CLK 2009 18” Alloy Wheels

[Paco42]

Hi, I’m new here and having a nightmare getting 18” alloys onto my 2009 CLK.

These links look great, but think Ineed help from people with experience!

I’ve tried spacers today; rears went on great, but no-go for the fronts as bolts too long.

Also, I realised new bolts won’thave a locking wheel nut.

Can anyone help please?

Thank you!

Are you sure you didn't put the rears on the front by mistake. What size tyres are fitted . Also check the offsets, should be embossed on the rear of the wheels spokes etc.

I let a professional take care of it who tried everything with all 4 wheels.

What offset do I need to be checking on mine?

You need ET 36 front and ET 30 rear on 18" OEM alloys.
They should also be 7.5j front and 8.5j rear.

W211 E class wheels should also fit.
You can have all kinds of problems if they are arftermarket wheels or OEM with the wrong offset as you are finding out.

Amazing. Thanks for your reply.

I think I’m just going to try and find a shop that sells them and pay a bit extra

Make sure you get Mercedes fitment and preferrably OEM.
eBay often have some good sets but ensure you get the correct offsets within a few mm.
The higher the offset above the recommended ET the more the wheel will sit closer to the caliper.
Conversely, if the ET is lower, it will sit closer to the wheel arch.

I’m an idiot, but what does ET stand for?

The ET is the offset, which you will find on the inside of every OEM alloy.

Morning. Meant to ask, what does ‘7.5j’ and ‘8.5j’ mean?

Cheers.
