Is it possible to have to much tyre width? The reason behind my question is when I first put 17 inch wheels on my 230ce I had all sorts of steering problems that could not be resolved (the main one being that the cars front wheels wanted to folow every rut and undulation on the road) I finally got rid of this by changing the front tyres to 225's. However I didnt pay attention to the width that came off, and simply put the problem down to bad tyres. However I now have the same issue on the 320ce since having new 245's all round. So is it possible that thats just to much tyre for the vehicle?
