Changing w210 tyre size

[M.A.94]

Is there any real problem with down sizing tyre sizes. I have the staggered 18 inch AMG monoblocks 8j and 9j

Original tyre size was (iirc):
265 35 18 rear
235 40 18 front

Since lowering my car to avoid the tyres rubbing the arches I have gone down to:

255 35 18 rear
225 35 18 front

I'm not talking about issues such as reduced comfort, higher chance of curbing wheels, Speedo slightly off..

It's more mechanical things such as abs etc. I ask this because I remember reading something relating to this year's ago but can't find the thread. At the moment I've not had any warning lights just the occasional traction control light when I pull of a bit quick which is normal as the rear wheels are losing grip.

Also consider invalidating your insurance, unless you've already declared the change.

Insurance knows wheels have been changed on car..

Fronts should be 40 profile.

I know the original spec for the tyres from factory. I just want to know how these effect abs etc by changing tyre sizes.
