hi

use this calculator to work out the difference between your original wheels and any new ones you may be considering.

once you have done the calculation just go out and check on your car if there is enough clearance with the new dimensions as calculated.

remember the calculator is only for the rim, if you are going to use a wider tyre then don't forget to adjust the calculated figures to suit.

hope this makes sense and helps you out.
