I'm really not trying to beat a dead horse here but I just have to chime in. I'm not a huge fan of rolled fenders. I'll roll mine if I need to, but only after testing. My career is focused on supporting data driven decision making so I am quite the fan of testing and using data when it is appropriately available.
Better safe than sorry on a CSL means *not rolling the fenders if you don't need to. It is very easy to roll a fender and very difficult to "unroll" one. It costs what - $15 to $20 to mount (and balance) a tire? Go to your tire store and have them mount a 225 tire. Install the wheel and articulate the suspension. It's pretty easy for the rear, if you have room on the outside when sitting, you should have room when compressing the suspension. That is because the trailing arm will arc upwards away from the fender lip.
The movement applies to the front, however you are adding in the movement of the wheel. Articulate the suspension with the wheel at partial and full lock. If you have a lift, you can do this with a block of wood under the tire. If you don't have a lift, stick a floor jack under the tire, or a bottle jack on the trailing arm.
