When to Inflate to Max Load PSI

Common Tire Issues for This Vehicle
The Jeep Wrangler's solid front axle design can make it susceptible to what is commonly known as "death wobble" if suspension or steering components are worn or improperly installed. While not a tire issue in itself, it is often felt as a violent shaking of the front wheels and steering wheel. Ensuring proper tire balance and alignment is crucial, especially when running larger, heavier aftermarket tires. Regular inspection of steering and suspension components is highly recommended.
