1. Increased traction: Larger tires have a larger contact patch with the ground, which provides more surface area for the tires to grip the road. This can be especially beneficial when driving off-road or in wet or slippery conditions.

  2. Improved handling: Larger tires can also improve the handling of a 4x4 by providing a softer ride and better absorption of bumps and potholes. This can help to make your 4x4 more comfortable to drive and reduce wear and tear on the vehicle.

  3. Better clearance: Larger tires can also increase the clearance of a 4x4, which is the distance between the bottom of the vehicle and the ground. This can be beneficial when driving off-road, as it can help to avoid getting stuck in mud, sand, or other types of terrain.

  4. Increased towing capacity: Larger tires can also increase the towing capacity of a 4x4, as they can provide more stability and support for heavy loads. This can be beneficial if you plan to use your 4x4 for towing a trailer, boat, or other types of equipment.

  5. Better appearance: Larger tires can also enhance the appearance of a 4x4, making it look more aggressive and sporty. This can be especially beneficial if you're looking to customize your 4x4 and make it stand out from the crowd.

It's important to note that increasing the tire size also have some downsides such as affecting the speedometer reading, additional fuel consumption, and the possibility of not fitting in the wheel wells. It's essential to consult with a professional and check the vehicle manual before making any changes to the tire size.
