ok,
1. check out the clearance on the top of the tire to the bottom of the strut base.
2. crank the steering hard left and right and see how close you are to anything.
3. if the is clearance get back with a rough estimate.
4. then will look at tirerack.com for the next size taller

see post/pics at #30. That is the clearance to the strut mount WITH the taller tire!
However, the way the fender well was designed, there is about 1/4 of an inch at the front edge.
So that was the tallest tire i could go with!
