W213 E Class 20 inch cracked alloy
Discussion
Hi All,
It appears that my 2017 W213 E Class has a cracked alloy. It is the rear, 20 inch, multi-spoke. Mercedes have quoted £900 for a replacement.
This seems a little expensive for a single wheel - has anyone had a similar problem and sourced an OEM wheel elsewhere?
Thanks in advance.

My previous E220d I ran for 3 years from new, 42,000 miles on standard 19inch wheels and not a single problem, although I do drive quite defensively and carefully. I have no idea about the previous owner from my current car...
The ride quality difference isn't that significant. If I run the 20inch wheels at the lower end of the recommended air pressure all seems pretty comfortable. Just spent 6 hours driving on a mixture of motorways, A roads and dual carriageways. Roads I know well and the ride seemed very similar to how I remembered by 19inch wheels on the same roads, back in March.

Thanks Stickleback.
I had 2 new rear tyres fitted this week, along with the new wheel. The other rear wheel was fine but I've not checked the fronts.
I'm not sure about pressures. One school of thought is that if the tyre pressures are on the hard side that doesn't allow much 'give' if you hit something, with the resulting shock load potentially damaging the wheel. On the other had, if the pressures are relatively low (but still within quoted parameters), this will allow the tyre to flex or give a bit more and therefore dissipate some of the shockloadings. Obviously, there is a tipping point and if I were going to drive at a kerbstone, at high speed, I'd probably want more, not less pressure!
The rears are 275/30/20. The fronts are 245/35/20. Om mt previous 220d with 19 inch wheels the profiles were the same.
The recommended pressures for the rears are 33 psi to 45 psi. I'm running at 35 psi for now....
