time for new tires, wheels too.... opinion
 

I have a 2005 C240 4matic. And it is now time for new tires... Since i am getting new tires, thought why not get new wheels too :D my question is, I am slightly interested in upgrading to an 18" wheel. But i have heard, that by doing so, you will feel every little pebble in the road. so i am looking for your opinion, personal experiences... etc... thank you in advance :o
