I had to do about a 1/2" trimming on the front lower cladding, but others with the same tires didnt seem to have to. It probably depends on your method of driving. I am pretty aggressive so I get the max use out of cornering/turning and I found that I had some rubbing. The trimming is completely unnoticable, even if I were to point it out. Very flush job with a hacksaw and a file.

It's hard to say what tire size to get. It really depends on YOUR preferance. I plan on going wider as soon as I get my new wheels, and I may stick with the Yokos. A very soft tire with a lot of good grab. Not so good in snow though.
