Tirerack's Spec's section gives the wheel width range for each tire. Click on a specific tire and a Spec tab normally shows up.
I would also check your exiting front tire clearance to the inner fenders at extreme lock. A larger diameter tire may scuff the inner fenders in parking lot maneuvers. Normally not a big deal, but something to consider. And be sure they'll clear the spring perches on the shock towers too.
