S204 w204 AMG Sport model c350 cdi 18 inch wheels and harsh ride?

[philnewmerc]

Hello. I've read quite a few older posts and it sounds like quite a few people reckon 17 in is better than the 18 inch this c350cdi amg sport came on, in terms on reducing harshness a bit. Since it needs new tyres i wondered about buying some 17s on ebay but i am unsure if I need to consider offset? (I've never changed wheels before.) The tyres on it are 255 35 18 on the rear and 225 40 18 on the front. Do i need staggered 17s or will ones with the same tyre width front and rear be ok?
Cheers

The ride on my 2013 204 on 16" is sublime!

My S204 came on 16's and I found the ride/drive a bit wallowy, changed to 17's and the ride is still comfortable but it drives better. I have a staggered set-up, 7.5J fronts with 225/45 tyres, 8 (or is it 8.5)J rears with 245/40 tyres - except that I could not find that size all season tyres so fitted 235/45 instead, which works OK.
Have a look on alloywheelsdirect.net for wheel size/specs for your car, ET number is the offset, full spec will read something like 17 x 7.5J ET... 5x120.

Do 17's clear the front brake calipers on a 350 Sport?
Not saying they don't, just something to check.
