would stock rims from a 4x100 honda civc be hubcentric on a cobalt? If i'm not mistaken their hub diameter are basically identical...

 

If the hole fits the hub then yes, it would be ok. If not you'll need a hub adapter.

 

I believe that all Honda wheels are lug centric, so as long as it fits you'll be okay. A hub adapter is a good idea to keep the clearnace right, but on civics and on our cars the lugs are what positions the wheel, not the hub. Hub centric wheels will have lug holes with no taper to them, and use a lug nut that has a big flat washer on it.

 

The lugs haveing a taper isn't what makes it lugcentric. Our wheels are hubcentric.

the difference between hubcentric and lugcentric is where the wheel is balanced from. your typical tire shop uses hubcentric balancers with the big spindle and nut capturing the wheel to be balanced. while most race shops use a lugcentric machine that attatches the wheels to a hub with wheel studs and lugnuts to be balanced ensuring the wheels are balanced for the condition they will be used. hubcentric balancing is fine for commuter cars never or should i say rarely reaching speeds over 100mph, but for high speed running lug centric is more accurate.

 

Umm, no. How they are balanced has nothing to do with it. Just because my wheel is balanced with a hub spindle doesn't make it a hubcentric wheel. It is how it fits on the hub of the car. Hubcentric fits the center of the hub tightly to center it and the lugs are there only to hold the wheel on.. Lugcentric uses the lugs to center the wheel and hold it on.

 

ok so based on that other thread i get this quote " Other Cobalts have a 4-100 pattern, which is a typical Honda pattern, and widely available. The hub diameter is 57.1mm."

meaning hubcentric rims on a civic (the stock rims) would be hubcentric on a cobalt...

<edit> my understanding of hubcentric is what cawpin said, therefore why I'm asking... I assume if the rims were NOT hubcentric I'd need wheel spacers or something

 

If 57.1 is our hub diameter, and the wheels have that hub diameter, they will fit. If they have a larger hub diameter you will need a hubcentric adapter.

 

how do u tell the diameter of the hub and if you need an adapter or not. What will happen if you dont use an adapter when you should? I just got new rims and tires and they seem a little funky. The steering wheel fibrates around 55 but then goes away around 60 but it doesnt do it all the time. Also when braking the pedal vibrates around 30. I'm not sure if this is due to a balancing issue or this hubcentric thing. Any ideas? By the way i have BSA 333 rims with 215/40/17's

 

I had to have a Hubcentric ring for my balt

 

I hate to tell you, but the taper does mean they're lug centric. Nearly every single wheel out there is lug centric.

Think about it...each lug hole in the wheel has taper to it that matches the taper on the lug nut (or lug bolt if it's a BMW or VW or something). If you try and get the wheel perfectly centrered using the hub, then the wheel will just fight itself because of the taper on the lug holes trying to center it based on them.

The only way for a hub-centric wheel to work is not have any taper in the lug hole, like most toyotas use.

A taper in the hole will cause the wheel to be guided into position by the nut.

I've been a auto tech for a long time now, and our shop has a machine that can balence using either method, so I'm familiar with the differences and how to spot them.


All that said, it's still always a good idea to have the right size hub spacer installed. If nothing else, it makes them a hell of a lot easier to take on and off.
