For the Bentley Bentayga (2016–Present), the “4V1” designation typically refers to the 22″ 5-Spoke Directional Wheel set. These wheels are a signature element of the Mulliner Driving Specification and are highly sought after for their aggressive, turbine-like aesthetic.

1. Technical Specifications

Because these wheels are directional, the set is comprised of two distinct part numbers (two for the left side and two for the right side) to ensure the spokes “twist” in the same direction on both sides of the vehicle.

2. Common Part Numbers & Finishes

The finish of the wheel determines the specific part number suffix. The most common versions for the 4V1 design are:

• Black & Machined (Diamond Cut): * Left: 36A601025KU (or 36A601025AP)

  • Right: 36A601025JU (or 36A601025AN)

• Bright Silver:

  • Left: 36A601025AD

  • Right: 36A601025AE

• Gloss Black: Often found under the Blackline Specification (Part numbers vary by year, often ending in S or BT).

3. Buying & Installation Tips

• Directional Orientation: When purchasing a used set, verify you have two lefts and two rights. Using four identical wheels will result in the design “slanting” forward on one side of the car and backward on the other.

• TPMS Sensors: Ensure the set includes the 433MHz TPMS sensors. If moving from 21″ wheels to 22″, you will need to update the tire pressure settings in the infotainment “Car” menu to avoid dashboard errors.

• Center Caps: These wheels typically use the “Self-Leveling” Mulliner wheel badges (3W0601170C), which remain upright while the wheel rotates.

• Weight Note: These are heavy, high-load-rated alloy wheels. Ensure any aftermarket or refurbished units are not cracked or “re-welded,” as the Bentayga’s weight puts immense stress on the rim structure.
