The Cooper Discoverer Rugged Trek is a rugged all-terrain tire built for tough conditions in pickup trucks, SUVs, and off-road-oriented vehicles. With an aggressive tread design and durable construction, it excels in mud, rocks, gravel, and loose surfaces while still offering respectable on-road manners for daily driving.

Deep tread features and strong sidewalls provide excellent off-road traction and puncture resistance. The tire delivers confident performance in dry, wet, and winter conditions, making it suitable for work trucks, adventure vehicles, and weekend explorers. For owners of electric trucks and adventure-ready electric SUVs, the Discoverer Rugged Trek offers the robust build needed to handle instant torque and higher vehicle weight.

Choose this tire when you need serious off-road capability paired with everyday drivability for both traditional and electric off-road vehicles.

Checking and Adjusting Tesla Tire Pressure

When your Tesla has been stationary and out of direct sunlight for over three hours:

• Remove the tire air valve stem cap (unscrew cap by hand).
• Firmly press a tire pressure gauge onto the valve stem tip to measure pressure (a small amount of air will escape during measurement, which is normal).
• Compare reading to Tesla Tire Pressure specification (found on the Tire and Loading Information label located midway up on the center door pillar, visible only when the driver’s door is open), add or remove air to match the recommended pressure. Reduce pressure by by pressing the metal pin in the center of the valve. Increase pressure using an appropriate tire inflator pump or compressed air source.
• Re-check pressure using the tire pressure gauge.
• Re-install the valve stem cap (hand tighten)
• Important note: Under-inflation is the most common cause of tire failures and can cause a tire to overheat, resulting in severe tire cracking, tread separation, or blowout, which causes unexpected loss of car control and increased risk of injury. Under-inflation also reduces the car's range and tire tread life.
• Tesla TPMS sensors require driving for a short period of time before updated pressure readings are recorded accurately. Expect TPMS readings to reflect accurate tire pressure readings after driving 5 miles.

Factors impacting tire pressure readings:

• Ambient temperature - Air pressure increases in heat and decreases in cold.
• Tire temperature – Tires warm up during use.
• Sunlight – directly sunlight will increase tire temperature and thereby tire pressure.
