2024 Chevrolet Suburban — Tire Size & Pressure Specs

As an ASE-certified master technician, I regularly service full-size SUVs like the 2024 Chevrolet Suburban. Whether you are hauling the family across the country or towing a boat to the lake, maintaining the right tire size, pressure, and tread depth is critical for the safety and performance of this heavy, body-on-frame vehicle.

Below is your comprehensive reference guide for the 2024 Chevrolet Suburban’s tire and wheel specifications.

Quick answer: 2024 Chevy Suburban Tire & Wheel Specs

• OEM Tire Sizes: 275/65R18, 275/60R20, or 275/50R22 (depending on trim)
• Recommended Cold Tire Pressure: 35 PSI Front / 35 PSI Rear (Check door placard for your specific trim/package)
• Bolt Pattern: 6x139.7 (6x5.5")
• Wheel Sizes: 18x8.5, 20x9.0, 22x9.0 (Offset typically +24mm to +28mm)
• Load Index / Speed Rating: 116T or 115T (Standard Load or Extra Load depending on tire size)
• Spare Tire Size: 265/70R17 (17-inch steel spare wheel)
• TPMS Frequency: 433 MHz

Tire sizes by trim

The 2024 Suburban is available in several trims, ranging from the base LS to the luxurious High Country and the off-road-focused Z71. Here are the factory tire sizes for each:

Note: The Z71 trim features a slightly different suspension and front fascia to accommodate aggressive all-terrain tires.

Recommended replacement tires

When it's time to replace the rubber on your Suburban, you want tires that can handle its 5,800+ lb curb weight while providing a quiet ride. Here are my top picks across different price tiers:

1. Michelin Defender LTX M/S (Premium / Highway)
   • Best for: Long highway trips, daily driving, and towing. Outstanding tread life and wet traction.
2. BFGoodrich All-Terrain T/A KO2 (Premium / All-Terrain)
   • Best for: Z71 owners or those who frequently drive on unpaved roads and need severe snow rating (3PMSF).
3. Falken Wildpeak A/T3W (Mid-Range / All-Terrain)
   • Best for: An excellent balance of on-road manners and off-road capability at a slightly lower price point than the BFG.
4. Kumho Crugen HT51 (Budget / Highway)
   • Best for: Drivers looking for a comfortable, reliable all-season tire without breaking the bank.

When to inflate to max load psi

While the 2024 Suburban is a standard half-ton equivalent SUV (not a Heavy Duty 2500/3500 truck), it has substantial towing and payload capacities. The door placard recommends 35 PSI for normal driving conditions.

However, if you are towing a heavy trailer near the max capacity (up to 8,300 lbs) or carrying a full payload of passengers and cargo, you should consider increasing the rear tire pressure to 39–41 PSI to reduce sidewall flex and improve stability. Never exceed the maximum pressure listed on the tire's sidewall (typically 44 PSI or 51 PSI for standard P-metric and LT tires, respectively). Always check your tires cold before hitting the road.

Lug nut torque & pattern

Proper wheel torque is absolutely vital on heavy SUVs to prevent warped brake rotors and wheel detachment.

• Bolt Pattern: 6x139.7mm (6x5.5")
• Lug Nut Torque: 140 ft-lbs (190 Nm)
• Socket Size: 22mm (7/8")

Always use a calibrated torque wrench, tighten in a star pattern, and re-torque the lug nuts after 50–100 miles of driving following a wheel installation.

Common tire issues for this vehicle

1. Outer Edge Wear: Because the Suburban is a heavy, tall vehicle, aggressive cornering often leads to premature wear on the outer shoulders of the front tires. Regular rotations (every 5,000 to 7,500 miles) are mandatory to even this out.
2. Cupping and Feathering: If the front shocks begin to wear out, or if the alignment is knocked out of spec by a pothole, the heavy front end can cause tire cupping (scalloped wear). Have your alignment checked once a year.
3. TPMS Sensor Battery Failure: While less common on a brand-new 2024 model, the 433 MHz TPMS sensors typically last 5-7 years. If you are buying a used set of winter wheels, make sure the sensors are fresh and synced properly using a TPMS relearn tool.
