Volkswagen Tiguan Service and Repair Manual: Rim Information

Overview - Rim

1. Rim Flange
   • Stop for the side tire bead
2. Hump (H2) on Both Bead Seats
   • Prevents the tire from slipping off the bead seat when driving around tight curves
   • An extended hump (EH2) is required when using run-flat tires.
3. Bed
   • Makes it easier to mount the tire

1. Rim Width
   • Distance between the tire contact surfaces on both rim flanges
   • Dimensions in inches
2. Rim Diameter
   • Distance between the rim contact surfaces on the opposite tire shoulders
   • Dimensions in inches
3. Offset
   • Distance between the vertical wheel center and the inner wheel contact surface
   • Dimensions in mm
4. Pitch Circle Diameter
   • Circle diameter where the wheel bolt holes are located
   • Dimensions in mm

Identification

There are several specifications located on the rim. The following examples shows the rim identification:

Replacement parts number:	6E0 601 027 A
Size of disc wheel:	6 J x 15 6 - Rim width in inches J - Shape of rim flange 15 - Rim diameter in inches
Offset (mm):	43
Indication for hump on bead seat:	EH2 Extended Hump 1)

¹) Raised round hump on both bead seats. These ensure that when using a tire with emergency mode properties in airless condition, the tire does not slip from the bead seat. Wheels with EH2 are only necessary if tires with emergency mode properties are mounted.

Composite Wheels

Composite wheels consist of various parts.

The primary components are rims and wheel discs. These components are fastened to each other with special screws and a special procedure. This ensures the wheel's function, proper seal, safety and true running. These important requirements cannot be guaranteed under shop conditions and using shop tools.

WARNING

Composite wheels must not be disassembled or repaired!

Light Alloy Wheels, Care and Maintenance

To maintain the decorative appearance of light alloy wheels for a long time, regular care is necessary.

In particular, road salt and dust from brake abrasion must be thoroughly washed off every two weeks. Otherwise, the paint of the light alloy wheel will be attacked.

Cleaning Agent

The following are appropriate cleaning agents:

• Water or water and soft soap
• Water and vinegar essence
• Light alloy wheel cleaning agents without acids or harsh solvents

Do not exceed the soaking time of the cleaning agent.

The shorter the specified soaking time is, the stronger and more aggressive the cleaning solution is.

Paint Damage

Fix paint damage as soon as possible.

Removing Adhesive Residue from Glued Balance Weights on Light Alloy Rims

• Harsh solvents and acids attack the paint on light alloy wheels and the surface of the wheel becomes matte and milky. These agents therefore must not be used.
• To remove adhesive residue on light alloy wheels, use light alloy cleansers or benzene-based cleanser. Do not exceed the soaking time of the cleaning agent.
• After cleaning or removing adhesive residue on the tires, they must be rinsed again with water.

Light Alloy Wheels, Preparing

WARNING

• Do not repair damaged rims by heating, welding or adding or removing material.
• Do not repair damaged or deformed rims or rims with cracked or deformed bolt holes.
• Only prepare wheels with tested and specified original paint materials.
• No warranty claims can be made against the manufacturer after preparing rims.

Do not repair rims that have cracks forming on the edges. Replace them immediately.

Cutting work, application of heat and welding applications of any kind are not permitted.

Reshaping material is not permitted.

The true running and axial run-out deviations before preparation must not exceed the manufacturing tolerance of 0.8 mm.

Only cast light alloy wheels may be primed. These wheels have the material identification AlSi xx on the inside.

Forged wheels may only be painted.

Preparation is limited to the painted surfaces.

Wheels that have been worn smooth that only have a clear coat may not be repaired.

Only surface damage on the visible side of the wheel may be prepared.

Damage must not be more than 1 mm deep.

Up to 50 mm of the rim flange may be removed and filled.

Valve, Removing and Installing

Valve, Removing and Installing, Valve Explanations

1. Valve Body

1. Valve body
2. Valve Insert
3. Valve cap

The rubber valve for tubeless tires is designed to seal air-tight in the hole in the rim. The elastic material of the rubber body presses itself tightly into the hole in the rim.

When valves with threaded metal feet are used, a rubber seal is used to seal the rim. The area around the edge of the valve hole is a sealing area. Therefore, they must be free of rust, dirt and damage.

2. Valve Insert

The valve core has the most important job in the valve. It creates a seal and enables the regulation of the air pressure. The small plate seal on the valve core can only do its job when it is free of impurities, dirt and moisture. The compressed air system must be free of water and oil!

3. Valve Cap

A valve cap must always be screwed onto the valves. It prevents dirt from getting into the valve. Dirt which may be in the valve would reach the seal of the valve plate when the tire is inflated and cause a leak.

The valve must be replaced every time a new tire is fitted.

If the vehicle is driven without caps on the valves, there is the danger that dirt may get into the valve. This leads to gradual loss of air and therefore lead to the destruction of the tire:

• Separation of carcass and rubber.
• Wide circumferential furrows in the area of the bead.
• Disintegrated tread or torn-out tread.

WARNING

An air-tight seal is ensured only if the valve cap is secured tightly.

Valve, Removing and Installing, Rubber Valve

Make sure wheel rim is clean.

• Using the Valve Fitting Tool Valve Fitting Tool -VAS6459--1-, insert a new tire valve.
• Remove the valve insert.
• Inflate tire to approximately 3 to 4 bar (43.5 to 58 psi), tire bead must slip audibly over rim hump when doing this.
• Install the valve insert.
• Check the tire pressure for specified pressure.
• Balance the tire.

Valve, Removing and Installing, Metal Valve

Special tools and workshop equipment required

• Torque Wrench -VAG1410-

Perform the Following:

Removing

• Remove the Tire Pressure Monitoring Sensor.
• Remove the nut -1- from the metal valve.
• Counterhold -arrow- the metal valve using a retainer (for example 2 mm spiral bore) while doing so.

Installing

Caution

Only apply the specified torque to tighten the nut for the metal valve. Tightening more is not permitted because it damages the seal.

• Tighten the nut -1- of the metal valve.
• Counterhold -arrow- the metal valve using a retainer (for example 2 mm spiral bore) while doing so.
• Install the Tire Pressure Monitoring Sensor.
