Dimension designation for wheel rim
Wheel and rim dimensions are designated in accordance with the examples in the tablebelow.
All wheel rims have a dimension designation, for example: 8.5Jx19x47.5.
8.5 Rim width in inches
J Rim flange profile
19 Rim diameter in inches
47,5 Off-set in mm (distance from wheel centre to wheel contact surface against the hub)
The car has an approval for the complete vehicle with certain combinations of wheel rims andtyres.

Designations for tyre dimension, load index and speed rating.
The car has an approval for the complete vehicle with certain combinations of wheel rims andtyres.
Designation of dimensionsAll tyres have a dimension designation, such as:255/40 R19 100 W.
255 Tyre width (mm)
40 Ratio between tyre wall height and tyre width (%)
R Radial ply
19 Rim diameter in inches
100 Codes for the maximum permitted tyre load, tyre load index (LI)
W Speed rating for maximum permitted speed, speed rating (SS). (In this case 270 km/h (168 mph).)
Load indexEach tyre has a certain capacity to carry a load, a load index (LI). The car's weight determines theload capacity required of the tyres. The lowestpermitted load index is specified in a load indextable.
Speed ratingEach tyre can withstand a certain maximumspeed. Tyre speed rating, SS (Speed Symbol),must at least correspond with the car's topspeed. The table below shows the maximum per-mitted speed for each speed rating (SS). Theonly exception to these regulations is winter tyres3
, where a lower speed rating may be used.
If such a tyre is chosen, the car must not be driven faster than the speed rating of the tyre (forexample, class Q can be driven at a maximum of160 km/h (100 mph).) The top speed at whichthe car can be driven depends on road condi-tions, not the speed rating of the tyres.
NOTE
The maximum permitted speed is specified in the table.
Q 160 km/h (100 mph) (used only on win- ter tyres)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
W 270 km/h (168 mph) Y 300 km/h (186 mph)
3 Both those with metal studs and those without.

Weights Max. gross vehicle weight, etc. can be read on a label in the car.
Kerb weight includes the driver, the fuel tank 90% full and all fluids. The weight of passengers and accessories, and towball load (when a trailer is hitched) influencethe load capacity and are not included in the kerbweight. Permitted max. load = Gross vehicle weight - Kerb weight.
NOTE
The documented kerb weight applies to cars in the standard version - i.e. a car withoutextra equipment or accessories. This meansthat for every accessory added the loadingcapacity of the car is reduced correspondinglyby the weight of the accessory. Examples of accessories that reduce load capacity are the different equipment levels(e.g. Kinetic, Momentum, Summum), as wellas other accessories such as towbar, loadcarrier, space box, audio system, auxiliarylamps, GPS, fuel-driven heater, safety grille,carpets, cargo cover, power seats, etc. Weighing the car is a certain way of ascer- taining the kerb weight of your own particularcar.
WARNING
The car's driving characteristics change depending on how heavily it is loaded andhow the load is distributed.
The decal is positioned on the door pillar, and will be visible when the right-hand rear door is opened.
