I have measured the larger stud gap and believe these are 5x112 using this guide: https://www.mwsint.com/site/cms/contentviewarticle.asp?article=661 and included a picture so you can check this out yourself.

I have measured the offset and have got this to be approx ET38

The wheels are in good, used condition, some minor marking.

Tyre 1 - 6mm Worn on the edge

Tyre 2 - 6mm

Tyre 3 - 5mm Some small cracking between the tread

Tyre 4 - 5.5mm 

I'd just like to try and get back what these owe me.

Cash on collection only please.
