I have a 2005 e500 4matic with stock OEM17" alloy wheels. Currently 245 45 zr17 99w tires.

Can I switch to 18" x 8.5" chrome wheels with 245 40 zr18 93w tires, or will it cause a problem?

Thanks in advance for the help!

 

Yes you could,same rolling diameter.However you do not note the offset(ET)of the new rim or what it is off of.And chrome is not a good thing on mb that is why it is not a factory option.Chips,rusts and poor sealing,all make it a poor choice.

most after market companys only offer a one year warranty on chrome surfaces.

 

Ohlord, thanks! The ones I was thinking of were the wrong offset. You saved me a bunch of money!

 

Inkguy:
What is the ET of your 17" wheels?
If you go 18", I may have a use for them.
Let me know.
Thanks,
Dave
