Less than a quarter of an inch bigger in diameter, depending on what wheel you are running, the most likely spot to watch out for would be the front upper ball joint as far as contact point.
Do you have 7 or 8 inch wide wheels? I think that width of tire is good for 7 inch wide wheels (it is what current Mustangs and Crown Vics with the 17 inch Sport wheels run).
