I recently purchased a C Class 2014 (W205) Bluetec Sport Premium.
I've just noticed that the tyre sizes on the front are the same as on the back?!
They're both 225/50 17 Y.
I thought rear wheel drive vehicles had bigger/wider tyres on the back as was evident in my last C Class...
I've been holding off until the good weather landed to get my wheels either refurbished or replaced. I just found an almost new OEM set of alloys from a W205 for sale that I'm hoping will fit my W204 C350 D.
Their sizes are:
