2010 VOLKSWAGEN TOUAREG wheel

For example, a tire graded 150 (Tread wear-value 150) would wear one-and-one-half (1 1/2) times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
Traction
The traction grades from highest to lowest, are AA, A, B and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor traction performance ⇒ .
Temperature
The temperature grades are A (the highest), B, and C representing the tire's resistance to the genera-tion of heat, and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of perfor-
mance on the laboratory test wheel than the minimum required by law ⇒ .
WARNING
The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning or peak traction characteristics.
WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.

Changing a wheel

WARNING
Changing a wheel, especially on the side of the road, can be dangerous. To help reduce the risk of serious personal injury:
x Always stop the vehicle as soon as it is safe to do so. Move the vehicle a safe distance off the road where it is safe to change the wheel.
x Always make sure that all passengers, especially children, are in a safe place outside the vehicle and away from the vehicle and traffic (such as behind a guard rail).
x Turn on the emergency flasher and set up another warning device about 25 yards (25 meters) behind the vehicle to warn approaching traffic.
x Change a wheel by yourself only if you are familiar with the necessary steps. Otherwise, get expert assistance.
x Always switch the engine off, firmly apply the parking brake, and shift the transmission into Park (P) (automatic transmission) or any gear (manual only) to help prevent the vehicle from moving suddenly and slipping off the jack.
x Always make sure that the ground is level and firm. If necessary, place the jack or a large and sturdy board or on a similar ground support.
x Always block the wheel diagonally opposite the wheel being changed with chocks or simi-lar things.
x If you are towing a trailer, always unhitch it from your vehicle before starting to change the wheel. Always apply the trailer brakes firmly and make sure the trailer cannot move unin-tentionally.
x Always use proper and undamaged tools when changing a tire.
x Once a wheel is lifted off the ground, having the transmission in Park (P) or in gear will not prevent sudden vehicle movement.
x Always use a jack that has been approved by the manufacturer for your vehicle. Never use other jacks, even if they have been approved for use on other Volkswagen models.
x To reduce the risk of losing control, crashes, and serious personal injuries, never loosen the screws on rims with threaded rim rings.
x After changing a wheel, have the wheel bolt tightening torque checked with an accurate torque wrench.
Preparations for changing a wheel

8. If the luggage compartment is loaded: Remove the luggage.
9. Take the collapsible spare tire and the vehicle tool kit out of the luggage compartment.
10. Take off the wheel bolt caps ⇒  Wheel trim.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common sense.
Wheel bolts

Fig. 337 Changing a wheel: Loosening wheel bolts.

Wheel bolt tightening torque
Correctly tightened bolts for steel and alloy wheel rims should have a torque of 133 ft-lbs. (180 Nm). After changing a wheel, have the wheel bolt tightening torque checked right away with an accurate torque wrench.
Before you check the tightening torque, replace corroded and difficult-to-turn wheel bolts and clean the threads in the wheel hub.
Never grease or oil the wheel bolts and the threads in the wheel hubs. The bolts can come loose while driving if greased or oiled, even if tightened to the required torque.
WARNING
Improperly tightened wheel bolts can come loose while driving and cause you to lose control over the vehicle, resulting in accidents and serious injuries.
x Only use wheel bolts that belong your vehicle and to the wheel being installed.
x Never use different wheel bolts.
x Wheel bolts and wheel hub threads must always be clean, easy-to-turn and free of oil and grease.
x Only use the lug wrench that is supplied with the vehicle to loosen the wheel bolts.
x Loosen the wheel bolts only about one turn before lifting the vehicle with the jack.
x Never grease or oil the wheel bolts and the threads in the wheel hubs. The bolts can come loose while driving if greased or oiled, even if tightened to the required torque.
x Never loosen bolted connections on wheel rims with bolted rim rings.
x If the wheel bolts are not tightened to the proper torque, the wheel can come off the vehi-cle when it is moving. Extremely high torque can damage the wheel bolts and/or their threads.
Lifting the vehicle with the vehicle jack

Fig. 338 Lift points for the jack.

2. Switch off the engine, shift the transmission into Park (P) ⇒  Shifting. Then apply the parking brake
to help prevent the vehicle from moving ⇒  Braking and parking.
3. If towing a trailer: Unhitch the trailer from the vehicle and park the trailer properly.
4. Straighten the steering wheel so that the front wheels point straight forward.
5. Block the diagonally opposite wheel with chocks or other suitable things.
6. Loosen the wheel bolts of the wheel to be changed ⇒  Wheel bolts.
7. Remove the scissors jack and tools from the vehicle.
8. Inset the extension ⇒ fig. 340 (A) into the scissors jack (B) Attach the crank (C) to the extension (A).
9. Find the jack lift point ⇒ fig. 340 on the vehicle frame that is closest to the wheel to be changed.
10. Crank up the jack so that it still just fits underneath the lift point.
11. Position the jack so that its base is directly underneath the lift point ⇒ fig. 341, making sure that the entire base of the jack rests securely on the ground.
12. Align the jack and wind up the jack claw at the same time, until the claw cradles the rib underneath
the vehicle ⇒ fig. 341 A or B.
13. Continue cranking up the jack until the wheel is just a little off the ground.
WARNING
Using the wrong jack to raise a vehicle with side steps, extended door sills, additional deco-rative trim or other enhancements in the area of the lower side sills can cause the vehicle to fall off the jack and result in serious personal injury.
x Never use the standard jack supplied with unmodified vehicles to raise the vehicle. The side step can interfere with the jack when raising the vehicle.
x Always use the scissor vehicle jack supplied with the authorized side step package when the vehicle must be jacked up, for example, to change a tire.
