9.0 20INCH Alloys W204 - Help

[rushh]

Hi Everyone,

I was wondering if anyone could help me, I am currently running
W204 C Class C250CDi 2010 on..

Front wheels 8J x 19 ET 45 - tyre size is 235/35 R19
Rear wheels 9J x 19 ET 54 - tyre size 255/30 R19

I am planning on buying 20Inch Alloys with the following spec's

Front wheels 9J x 20 - tyre size is 9.0 225/30/20 Stretched
Rear wheels 10 or 10.5 x 20 - tyre size is 10 or 10.5 245/30/20 Stretched

My question is, would 9J on the front wheels be OK? if so what offset would I need?

Second question is can I fit 10.5 on the rear if so what offset would I need?

I know people on here do not like 20" but its what im happy to have on my C Class I'm only on here for help, could someone kindly advise me, it would be greatly appreciated.

Thanks,

Rushh

The sticky threads at the top of the wheels, tyres & suspension page should give you some pointers.....

Hi Rushh,
Was running 20" x 8.5J Fronts and 20"x 10J Rears on my SL, bodykitted up etc, main point from experience, the 30 Profile and the extra width increases the likelihood of the inner rim cracking. Had 2 ruined wheels within weeks and 4 PZeros scrapped. Expensive mistake, nothing to do with quality of wheels, just simply the state of the roads. Went to 19's on the front, 35 profile, better but not perfect, ended up back on the 18's. Hope this helps.
