correct wheel centre bore?
I have just aquired some 13x7 inch steel wheels.
The pcd is 100 which is the right fitment but centre bore on the wheel is slighty to big and there is no support from it. So the wheels are hanging off the bolts only.
Is this common on other non vw wheels or should the centre bore be a tight fit on all wheels fitted.
Don't want to fit the wheels if there are not going to be safe or cause damage!
Heard something about adaptor rings but don't know what they do!
Any advice would be really good!
Cheers

Centre bore should be 57mm. Do the wheels you have have a 'cut out' in the centre on the reverse side ? Most aftermarket wheels use plastic spigot rings that locate the wheel onto the hub. These push into the cut out. If not then you can still get spigot rings that will do the job - you'll just have to measure the inside diameter of the centre bore on your wheels and get rings that take this down to 57mm

The centre bore on the wheels are 65mm. The bore has just been press out with nothing on the reverse. The wheels are basically the same as a standard 13inch steel wheel (mk1 golf) but with a 65mm bore.
Would the spigot rings fit on to this type of wheel? Do you now where I can hold of these. Don't no anything about these so any more info would be really good.
thanks again

The center spiggot as far as I'm aware is to help getting the wheel lined up to get the bolts in. Olders car wich have wheel studs and you use nuts to secure the wheel dont have this feature.
Trying to hold up a heavy wheel and get a bolt through is diffcult, but once you have all 4 bolts tightened up the wheel will be central and they are all that supports your car.

are the bolts alone enough to support the wheel?. It looks as though on the standard vw wheel the bore is a tight fit into the wheel which acts as extra support.
I'm just worried I'm going to do some damage and that the bolts will not be enough to support the wheel propably!

The bolts will hold the wheel on fine as long as they are tight. The centre is for location and ease of puting bolts in. make sure you do the bolts up across the diaganol and your wheel won't go anywhere.
Four bolts have to fail before the wheel comes off!!!! don't put any grease or oil on the bolts either as this can cause then to come undone. A friend did this may years ago and his wheel did come off!!! partly his fault due to not stopping when hearing a clunking from the car to check things out.

But if you still are unsure pop into a tyre fitters and ask them their advise to double check

cheers for the help guys!
Do the spigot rings act as a support or are they just there to help get the wheel on in the right place???

I remember a similar question on the Caddy forum. I mentioned that while preferable to have them, the spigot rings weren't 100% essential. I myself have run a set of aftermarket alloys without them on a previous car. The guy who runs the Caddy forum (who's also a mechanic and has built a VR6 Caddy & therefore 'knows his stuff'), insisted that the spigot rings were essential in spreading the load and that you were in for all sorts of problems if you didn't have them.
I can only go on my previous experience. TBH, I'd do a Google and see if you can find some.
Upto you !

Only Plastic!?
They could take a lot of loading as they are acting in compression.
Plastic spacers are frequently used in the building industry to level concrete castings weighing many tonnes.
I would not hang a wheel off bolts only.

Hi guys, just a note when i had my astra on 17inch wheels. I had no spigot rings and fitted them without .The bolts alone will align the wheel enough so i thought. I couldnt understand why my balancing was way out when the week before i had new tyres fitted n balancing. I took the car back to the garage and it was explained to me that the spigot rings act as perfect aligning of the wheel to the face. So from that i now know the bolts dont actually align the wheel perfectly. Sounds stupid but is true, i was caught out there. I had to buy a full set of new plastic spigot rings, and YES it cured my steerin wheel wobble. Hope the info was a help.

The spigot ring is important.
When I bought my westfield it had the rears spaced out so they filled the arches but made the handling crap :dontknow: and the spacers rendered the spigot ring useless. When I went to turn down the bolts after removing the spacers I found that all 8 had bent to some degree.

When you use spacers on a car the bolts are extra long and are prone to bending, that why spacers are not recommended.
On the centre bore bit this is what I found on 'tinternet'
So I would conclude it a balance thing and this is the solution, this problem would compounded by bigger and heaver alloys I presume.
Learn something every day, I'm sure if you know the make of alloy ,you can get a set of spigots from them.

The centre bore is the hole machined in the centre of the alloy wheel. It is essential the alloy wheels purchased have the correct centre bore for the car they are intended otherwise you may experience balancing problems.
Often alloy wheels are supplied with spigot rings fitted in the back of the wheel to get the correct fitment.

thanks for all the info.
spoke to the company who prduced the wheels and they say that it's ok that the wheel doesn't fit on to the bore, and that the bolts are enough to support the wheel
not a 100% myself but will get some spigot rings and try it out.
