Important safety notes

WARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components may be damaged. There is arisk of an accident.
Always replace wheels and tires with those that fulfill the specifications of the original part.
When replacing wheels, make sure to use the correct:

• designation
• model
  When replacing tires, make sure to use the correct:
• designation
• manufacturer
• model

Aflat tire severely impairs the driving, steering and braking characteristics of the vehicle. There is a risk of accident.
Tires without run-flat characteristics:
do not drive with aflat tire. Immediately replace the flat tire with your emergency spare wheel or spare wheel, or consult a qualified specialist workshop.
Tires with run-flat characteristics:
pay attention to the information and warning notices on MOExtended tires (tires with run-flat characteristics).

Accessories that are not approved for your vehicle by Mercedes-Benzorare not being used correctly can impair the operating safety.
Before purchasing and using non-approved accessories, visit a qualified specialist workshop and ask about:

• suitability
• legal stipulations
• factory recommendations
  Information on the dimensions and types of wheels and tires for your vehicle can be found in the “Wheel/tire combinations” section (Y page 372).
  Information on air pressure for the tires on your vehicle can be found:
  Ron the vehicle’s Tire and Loading
  Information placard on the B-pillar (Y page 355)
• on the tire pressure label on the fuel filler flap (Y page 180)
• under “Tire pressure” (Y page 348)

Information on driving
If the vehicle is heavily loaded, checkthe tire pressures and correct them if necessary.
While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tires are damaged. If you suspect that a tire is defective, reduce your speed immediately. Stop the vehicle as soon as possible to check the wheels and tires for damage. Hidden tire damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tires and wheels checked at a qualified specialist workshop.
When parking your vehicle, make sure that the tires do notget deformed by the curb or other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, may be damaged.

Regular checking of wheels and tires 

WARNING
Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tires regularly for signs of damage and replace any damaged tires immediately.

Regularly checkthe wheels and tires of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tire pressure. Pay particular attention to damage such as:

• cuts in the tires
• punctures
• tears in the tires
• bulges on tires
• deformation or severe corrosion on wheels
• egularly check the tire tread depth and the condition of the tread across the whole width of the tire (Y page 345). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface.
  All wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure monitoring systems. Regularly check the pressure of all the tires particularly prior to long trips. Adjust the tire pressure as necessary (page 348).
  Observe the notes on the emergency spare wheel (page 377).
  The service life of tires depends, among other things, on the following factors:
• driving style
• tire pressure
• distance covered

Important safety notes on the tire tread

WARNING
Insufficient tire tread will reduce tire traction. The tire is no longer able to dissipate water. This means that on wet road surfaces, the risk of hydroplaning increases, in particular where speed is not adapted to suit the driving conditions. There is a risk of accident.
If the tire pressure is too high or too low, tires may exhibit different levels of wear at different locations on the tire tread. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires.
Minimum tire tread depth for:

• Summer tires: â in (3 mm)
• M+S tires: ã in (4 mm)
  For safety reasons, replace the tires before the legally prescribed limit for the minimum tire tread depth is reached.

Bar indicator : for tread wear is integrated into the tire tread.
Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They are visible once a tread depth of approximately á in (1.6 mm) has been reached.Ifthis is the case, the tire is so worn that it must be replaced.

Selecting, mounting and replacing tires

• ROnly mount tires and wheels of the same type and make.
  Exception: it is permissible to install a different type or make in the event of a flat tire. Observe the “MOExtended tires (tires with run-flat characteristics” section (Y page 329).
• Only mount tires of the correct size onto the wheels.
• Break in new tires at moderate speeds for the first 60 miles (100 km). They only reach their full performance after this distance.
• Do not drive with tires which have too little tread depth, as this significantly reduces the traction on wet roads (hydroplaning).
• Replace the tires after six years at the latest, regardless of wear.
  Observe the notes on the emergency spare wheel (Y page 377).

Uniform Tire Quality Grading Standards
Overview of Tire Quality Grading Standards
Uniform Tire Quality Grading Standards are U.S. government specifications. Their purpose is to provide drivers with uniform reliable information on tire performance data. Tire manufacturers have to grade tires using three performance factors 1 tread wear grade, 2 traction grade and 3  temperature grade. These regulations do not apply to Canada. Nevertheless, all tires sold in North America are provided with the corresponding quality grading markings on the sidewall of the tire.
Where applicable, the tire grading information can be found on the tire sidewall between the tread shoulder and maximum tire width.

Example:

• Treadwear grade: 200
• Traction grade: AA
• Temperature grade: A
  All passenger car tires must conform to the statutory safety requirements in addition to these grades.
  The actual values for tires are vehicle specific and may deviate from the values in the illustration.

Treadwear
The treadwear grade is a comparative rating based on the wearrate of the tire when tested under controlled conditions on a specified U.S. government course. For example, a tire graded 150 would wear one and one-half 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 conditions.

Traction
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.
Avoid wheelspin. This can lead to damage to the drive train.
The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on a wet surface as measured under controlled conditions on specified government test surfaces of asphalt and concrete. Atire marked C may have poor traction performance.

The safe speed on a wet, snow covered or icy road is always lower than on dry road surfaces.
You should pay special attention to road conditions when temperatures are around freezing point.
Mercedes-Benz recommends a minimum tread depth of ã in (4 mm) on all four winter tires. Observe the legally required minimum tire tread depth (Y page 345). Winter tires can reduce the braking distance on snow-covered surfaces in comparison with summer tires. The braking distance is still much further than on surfaces that are not icy or covered with snow. Take appropriate care when driving.
Further information on winter tires (M+S tires) (Y page 346).

Temperature 
The temperature grades are A(the highest), B, and C. These represent the tire’s resistance to the generation 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 Ccorresponds 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 performance on the laboratory test wheel than the minimum required by law.
