Tire sizes by trim

Recommended replacement tires

The 2019 Chevrolet Suburban is a versatile SUV, and its tire needs can vary based on driving style and conditions. Here are some popular replacement options:

• Michelin Defender LTX M/S (Premium Tier): A long-time favorite for trucks and SUVs, offering excellent all-season traction, a comfortable ride, and exceptional tread life. Expect to pay around $200-$250 per tire.
• Goodyear Wrangler SR-A (Mid-Range Tier): Often an OEM tire, this option provides a good balance of highway comfort, all-season grip, and a reasonable price point. Generally costs $160-$200 per tire.
• Kumho Crugen HT51 (Value Tier): A solid all-season highway tire that delivers good performance in various conditions and offers a quiet ride, all without breaking the bank. Typically priced around $130-$170 per tire.

When to inflate to max load psi

The 2019 Chevrolet Suburban is not a heavy-duty (HD) truck. Therefore, you should never inflate your tires to the "max load" PSI listed on the tire's sidewall. This pressure is intended for commercial or heavy-duty applications and would result in an overly harsh ride, premature tire wear, and potentially unsafe handling for your Suburban. Always adhere to the recommended cold tire pressure listed on your vehicle's door placard.

Lug nut torque & pattern

For the 2019 Chevrolet Suburban, the lug nut torque specification is 140 lb-ft (190 Nm). Always tighten lug nuts in a star or crisscross pattern to ensure even seating of the wheel against the hub. This helps prevent warping of the brake rotors and ensures the wheel is securely fastened.

Common tire issues for this vehicle

Owners of 2019 Chevrolet Suburbans occasionally report a few common tire-related issues:

• Uneven Tire Wear: This can be exacerbated by neglecting tire rotations, improper alignment, or incorrect tire pressure. Regular rotations every 5,000-7,500 miles and annual alignments are crucial.
• Vibration at Highway Speeds: This often points to unbalanced tires. Even new tires can benefit from balancing, and it's especially important after tire rotations or repairs.
• TPMS Sensor Malfunctions: While generally reliable, TPMS sensors can sometimes provide inaccurate readings or fail. This can be due to battery issues (although less common on a newer vehicle), sensor damage, or programming issues after tire service. If you have a TPMS warning, it's best to have it diagnosed by a professional.
• Rapid Tread Wear: Aggressive driving habits, improper tire pressure, and misaligned suspension can all contribute to tires wearing out faster than expected. Choosing tires with a higher treadwear rating can also help.
