2022 Volvo VNR — Tire Size, Pressure, Bolt Pattern & Wheel Specs

Quick answer

• OEM tire size: Common factory fitments are 11R22.5 (steer/drive duals) or 295/75R22.5. Optional: 11R24.5, steer wide-base 385/65R22.5, and drive wide-base singles 445/50R22.5 or 455/55R22.5.
• Recommended cold tire pressure (door placard): Steer 105–120 psi; drive duals 90–110 psi; wide-base singles 100–120 psi. Follow the specific pressures on your VNR’s driver-door/door-frame placard tied to GAWR and tire size/load range.
• Bolt pattern: 10x285.75 mm, hub‑piloted (M22x1.5 studs; two-piece flange nuts).
• Wheel size/offset: Most common 22.5x8.25 dual-position. Options: 24.5x8.25; steer wide-base on 22.5x12.25; drive wide-base on 22.5x14. Uses standard hub‑piloted offsets for dual or single positions—verify inset/outset stamped on the wheel.
• Load index/speed rating: Typical examples—11R22.5 LRH ~146/143 L; 295/75R22.5 LRG/H ~144/141 L; 11R24.5 LRH ~149/146 L. Speed “L” (75 mph) is common; always match the tire’s single/dual load indices to axle GAWR.
• Spare tire: Class 8 tractors are not factory-equipped with a spare.
• TPMS frequency: Varies by supplier; 433 MHz is common on heavy‑truck TPMS, though some aftermarket kits use 315 MHz. Confirm by sensor part number or service info.

Tire sizes by trim

These are typical 2022 VNR regional-haul fitments; always confirm your VIN/placard.

Recommended replacement tires

Price ranges vary by market; rough street pricing per tire shown for 22.5-inch sizes.

• Premium long-wear/fuel: Michelin X Line Energy Z (steer) / D (drive) or X Multi Z/D for regional ($650–$850). Excellent fuel economy and irregular-wear resistance.
• Premium regional: Bridgestone R268 Ecopia (steer) / M710 Ecopia (drive) ($600–$800). Strong for stop‑and‑go and curb scuff.
• Mid-tier value: Continental Conti EcoRegional HS3/HD3 or HSR2/HDR2+ ($500–$700). Balanced cost and mileage.
• Mid-tier/wide-base: Goodyear Fuel Max RTD (drive singles) / G296 MSA/ Endurance RSA (steer) ($500–$750).
• Budget/fleet: Yokohama 104ZR (steer) / 902L (drive) or similar ($400–$600). Reliable with good casing retreadability.

Match load range (usually G or H on 22.5s) and single/dual load index to the axle GAWR on your placard. If you run wide‑base singles, ensure axle/ratio approvals and correct wheel width (typically 22.5x14).

When to inflate to max load psi (HD trucks)

Use the sidewall “Max Load at X psi cold” only when you are at or near the axle’s GAWR and the tire maker’s load table requires it. Examples:

• Steer axle near 12,000–13,200 lb with LRH 11R22.5 may need 110–120 psi.
• Tandem drive near 34,000 lb with duals often runs 95–105 psi depending on size and load range.
• Wide‑base singles at high axle loads often call for 110–120 psi.

For everyday regional work with variable loads, set cold pressures from the tire manufacturer’s load/inflation tables for your actual axle weights—never below the door‑placard spec. Check cold, before sunrise heat/operation, and use metal valve caps/extendors rated for HD service.

Lug nut torque & pattern

• Pattern: 10x285.75 mm, hub‑piloted with M22x1.5 studs and two‑piece flange nuts (do not mix with older stud‑piloted hardware).
• Torque: 450–500 lb‑ft (610–680 N·m) on clean, dry studs/nuts unless Volvo/wheel maker specifies otherwise. Re‑torque after 50–100 miles following wheel service.
• Tighten in a star/alternating pattern. Never lubricate cone seats; only lightly oil under‑nut flange if specified by wheel maker.

Common tire issues for this vehicle

• Steer “river wear”/cupping: Often alignment (toe), kingpin/bushing wear, or low inflation. Rotate side‑to‑side at 20–25k as needed and keep steer at placard psi.
• Drive heel‑and‑toe: Caused by torque and low pressure; maintain correct psi and consider deeper‑tread regional drive designs.
• Inner shoulder wear on duals: Usually under‑inflation or axle misalignment—use calibrated gauges and periodic axle measurements.
• Wide‑base singles edge scrub: Sensitive to pressure and axle alignment; weigh axles and set psi to load tables.
• Valve/extension leaks and galvanic corrosion at wheel seats: Inspect stems/TPMS every service; use approved flange nuts and correct hub‑piloted wheels.
