Hi guys, i'm going to buy some second hand wheels for my XC.But i've been told to be careful as the hub sizes are different.For example XB wheels will not fit XC.The bolt pattern is the same but the hub sizes are different? XY could be different again. Anyway of telling if a wheel will fit without actually bolting it on.Is it possible to measure the hub size? What is the diameter of the hub? Any advice apprecated .

have a good look at your xc hubs you will see there is difference between xc and early smaller hubs. the xb hub (the round bit in the center)is visably smaller. measure your xc hubs before you buy new rims

Hi Glen
Another thing to be aware of if you're not already is even if a rim bolts up it needs to be a snug fit where the hub comes through the rim. The wheel studs are only meant to locate and secure the wheel. The hub should be the load bearing compon

So true as if you hit a pot hole you can break the studs and loose a wheel due to the hub not load bearing.
I informed a disc brake dealer of this and surprisingly he wasn't aware of it.
I'd just always buy large hubbed wheels anyway.

The notable exepton here is XW-XY Falcons & MK1 Capri's don't have a load bearing wheel hub on the rear. The studs do all the work.

The 1/2" Ford studs are up to the task if the wkeel does not match the hub - some other brand cars have 3/8" or so studs that snap easy...

I have often wondered whether the hub is supposed to be load bearing or not. It sounds logical but there are so many cars that are not designed that way. Fords from the mid to late 1930s are one example. So are VWs and FJ Holdens. Some Falcons and Cap

As a mechanical engineer, I'd like to put in my 2 cents. (Not to say that I'm correct, just my opinion!)
I had the same argument with my brother.
For the rim to be the load bearer, the rim would have to be an interference fit. Which would mean that it

HQ - WB wheels on a Commode (or vice versa) IS a recipe for disaster. HQ - WB's have a PCD of 5/120.65mm whereas Commodes have 5/120mm. Not a lot of difference, but enough to put enough side loading on the studs to bend (and eventually break) them.

Actually Dave, you're 100% correct.
I am ashamed. :)
I stuffed that one up entirely.
Mind you, we have been doing exactly (XAGTLY!!!) that for years and haven't had a problem YET!
Bugger it, it's not worth risking hey!
I still stand by the fact th

My HQ has early Hurricane mags that only use the studs for support. I have read that this style of mag is now illegal in some States as the centre does not carry the weight of the car....I hope that's not the case in WA...
There are MANY horror stories

correct me if im wrong.. but isnt it the wheel nuts tat turn the wheels? n if they can withstand that force required to turn and slow down a wheel on the road.. then they should be able to hold some of the cars weight without snapping off..?
just a ran

Force, be it shearing or driving, is transferred via rotor to wheel rim through the studs by correctly tightened nuts. That is, when the rim is located against the rotor, the clamping force of the nuts to the studs bears all of the loading.
Yes, a clo

So what's the difference between "shear" and "driving"?
When accellerating or braking, thestuds are under shear forces.
Personally, I believe that the studs do all the work.
I'm using late model disks etc on my coupe with the original globe mags.

I have an old "Sports Sedan" which was built in 1970 , there is a tremendous load on the wheels of this car as the "off-set" is huge ( 10" x 13" rims = 3" in , 7" out") the front's don't fit tight on the hub and neither do the rears , so the full load is

it is still the wheel studds that transfer the rotational energy from the axle into the wheel and thusly tunring the wheel. likewise the studds would have an enormous amount of torque put on them when starting the car moving
