size or brand

Hi MB enthusiasts, I have a S320 CDI on a 04 plate automatic. and need to buy new tyres. looking at the tyres on the car at the moment they are all the same size. When I look on the web sites the front and rear are supposed to be two different sizes. Question: does anyone know, or can tell...

Hi all. I've recently got a Ml270 (my first Merc) and I'm a little disappointed with the general ride quality. The suspension and steering has been given the once over and all seems OK so I'm wondering if a change of tyre make and/or size could improve things and would appreciate some opinions...
