Loading Information
Definitions
The rear-axle load is the vehicle weight on the rear axle plus the weight of the transported load.
The Curb weight – actual weight of your vehicle - vehicle weight including standard and optional equipment, fluids, and emergency tools. This weight does not include passengers and cargo.
The Gross Vehicle Weight is the sum of the curb weight and the weight of passengers and cargo combined.
The Gross Vehicle Weight Rating is the maximum total weight of vehicle, passengers, luggage and optional equipment.
The Gross Axle Weight Rating is the maximum load limit for the front or the rear axle. This information is located on the safety compliance sticker located in the driver’s side door aperture area.
For determining the compatibility of the tire and vehicle load capabilities:fPlease see the chapter “TIRES AND WHEELS” on page 244.
The load capacity coefficient (e.g. “106”) is a minimum requirement. For more information:fPlease see the chapter “INSCRIPTION ON RADIAL TIRE” on page 252.
The Gross Combined Weight Rating is the maximum total weight rating of vehicle, passengers and cargo.
The Vehicle Capacity Weight – Load Limit - is the maximum total weight limit specified of the load (passengers and cargo) for the vehicle. This is the maximum weight of passengers and cargo that can be loaded into the vehicle. This infor-mation can be found on the tire pressure plate.
The maximum loaded vehicle weight is the sum of curb weight, accessory weight, vehicle capacity weight and production options weight.
The load rating is the maximum load that a tire is rated to carry for a given inflation pressure.
The maximum load rating is the load rating for a tire at the maximum permissible inflation pressure.
The cargo capacity is the permissible weight of cargo, the subtracted weight of passengers from the load limit.fNever exceed the permissible limits.
Injuries are much more likely in an accident if persons ride in the cargo area.fPersons must ride only on the seats provided for this purpose. fMake sure that everybody fastens their safety belts.
Overloading will lead to dangerous vehicle reactions and long braking distances.fNever exceed the specified axle loads.
Risk of damage to the vehicle if the vehicle is overloaded.
Overloading can shorten the service life of the tires and car. Damage due to overloading is not covered by the vehicle warranty.fNever exceed the specified axle loads.

Example for determining the combined weight of occupants and cargo
Vehicle Load Capacity
fThe combined weight of occupants and cargo should never exceed the weight shown on the tire plate in the vehicle.Please see the chapter “TIRE PRESSURE PLATE” on page 284.fNever exceed the number of passengers shown on the tire pressure plate in the vehicle.
Determining the combined weight of occupants and cargo:
fAdd the weight of all occupants and then add the total luggage weight ( figure).
Steps for determining correct load limit
1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX pounds” on your vehicle’s placard (depending on the date of manufacture).2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds.4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs. and there will be four - 150 lb passengers
in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. [1400 - 600 (4 x 150) = 800 lbs.]. 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

Risk of damage to the vehicle and to the tires.
Damage due to overloading is not covered by the vehicle warranty.
Tire damage may also be caused by overloading, and this damage is not covered by your tire warranty.fDo not overload your vehicle. Be careful about the roof load. fIf you plan to load the vehicle, first correct the tire pressure. Tire pressure for loaded vehicle can be found on the tire pressure plate and in the chapter technical data.fNever exceed the specified axle load.
fPlease see the chapter “LOADING INFORMATION” on page 204.

A Seating capacity
Maximum number of vehicle occupants, including the driver.B Vehicle load limit
Is the maximum total weight limit specified of the load (passengers and cargo) for the vehicle. This is the maximum weight of passengers and cargo that can be loaded into the vehicle. Please see the chapter “LOADING INFORMATION” on page 204.
C Original tire size
Size of tires mounted at the factory. D Recommended cold tire inflation pressure
These values are for cold tires (68 °F/20 °C).
Tire traction
When driving on wet or slushy roads, a wedge of water may build up between the tires and the road. This phenomenon is known as “hydroplane” and may cause partial or complete loss of traction, vehicle control or stopping ability.fReduce speed on wet surfaces.

The standard tires profile and rubber mixture are optimized for wet and dry driving conditions, and may not prove favorable for snow conditions.fInstall snow tires before driving in such conditions.
Risk of insufficient road grip leading to loss of control and damage to the vehicle.
The standard tires profile and rubber mixture are optimized for wet and dry driving conditions, and may not prove favorable for snow conditions.fInstall snow tires before driving in such conditions.
Before mounting snow tires, consult with your Porsche dealer. They have the technical information necessary to advise you on wheel and tire compatibility.fSnow tires should have the same load capacity as original equipment tires and should be mounted on all four wheels.
Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases the rate of wear of the affected tires and causes damage.
Tires with badly worn treads are very dangerous and could cause accidents.fMake sure they are replaced immediately.fDo not exceed the snow tire speed rating.
Snow tires do not have the same degree of traction on dry, wet or snowfree roads as normal tires. Furthermore, snow tires wear rapidly under these conditions.
Information
We recommend that you fit snow tires on the vehicle at temperatures below 45 °F (7 °C) since the driving performance of summer tires is reduced at low temperatures and a lower level of comfort can also be expected. For example, juddering noises caused by the tires can occur while maneuvering the vehicle or accelerating out of bends on both dry and wet road surfaces.Extremely low temperatures of below 5 °F (-15 °C) can cause permanent damage to summer tires.
Snow tires lose their suitability when their tread depth falls below 5/32 in. (4 mm).
Comply with all state and local laws governing snow tire and tread depth requirements.
Exceeding the maximum permitted speed for the tires fitted could cause tire failure.fAlways check the maximum speed rating on the tire sidewall on any tire on the vehicle.fNever exceed the maximum speed rating of the tires.
Wheel change
fWhen wheels are removed, mark the direction of rotation and position of each wheel.Example: FR (front right), FL, RR and RL.fAlways fit the wheels in accordance with the markings.
Snow chains
Risk of damage to body, axle or brake components.fFit snow chains only to the rear wheels, and only with the tire/rim combination listed in the Technical Data.fUse only the fine-link snow chains recommended and authorized by Porsche so that sufficient clearance between the wheel well and the chain is assured.fPlease see the chapter “WHEELS, TIRES” on page 286.fFollow instructions issued by the supplier of the chains.

Fitting snow chains
fBefore fitting chains, remove accumulated ice and snow from the wheel well.fVehicles with snow chains must not be driven faster than 30 mph (50 km/h).
Different states and countries have varying statutory requirements regarding maximum speed.fCheck with local authorities for possible restrictions.fRemove chains as soon as the roads are free of ice and snow.

fApproval of tire and wheel sizes is granted based on extensive testing. By fitting tires that have been approved by Porsche, you can be sure that you have the best possible tires for your Porsche.The load capacity coefficient (e.g. “91”) and maximum speed code letter (e.g. “Y”) for permitted top speed are minimum requirements. When fitting new tires or changing tires: Please see the chapter “TIRES AND WHEELS” on page 244.fSnow chain clearance can only be guaranteed with the tires marked 1). Snow chains can only be fitted on the rear wheels. Observe state or province-specific laws regarding maximum speeds with fitted snow chains.
