2020 Volvo VNL Tire Size, Pressure & Wheel Specs

As an ASE-certified master technician, I regularly see Class 8 heavy-duty trucks rolling into the bays, and the 2020 Volvo VNL is a prime example of a premium highway hauler. Proper tire maintenance on a commercial truck of this size isn’t just about fuel economy—it’s a matter of critical safety and compliance. When your rig is grossing 80,000 lbs, having the correct steer and drive tires at the right pressures is everything.

Below is your comprehensive guide to the tire and wheel specifications for the 2020 Volvo VNL.

Quick answer: 2020 Volvo VNL Tire & Wheel Specs

• OEM Tire Size: 295/75R22.5 or 11R22.5 (Steer and Drive positions); optional wide-base 445/50R22.5 for drives.
• Recommended Cold Tire Pressure (Front/Steer): 105–110 PSI (check door/B-pillar placard and tire load charts based on actual steer axle weight)
• Recommended Cold Tire Pressure (Rear/Drive): 95–100 PSI (duals, standard load)
• Bolt Pattern: 10-lug Hub Piloted (10x285.75mm)
• Wheel Size & Offset: 22.5" x 8.25" (Standard) or 22.5" x 14.00" (Wide Base / Super Singles)
• Load Index / Speed Rating: Typically 144/141 or 149/146 (Load Range G or H / 14-ply or 16-ply). Speed rating L (75 mph) or M (81 mph).
• Spare Tire Size: Commercial tractors typically do not carry a spare from the factory, but roadside replacement size matches the mounted steer/drive (295/75R22.5).
• TPMS Frequency: 433 MHz (If equipped with factory Bendix SmarTire or similar commercial TPMS).

Tire sizes by configuration

While commercial trucks don't have "trims" like passenger cars, the VNL is ordered with specific axle and wheel configurations based on fleet needs (VNL 300, 400, 740, 760, 860).

Recommended replacement tires

When replacing tires on your 2020 Volvo VNL, ensure you are buying application-specific tires (Steer vs. Drive). Using a drive tire on a steer axle is highly discouraged and often unsafe.

• Michelin X Line Energy Z (Steer) / Energy D (Drive) — Premium ($$$$): The gold standard for long-haul fuel efficiency and long tread life. Excellent casing for retreading.
• Bridgestone R213 Ecopia (Steer) / M713 Ecopia (Drive) — Premium ($$$): Outstanding low rolling resistance and fantastic wet traction. Highly popular for regional and long-haul VNLs.
• Goodyear Endurance LHS (Steer) / LHD (Drive) — Mid-Range / Premium ($$$): Extremely durable with uniform wear patterns, designed to handle the heavy steer axle weights of modern aero-trucks.
• Yokohama 114R (Steer) / 712L (Drive) — Economy / Mid-Range ($$): A highly dependable, cost-effective option for owner-operators looking to balance upfront cost with reliable mileage.

When to inflate to max load psi

Because the 2020 Volvo VNL is a heavy-duty commercial truck, tire inflation is entirely dependent on axle weight rather than a single arbitrary number.

You should inflate your tires to the maximum cold pressure listed on the tire sidewall (often 110 or 120 PSI for Load Range H) only when your axle weight demands it according to the tire manufacturer's load/inflation tables. For example, if your steer axle is carrying 12,000 to 13,000 lbs, you generally need 105-110 PSI to safely support that weight. Under-inflating a heavy steer tire builds excessive heat and can lead to a blowout. However, running max PSI on an empty truck (bobtailing) will result in a harsh ride and rapid center-tread wear. Always weigh your rig and consult the specific tire's load chart.

Lug nut torque & pattern

Commercial truck wheels require serious clamping force. Proper torque is essential to prevent wheel-offs.

• Bolt Pattern: 10x285.75mm (Hub Piloted)
• Stud Size: M22 x 1.5
• Torque Specification: 450–500 lb-ft (610-680 Nm)
• Pattern: Always use a 10-lug crisscross (star) sequence.
• Note: Ensure the hub and wheel mating surfaces are free of rust and debris. Apply two drops of 30-weight oil to the stud threads and between the nut and the flange washer (do not lubricate the wheel face). Re-torque after 50-100 miles of driving following a wheel installation.

Common tire issues for this vehicle

1. Irregular Steer Tire Wear (Cupping/Rivering): The VNL's aerodynamic design puts significant weight on the steer axle. Improper toe settings, worn kingpins, or worn shocks will quickly cause steer tires to cup or develop "river" wear along the ribs.
2. Underinflation Blowouts on Inside Duals: Drivers often miss checking the inside dual drive tire. A flat or heavily underinflated inside dual will force the outside tire to carry double the load, inevitably leading to a catastrophic blowout on the highway.
3. TPMS Sensor Corrosion: Commercial truck TPMS sensors strapped inside the wheels can fail due to battery depletion or corrosion from moisture in the air lines. Ensure your air dryer is functioning correctly to keep moisture out of the tires.
