How important is hub-centric? Hub bore is 106.1? Tolerance?

most methods are 108

 

Method emailed me and said their wheels are 106.25 and come with rings to fit the 106.1 of the Toyota. Can that be right? A ring that fills a .15mm gap? That would be a ring with a thickness of .075mm? That's paper thin.

 

I think they typo’d that response. I’d ask for clarification.

 

if the ring is made out of aluminum it would be fine, but I am not sure I have ever seen a hub ring that thin? I too would ask for clarification. Before I bought my 4 Runner Pro wheels I inquired about a set of KMC XD Wheels and they told me the hub bore was 106.25 and that they would be "fine". obviously I passed on them. 106.1 is hub centric, any deviance from that and well, it isn't. plain and simple.

 

I recently put on wheels with a 112.1mm bore size on the Tacoma. I asked the tire-shop if I'd need rings, and they said they'd let me know.

After installation, they said everything went smooth and the "wheels took without needing rings". I'm assuming if they passed up a chance to sell me rings, then they're telling the truth. I don't know if this helps or not.

 

this "can" be true in some cases. perhaps the shop you used got very lucky? perhaps the wheels you chose took a shank style lug like the factory? but with a standard acorn style lug I would have insisted on the rings. here's why: say the shop who installed the wheels/tires got lucky and you have no vibrations whatsoever. take your truck in for service to get your tires rotated and well, they don't get as lucky as shop #1. then you are going to have vibrations.

some people will swear they never use hub rings, but I personally will not install any wheels that aren't hub centric without them.

 

Plastic hubcentric rings cost what.. 20-30 dollars. For the peace of mind knowing that your wheel is centered, I think it's worth it. But when I used them on my Subaru, the rings got stuck onto the hub. I could never get them off...

 

Thanks for the info. I've been purchasing tires at this tireshop for almost a decade now, so most of my work will be done there in the future. I'll ask about hub rings again when I go in there for my first rotation

 

Any update on this? I’m looking at wheels with the same hub bore for my Taco.

 

What hub centric ring and lugs would you run with a wheel that has a 112.1 hub bore for the Tacoma’s 106.1 hub bore?

 

There is not a single car on the planet where the weight of the vehicle is supported by the tiny flange on the wheel hub. The lug studs also do not bear the weight of the car.

The clamping force of the lugnuts affixes the wheel to the hub face, joining them. The hub face, not the tiny centering flange, supports the weight of the car.

All modern vehicles are lug-centric, so you don’t have to stress about the center bore on the wheel so long as it’s as large or larger than the hub center flange. Having the center bore and flange diameter match makes installing the wheel a little easier, that’s all. There are some older, specialized vehicles with hub-centric wheels. The only one that comes to mind is the Pinzgauer, but I would love to hear of some other examples.

 

I am running Method Vex 311's. bore is as you said 106.25 to the 106.1 of the OEM, I feel not shake/shimmey.

 

Uh, I think you have things reversed. All modern vehicles are hub centric with very few exceptions. The last ones I remember were a 70s era beetle -

 

Most BMWs and other vehicles that take wheel bolts (instead of studs) are always hub centric because getting the wheel on the car would be pretty hard without that... trying to balance the wheel so that everything lines up while also threading the bolt in there would be a chore.

 

I've recently purchased some wheels requiring 106.1-112.1 hub centric rings. Only after purchasing did I really get into the weeds on learning about all of this stuff. Seems to me that hub rings primarily serve to assist with proper centering on installation (especially when tightening the lug nuts). I think BearWithMe was pretty spot on about how the load is supported.

My further research was also very enlightening, if you wish to read up on the topic, these links below had some good information. If anyone has more information on the mechanics/physics or where to find top quality hub rings in the size above, I'm all ears. Cheers.

Hey man this is super late lol, but do you have the tpms and lugs you use? I was looking at getting these
