All-terrain (A/T) tires are the best all-around choice with moderate tread blocks that perform well on pavement, gravel, light mud, and packed dirt. They last 40,000-60,000 miles and are relatively quiet on highway. Mud-terrain (M/T) tires have aggressive, deep tread blocks with wide voids designed for deep mud, sand, and rocks. They are louder on pavement and wear faster (25,000-40,000 miles) but provide far superior off-road grip.

All-terrain tires typically last 40,000-60,000 miles with regular rotation every 5,000-7,500 miles. Mud-terrain tires last 25,000-40,000 miles due to softer compounds and more aggressive tread. Factors that reduce life include low tire pressure on pavement, alignment issues, and aggressive driving. Including the spare in a 5-tire rotation maximizes tread life.

No. All four tires (and ideally the spare) must be the same size and type. Mismatched tires cause differential stress in 4WD, uneven braking, and potential transfer case damage. If you damage one tire beyond repair, it is best practice to replace it with the same brand, model, and size.

On pavement, follow the door sticker recommendation (32-36 PSI for most Jeeps). For general trail driving, air down to 22-25 PSI for better traction and ride comfort. For rock crawling, 15-18 PSI provides maximum grip. For deep sand, 12-15 PSI. Always carry a portable air compressor to re-inflate before returning to pavement.
