What are the biggest tires you can put on a stock 1997 Nissan Pathfinder?

The biggest tires you can install on your Nissan Pathfinder will depend on the specific configuration of your vehicle, such as the wheel size and suspension. However, here is a general guideline for tire sizes that may fit a stock 1997 Nissan Pathfinder:

265/75R16: This is a common tire size for the Nissan Pathfinder, providing a balance between on-road performance and off-road capabilities. It offers a slightly larger diameter than the stock tires and can provide improved ground clearance and traction.

285/75R16: Moving up in size, 285/75R16 tires offer a more aggressive look and slightly improved off-road performance. However, they may require minor modifications or adjustments to the suspension to ensure proper fitment and clearance.

265/70R17: If your Nissan Pathfinder has 17-inch wheels, you can consider installing 265/70R17 tires. These tires provide a larger diameter than the stock 16-inch tires and offer improved handling and stability on paved roads.

275/70R17: For a more aggressive stance and off-road capability, you can consider upgrading to 275/70R17 tires. These wider tires offer better traction and stability in challenging terrain.

When selecting tires for your vehicle, it's important to consider factors such as the wheel size, vehicle weight, and intended use (on-road, off-road, or mixed). It's always recommended to consult with a reputable tire shop or automotive professional to ensure proper fitment and safety.
