    Tire size for 3-4 drop on c30

    Just purchased a 3-4 drop kit for my c30 from switch suspension. My truck has a th400 with a d70 with 4.10 rear gears. With that being said my concern is reving too high with small tires. Looking for what tire sizes yall are running with these kits. Photos would be appreciated.
