When choosing correct tires for a Jeep JK do be aware whatever you choose will most likely be a compromise between the main use of the vehicle, like on road, and occasional use such as some off roading. If the difference is too great then having 2 sets would be a better way to go.
Tire choice will affect drive-ability, gearing, gas mileage, wear on suspension and steering and more. Modifications may be required to suspension and body for clearance, and in extreme cases will be necessary to trailer the vehicle on road.
