The term "running bigger tires" is a common one with off-roading enthusiasts since larger, taller Wrangler JK rims and tires are required to conquer challenging terrain. Upsizing from the regular stock wheels, which are 15 inches in diameter, owners can select 16, 17, or 18-inch Jeep Wrangler JK wheels. Not only will these wheels help your ride a bit higher, they will also support the much bigger, heavier tires that are needed to power you through the mud, muck, and snow. The size of the Jeep Wrangler JK wheels you need depends on the type of off-roading activities you enjoy. As a general rule, the more likely you are to get stopped or stuck, the bigger the wheel and tire set you will need. Drivers who participate in mud bogging, for instance, need oversized tires to get them through rough patches. A locker and lift kit are also essential additions for any serious off-roader.
