Hey Guys i need your help. At the moment i will get my car back on the road but i need some technical Details about my Stock rims in Point of the offset.
Now on my Blazer are installed 275/45/20 with 40mm wheel spacer per side.

So now my TÜV service Engineer told me that he will take over the 20" in to my registration certificate but he will see an Document where it shown what kind of Offset this stock rims have. I put a picture of this rims as an Attachment. So I hope you can help me out. Thanks a lot

Use a ruler and measure from the wheel mounting surface to the lip of the rim on the back side of the rim. I'm not sure on the width of those, but I'm pretty sure 2 wheel drives have 4.5" of backspace, I'm not sure what that makes the offset, maybe 0?

 

Thanks for the Information. I know how to measure the offset. But i need a document where it shown the size. Because it make it more easy for me to show this to the technical inspector in Germany.
You have to know Germany is very stupid in such a points.
Thanks

 

it seems from the searching I did that they only care about offset that side of the pond
It also seems that all the charts I did find forgot about chevrolet

Does your vehicle have the original owners manual in the glove box
Sometimes there is technical specs in the owner manual

Another place to look would be a Haynes repair manual, again sometimes they have that type of technical data

I looked @ www.tirerack.com ,it does show offset for some of the wheels available but it varies

I would be suprised if the inspector did not have issue with the wheel spacers BTW
