2021 Ford Transit — Tire Size & Pressure

Quick answer

• OEM Tire Size: 235/65R16C
• Recommended Cold Tire Pressure (door placard): Varies by configuration and GVWR, typically 51-71 PSI front, 51-74 PSI rear.
• Bolt Pattern: 6x130mm
• Wheel Size: 16x6.5J (steel or aluminum)
• Load Index/Speed Rating: 121/120R (Load Range E)
• Spare Tire Size: 235/65R16C
• TPMS Frequency: 315 MHz

Tire sizes by trim

The 2021 Ford Transit (cargo van, passenger van, and cutaway chassis) primarily utilizes one tire size across most configurations, with variations in load capacity due to different Gross Vehicle Weight Ratings (GVWRs).

Note: Always consult your specific vehicle's doorjamb placard for the precise recommended tire pressures, as these can vary based on your van's configuration, wheelbase, roof height, and GVWR.

Recommended replacement tires

When replacing tires on your 2021 Ford Transit, it's crucial to select tires that meet or exceed the original equipment's load index and speed rating, especially given the vehicle's intended use for carrying heavy loads. Commercial (C) rated tires are essential.

• Michelin Agilis CrossClimate (Premium Tier)
  • Known for excellent all-weather traction, durability, and a long tread life. A popular choice for commercial vehicles needing reliable performance in various conditions.
• Continental VanContact A/S (Mid-Premium Tier)
  • Offers a good balance of all-season capability, comfortable ride, and robust construction suitable for heavy-duty applications.
• Goodyear Endurance RSA (Mid Tier)
  • A reliable option for those seeking a durable, long-lasting tire designed for commercial use, offering good traction and stability.
• Firestone Transforce HT2 (Value Tier)
  • A solid choice for commercial light trucks and vans, providing good highway performance, durability, and strong hauling capabilities.

When to inflate to max load psi

Heavy-duty vehicles like the Ford Transit often have tire pressure recommendations that change based on the load carried. For your 2021 Ford Transit, you should inflate your tires to the maximum recommended PSI for a full load only when your vehicle is consistently operating at or near its maximum Gross Vehicle Weight Rating (GVWR) or Gross Axle Weight Rating (GAWR).

• Always refer to your doorjamb sticker: This placard provides the specific cold inflation pressures for both light and full load conditions.
• Under-inflation with heavy loads: Can lead to excessive heat buildup, premature tire wear, reduced fuel efficiency, and a higher risk of tire failure.
• Over-inflation with light loads: While not as immediately dangerous as under-inflation, over-inflating for light loads can result in a harsher ride, uneven tire wear (center wear), and potentially reduced traction.

For daily driving with varying loads, it's best to adjust the tire pressure according to the load you are carrying, using the placard as your guide. If you frequently carry heavy loads, maintaining the higher pressure listed for maximum load can be beneficial.

Lug nut torque & pattern

Lug Nut Torque: Ensure all lug nuts are tightened to 150 lb-ft (204 Nm). Always use a calibrated torque wrench for accuracy. Improper torque can lead to wheels coming loose or damaged studs/wheels.

Lug Nut Pattern: The 2021 Ford Transit uses a 6-lug (6x130mm) bolt pattern. When re-installing wheels, tighten the lug nuts in a star or criss-cross pattern. This ensures even seating of the wheel against the hub and prevents warping of the brake rotor or wheel.

Common tire issues for this vehicle

• Rapid or Uneven Tread Wear: Due to the heavy nature of the Transit and its potential for high loads, maintaining correct tire pressure is paramount. Incorrect alignment, worn suspension components, or consistent overloading can also accelerate wear, especially on the front tires.
• Load-Related Failures: Using passenger (P-metric) tires instead of the required commercial (C-rated or LT-metric) tires or operating with under-inflated tires while heavily loaded can lead to blowouts or rapid tire degradation.
• TPMS Malfunctions: While generally reliable, TPMS sensors can occasionally fail or give inaccurate readings. This is often due to battery depletion (after many years) or damage during tire changes. Ensure sensors are properly handled during tire service and recalibrated if necessary.
• Vibration Issues: Unbalanced tires, bent wheels, or worn steering/suspension components can cause vibrations, which are often more noticeable in larger, heavier vans. Regular tire rotations and balancing are recommended to prevent these issues.
