I can never get it smooth on the highway. I had a shop in town here balance them on the road force balancing machine, and that didnt really do anything. A few months later I brought them to Toyota and paid $110 for a balance with the same machine using the haweka adapter. It helped some, but didnt get it smooth.

So what determines if it is hub or lug centric? Is it the hub itself? Or the wheel? Or both?

The wheel determines if it is lug or hub centric.

For those with aftermarket wheels, are we able to get hub centric rings for these trucks? I've searched and haven't come up with much.

Here you go. Ebay hub centric rings

Thanks for the link! Are the sized accurate though, our hub diameter is 108mm? I'll be measuring my wheels to make sure before ordering anything, I can't see them all being the same. That's a mighty thin ring!

 

[jrm]

My experience so far

with my 98 SR5 and 00 Limited is that every time they didnt use the lug attachment to balance the tires-wheels they never came out balanced. And every time they did use the lug attachment the tire balance came out perfect. YMMV.

What i cant believe is how many shops have no idea about lug centric balancing.

The table I found said 106mm but best to measure.
