Would a wider rear wheel/tyre improve wet weather grip?
Every other Mercedes owner I speak to confirms that the cars can be difficult in the wet and impossible in snow, although I find that mine is better if I keep my foot in and don't back off.
Wider rims and tires will not improve wet weather grip...My car is useless with the 215/45-17 tires in the snow! I can get nowhere when it is snowing and I am still running the 17 inch wheels.
I have said it before and will say it again: you need to have your wheel balanced to get rid of the vibrating steering wheel.
