I just got a set of rota slips in 16x7 and from what I can tell I'll need hubcentric rings for the rims to sit well... Where did you get these? What are the dimensions? Plasitc or metal?

Thanks!

 

no rings - torque in the air with the correct lugnuts and you'll be fine.

 

Call any authorized Rota reseller. I've only seen plastic hubcentric rings...

 

I have conical lightweight lugnuts. Is it really ok to ride with the center of the rim not holding? Doesnt it cause a lot more stress on the lugnuts?

Are the Rota's a Conical/Tapered patterned hole or round/ball like stock Honda?

Only use matched lug nuts, Not ball in conical/tapered hole or vice-versa that's dangerous.

Not unless you over torque them. The hubcentric rings are many times made of nylon, they make it easier to center the wheel when mounting, they aren't holding the wheels on, that's what the lugnuts do.

All the weight will be sitting on the lugnuts rather than some of the weight also on the center of the hub. Isnt that the point of hubcentric rings?

 

There's parts for flat lugnuts and conical ones... Here are the pics of what I'll be using. Is this ok?

Do I simply torque to the same spec as Helms?

yes those are fine. CONICAL =TAPERED

U guys are thinking about oem ACORN LUGS that are round at the seat.

Yep, you're right I mixed them up.

I meant not to use the stock ball lug nuts in place of the conical ones, this is a no-no.

Yes, you're fine.

 

so stock lugs on slips is bad?

Stock Honda lug nuts are ball type and will not seat correctly and or hold securely enough on a conical/tapered wheel like the Rota.



Here's an illustration of the difference.

Yes.

 

Yeah thats good. But just so you know, the lugs are not what holds the wheel on. They just allow the wheel to be pressed hard enough against the hub that friction between the two will prevent movement.

My lug nuts hold my wheels on, can't speak for your car.

isn't that just a roundabout way of saying your lugs hold your wheels on?

You can buy Hubcentric Rings at DiscountTire... That's where I got mine... They even had em in stock...

 

rings are overrated. I never ran them. I beat the living **** outta my car in every imaginable way and they never even came close to falling off

I would get them. Black R is correct, assuming that your lugs are all in line. I hit a bump so hard once with my Rotas that I not only bent the rim, but bent all the lugs too. The rim would NOT center after that until I got the rings.

They work great and are cheap insurance.

If you mean you bent the lug bolts then you should replace the bolts, hubcentric rings aren't gonna solve bent lug bolts.

 

I'll be checking around tomorrow to see if I can get some off a store here (im in europe) then if not ill ride with no rings until i receive them from the US.

Basically what you just said is that the lugs hold the wheel on.

The hub is just the flat surface on the other side of the rim, holding the lugs in place.... I suppose you could say the hub pushes back at the same rate as the lugnuts are pushing in the opposite direction But when a lugnut comes loose.....

Ever lost a lugnut while driving? or had one or more come loose? No question what holds the wheel on after you've been through that.

I'm gonna take a shot at explaining what tommymoose was trying to say....

The lug nuts should normally only have a TENSION force on them, not a SHEAR force. The tension force obviously holds the wheels onto the hub.

With that tension force, the friction between the hub and wheel absorb the shear force of the weight of the car.

I'm not sure that he's right, but I'm going to guess that he is in most circumstances. If you torque a lug nut to ~80 ft-lbs, the tension force it applies is probably close to 800 lbs, maybe more. Times five lugs, that's 4000 lbs. If the static coefficient of friction between the hub and wheel surfaces is 0.5, that means the friction between the hub and wheel will hold 2000 lbs of force before they slide and cause the lugs to have to withstand shearing force.

I pulled every one of those numbers out of my ***, but I'm guessing I'm close enough to show his point. The lugs hold the wheel on the car, the friction between the hub and wheel hold the car in the air. If the hub/wheel were smooth and lubricated, the wheel would wobble and the lugnuts would shear.

Back on topic:

Screw the hubcentric rings.

p.s. I run tapered lugnuts on OEM wheels (runs and hides in a flamesuit)
