pcd measurments
Discussion
Hey All,
I bought 18 inch VXR alloy wheels that I was told fit my 2011 Astra J, they dont.
I think they are actually corsa vxr wheels which have a different pcd to the astra. I have found a company, Superforma, based in Devon that will make custom wheel adapters but obviously require specific measurements.
I am not able to take such measurements, I am not competent or confident enough to know what i am doing and I do not want a set that doesnt fit.
Does anybody know where I can get my wheel measurements done accurately, or even a place around Manchester (where I live) that provides wheel adaptor services?
Thank you

Adapters will need to be around 20mm thick for them to work correctly and be safe. Will your wheels still work with that size adapter? You might find they stick out.
I believe so, the wheels I have on now are 19's and fit fine, even with my car lowered 40mm. There is still plenty of space between the arch and the top of the tyre. I have always liked the "wide stance" too
Do you absolutely have to use these specific wheels as opposed to selling them and buying some that are correct for the vehicle?
You can measure the PCD and bold/stud pattern fairly easily.
Establishing the hub center fitment takes more care but should be possible to work out once you have identified the car they actually fit.
You also need to get the inset right. This will determine whether the wheel is in the right position relative to the bearing and braking forces on it so it very important. It will also determine whether the wheel clears the bodywork and suspension.
You will also need to confirm the wheel has enough internal clearance for the hub, upright and brakes.
It's not rocket science but there are plenty of ways to go wrong.

Exactly, a science I am not good with. You can measure the PCD and bold/stud pattern fairly easily.

I bought the wheels at a good price and had them refurbished. Selling them I would lose at least half, putting me at £200 and at the moment decent vxr wheels for astra are around £400 upwards.
wheel adapters would set me back about £200, if i can get the pcd measurements correct.
Jaysus. Have you any idea how inept this all sounds? There are tables of pcd dimensions online for every car ever made. The VXR is 5 x 110 mm and the Astra is 5 x 105 mm.

You even got them refurbished before checking they actually fitted?? And you can't use a ruler for a simple measurement? Heck, what skill set do you actually have?
Get a ruler, measure from the exact centre of the wheel to the centre of any bolt hole. That's the pitch radius so double that measurement for the PCD.
If it's hard to find the exact centre of the wheel then measure the diameter of the central hole, measure from a bolt hole to the near edge of the central hole, double this measurement and add the central hole diameter to get the PCD. Buy a cheap digital vernier on Ebay. It'll come in handy for lots of other stuff.
