Description
Mounted and Balanced Wheel and Tire Kit. This wheel and tire combo kit features (4) 17x9 Mammoth Synister Charcoal Wheels and (4) NITTO Mud-Terrain Trail Grappler M/T 315/70R17 tires that have been put together into an easy to buy kit that arrives to your door already mounted and balanced ready to be installed on your vehicle.
Charcoal Mammoth Synister Wheel. Mammoth's Synister Wheel offers rugged styling with its unique 8-spoke design and embossed accents around the circumference of the lip. This Wheel is completed in a high quality, clear coated, charcoal gray finish for an aggressive appearance that can withstand the hazards of everyday driving - including road chips and pitting. This Mammoth Synister Series Wheel is perfectly suited for both street and off-road applications.
NITTO Mud-Terrain Trail Grappler M/T. The Trail Grappler M/T provides an aggressive mud tread design with on-road quiet ride performance. The 3-ply sidewall and thick rubber construction increase puncture resistance. Leading edge tread and side lug blocks provide additional biting edges that command lateral stability and enhance forward traction. Each Grappler has two sidewall designs so you can choose how your tires look. On the Trail Grappler one side has stylized lettering with V-shaped sidewall lugs and the other has traditional lettering with flat buttresses. A common complaint with mud terrain tires is their noise level. Nitto's engineers set out to design an aggressive -- and yet quiet -- off-road tire. Using 3D computer simulation, Nitto's engineers were able to systematically adjust the size, shape and position of the tread blocks. As a result, Nitto produced an off-road tire that is 34% quieter at street speeds and 36% quieter at highway speeds.* *Compared to Nitto Mud Grappler. The 3-ply sidewall with a high turn-up construction acts as an extra layer of reinforcement to increase puncture resistance. Nitto’s proprietary, automated manufacturing system produces extraordinarily uniform tires. This creates a smooth ride on paved roads. Reinforced shoulder grooves add additional off-road and all-season performance without compromising tread block stiffness. Deep center sipes decrease hydroplaning and increases traction in wet conditions. The balanced void ratio efficiently removes mud and dirt from the tread to provide continuous off-road traction.
How do I keep my TPMS feature? The Tire Pressure Monitoring System is a safety feature found on all modern vehicles that alerts you when your tire pressure drops to an unsafe limit. Aftermarket wheels do not have TPMS sensors. However, if you select 'Add TPMS Sensor Kit' for your specific year from the options listed above, we'll install the sensors in your new wheels for free!
Application. This 17x9 Mammoth Synister & NITTO Mud-Terrain Trail Grappler M/T Tire Package is designed to fit 2020-2025 Jeep Gladiator JT models.
Road Hazard Protection. ExtremeTerrain is proud to offer an optional Road Hazard Tire Protection program to our customers who purchase a Wheel and Tire Package from us. With this program, you will receive a 3-Year/36 Month protection plan for changing of flat tires and flat tire repair.
36 Months of Protection. The Road Hazard Protection Program is good for 3-Years (36 Months) from the purchase date printed on the program certificate or until any part of the tire tread that comes in contact with the road has a tread depth of 2/32” or less, whichever comes first.
Flat Tire Changing Assistance. Enrolled customers are eligible for reimbursement of up to $75 for roadside flat changing assistance provided by a licensed service provider. This is limited to the roadside installation of the customer’s own usable spare tire. Customer must have a spare tire. The customer would pay the service provider for flat tire changing and then be reimbursed.

Reimbursement is limited to two flat tire repair claims during the coverage terms of 3-Years/36 months. The customer would pay the service provider for flat tire repair and then be reimbursed.
