Im A Size 12, Really!

[vmail]

hi, I know nothing about wheels (alloys) to me if a car has 4 studs then any 4 stud alloy should fit, I know it wrong so could someone teach me the basics.

if I know the name of the wheels then where can I get the size info from

and viceversa if I know which car etc

does the engine size matter, ie will a 1.0L and 1.3L of the same make car can have the same wheels?

cheers

need info for Cilo and the 17" Black Widow

engine size doesnt matter as the rolling radius ( the amount the wheel turns) should be the same if you get it right, ie choose the right tyre to go on it...

offset, pcd if you dont get right you've waisted your money and tbh the shop should be able to tell you anyway...

when you put the 4 bolts back in make sure they are put in the right way ie dont bolt them parallel if there suppose to be serial as bolts can be nasty bugger if you get them wrong....

im lost, I think I know what you mean about offset, whats PCD?

and what do you mean by "when you put the 4 bolts back in make sure they are put in the right way ie dont bolt them parallel if there suppose to be serial"

How about looking on the internet ..

WHEEL OFFSET, PCD, and

CENTRE SPIGOT DIAMETER

Offset is the distance between the imaginary centreline of the wheel (as viewed from behind the wheel as it would roll away from you) and the inside face that bolts up against the wheel hub on the car. Fitting wheels that alters the track of your car (the distance between the centre of the left and right wheels, either front or rear) by more than 20mm will usually void any insurance policy, that means the offset cannot be any more than 10mm different per wheel than standard.

As an aside, the other two things to look for when fitting after market wheels is the PCD (Pitch Circle Diameter, ) and spigot size. The PCD is easy to match as this relates to the number of studs you need to hold the wheel on the car. The ACTUAL meaning is the diameter of the studs from the centre of the wheel.

Spigot size is a bit trickier....the spigot is the bit in the centre of the hub that you rest the inside centre of the wheel on whilst aligning the studs and !Removed! back the wheel nuts. On generic after market wheels, the spigot hole inside the wheels is a lot bigger than the spigot on the car. So what you need to do in this case is fit spigot locating rings. These are just rings of aluminium or hard plastic, that fit over the spigot on your car and then have a proper fit with the spigot hole on the wheel. If you don't have the spigot taking all the weight of the car, chances are you'll break one or more studs when you drive the car hard or have to brake hard. Remember the wheel nuts are simply there to hold the wheel on, NOT support the weight of the car. Also, as there is nothing to centre the wheel, you'll notice the wheels go in and out of balance because as you drive around, they'll move around on the hub.

Vmail, go into a shop, say what car u have etc, they will do rest.

If you dont know what pcd etc is, dont risk buying second hand

when bolting your wheels back on you should check the order with which you take the bolts out and put them back in....

failure to do so could end up blowing the wheel prematurely...

shoudl eb alright if you have a reciept though, you'ld be able to get the money back n the wheel and any damage caused although they may claim that the bolts were not fitted correctly....
