      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 2020-2026 Jeep Gladiator JT models.
