2022 Chevrolet Suburban — Tire Size & Pressure Guide

As an ASE-certified master technician, I’ve seen my fair share of 2022 Chevrolet Suburbans roll into the shop. Whether you are prepping for a cross-country family road trip, getting ready to tow a heavy load, or just dealing with a standard tire rotation, knowing your vehicle's exact tire and wheel specifications is crucial for safety and performance. Here is your comprehensive guide to the 2022 Chevy Suburban’s tire sizes, pressures, and wheel specs.

Quick answer

• OEM tire size: 265/65R18, 275/60R20, or 275/50R22 (depending on trim)
• Recommended cold tire pressure: 35 PSI Front / 35 PSI Rear (Check driver's door jamb placard)
• Bolt pattern: 6x139.7 (6x5.5")
• Wheel size: 18x8.5, 20x9, or 22x9
• Load index/speed rating: 114T to 115S/111H (varies by size)
• Spare tire size: 265/70R17 (Full-size spare on steel wheel)
• TPMS frequency: 433 MHz

Tire sizes by trim

The 2022 Suburban is offered in multiple trims, from the base LS to the luxurious High Country and the off-road-oriented Z71. Here is a breakdown of the standard and optional tire sizes.

Note: Optional 22-inch wheels are available on LT, RST, and Premier trims as an upgrade.

Recommended replacement tires

When it is time to replace the rubber on your Suburban, you need a tire that can handle the sheer weight of this full-size SUV while delivering a smooth, quiet ride. Here are a few technician-approved recommendations:

• Michelin Defender LTX M/S (Premium) - Exceptional tread life, fantastic highway manners, and great wet traction. Ideal for family haulers.
• BFGoodrich All-Terrain T/A KO2 (Premium) - The go-to choice for Z71 owners or anyone looking to tackle rougher trails without sacrificing too much road comfort.
• Falken Wildpeak A/T3W (Mid-Tier) - A fantastic all-terrain option that punches above its weight in snow and rain, at a slightly more affordable price point.
• Cooper Discoverer HT3 (Mid-Tier) - A solid, reliable highway-terrain tire that offers a quiet ride and good longevity for the budget-conscious driver.

When to inflate to max load psi

While the 2022 Suburban is a half-ton class SUV and not a heavy-duty (HD) truck like a Silverado 2500, it still boasts impressive towing and payload capacities. For normal daily driving, always stick to the 35 PSI listed on the driver’s side door placard.

However, if you are maxing out the vehicle's payload (loading up all three rows and cargo) or towing a heavy trailer near the 8,300-lb max capacity, you should inflate the rear tires closer to the maximum cold pressure listed on the tire sidewall (usually 44 PSI for standard load tires). This reduces sidewall flex, minimizes heat buildup, and provides better towing stability. Always drop the pressure back to 35 PSI once you are done towing to avoid a harsh ride and uneven center tread wear.

Lug nut torque & pattern

Proper wheel installation is a matter of safety, especially on a heavy SUV.

• Bolt Pattern: 6x139.7mm (6x5.5 inches)
• Lug Nut Size: M14 x 1.5
• Lug Nut Torque Specification: 140 lb-ft (190 Nm)

Tech tip: Always use a calibrated torque wrench. Do not rely on an impact gun. Tighten the lug nuts in a star/crisscross pattern to ensure the wheel seats evenly against the hub. Re-torque after 50 to 100 miles of driving following a wheel removal.

Common tire issues for this vehicle

1. Outer edge wear: Because the Suburban is a heavy vehicle with a high center of gravity, aggressive cornering can quickly scrub the outer edges off the front tires. Regular rotations (every 5,000–7,500 miles) are mandatory.
2. TPMS Sensor failure: While the 433 MHz sensors are generally reliable on the 2022 model, the batteries will eventually die (usually around the 5-7 year mark), or the aluminum valve stems can corrode if you live in the rust belt.
3. Cupping/Scalloping: If the rear shocks begin to fail (especially on models with standard suspension, less so on Magnetic Ride Control setups), you may notice a loud hum from the rear tires caused by tread cupping.
