Mine rubbed the tire at about a full lock turn.
I loosened and rerouted both hoses to keep them from touching anything without shortening or lengthening them.
Pay attention though that the axle pivoting at the center does not cause the hoses to touch anything at full articulation.

I routed mine exactly as kylew did. I'll send a pic, unfortunately I just got off the tractor an hour ago and was cutting in a very high grass, wet and muddy area on my property, so dirty pic...

The hoses on mine ended up just barely clearing everything. Certainly even a half inch shorter would have helped.
I think, but no proof, that Deere sold a couple years run with the hoses like this before fixing it somehow at the factory.
I saw my tire contacting mine before it had done any serious abrading and got under there and fooled with it.
