** Rim offset (ET) - distance from the mating plane of the disk to the middle of the rim.
If you need to drive onto a curb, you need to downshift and, if possible, return the wheels to the desired angle closer to the curb. Avoid vertical and sharp obstacles. While parking the vehicle, do not let the sidewall of the tire scrape.
Regularly inspect the tire surface for tread wear, foreign objects, and uneven wear. Uneven tire wear may indicate an uneven wheel alignment.
The wear depth of the tread is limited by relevant laws and regulations.
When the tread pattern is worn to a level where the indicator lugs are visible (2), the tires need to be replaced because the tread depth has decreased to 1.6 mm, resulting in poor grip on wet roads.
Worn tires must be disposed of in accordance with local environmental laws. As far as road conditions permit, winter tires should be replaced with summer tires immediately. This reduces fuel consumption and noise levels.
Change tires regularly. It is recommended to carry out such replacement of wheels each 10000 km. That is, change between the left front wheel to the right front wheel, and the right front wheel to the left rear wheel, (the maximum tire mileage is 50000-70000 km)
Tire replacement
The tires that are used on your vehicle are carefully selected to provide the best vehicle control, comfort and safety. The above tire and rim operating conditions apply to steel or aluminum alloy rims. If you would like to know about the use of other types of tires or rims on your vehicle, contact an authorized workshop.
The tire size of the vehicle affects the correct display of speed on the speedometer. If tire sizes (diameter) different from the original ones, the speedometer may display the wrong speed.
The use of improper tires and rims may result in an accident that is not covered by the warranty.
If you want to install non-standard tires or wheels, (such as alloy wheels or winter tires), follow the instructions or consult an authorized workshop.
It is recommended to check and adjust the wheel alignment of the vehicle during the first technical inspection, and then carry out a review and adjustment work every 10,000 km. (Costs are the responsibility of the consumer)
Anti-slip chains for snowy surfaces
Anti-skid chains for snowy surfaces can be used for both summer and winter tires, but only apply to the drive wheels (that is, the front).
When snow chains are used, the performance of a vehicle equipped with a monitoring system may have some anomalies in operation, which can be corrected by disabling this system.
In order to prevent damage to the full diameter wheel cover, it must be removed before installing the anti-skid chains.
The wheel cover is refitted as soon as the anti-slip chains have been removed.
When using chains, the vehicle speed must not exceed 50 km/h.
Chains must be removed immediately if there is no snow on the road.
How to choose discs
Immediately advice: if the car was bought on steel rims, it is better to put winter tires on them, and for summer, buy a beautiful «casting».
It is easier - but also more expensive - just to purchase original discs from an authorized dealer. If you want to save your hard earned money, use our tips.
Law is law
According to the traffic rules, the disks should not have cracks, visible violations of the shape and size of the mounting holes. So, you can buy any? Not quite, because there are still requirements of the automaker. They, of course, can be neglected, but then you run the risk of flying off the guarantee. After all, if problems arise with the chassis, you will have to prove that these are not the consequences of using non-standard disks (for example, with the wrong departure). Getting a diagnostic card honestly will not work, and meeting with an inspector on the road can lead to trouble.
Steel or light alloy
Wheels made of light alloys are divided into cast and forged. Forged wheels are stronger than cast wheels and are less prone to damage under heavy loads. But the harder the disk, the more the tire suffers on impact. Therefore, it is forged wheels that, when they hit the pit, pierce the sidewall of the tire.
Steel wheels are less aesthetic, but cheap and practical - a dented rim can be «roll» with virtually no loss of strength. Taking the impact energy on themselves, they treat the tires more carefully. For alloy wheels, repair is also possible, but the structure of the metal is violated, and therefore the restored disk is dangerous in operation.
1 - rim flange; 2 - shelf; 3 - hump; 4 - mounting plane; 5 (d) - landing diameter; 6 (b) - rim width; 7 (ET) - departure; 8 (PSD) - diameter of the circumference of the location of the fasteners; 9 (DIA) - diameter of the central hole for the hub; 10 - diameter of the adapter ring hole; 11- zone of possible contact between the spokes and the brake caliper; 12 - middle line; 13 - adapter ring
Look at the parameters
Permissible diameter and width of the disk can be found in the operating instructions for the car. The rest of the parameters will have to be looked for on the back of the native wheel. An alternative option is to use the selection of a disk for a car on specialized tire sites. The required dimensions are always available on the forums dedicated to this car model.
The diameter of the central hole should be commensurate with the diameter of the car hub - if the disc hole is slightly larger, you should purchase an adapter ring. It is necessary to take into account the diameter of the circle on which the bolts or wheel studs are located, and the number of holes for fasteners.
Step to the side
Larger diameter discs improve the appearance, handling of the car (when using low profile tires) and cooling brakes. But they are more expensive, as are the tires on them. And less practical: more likely to puncture the tire and lower driving comfort.
In addition, it is difficult to find steel wheels with a diameter of more than 16 inches. With standard tires, wheels wider than native should not be used. You will not get any advantages other than a spectacular appearance. But there is a high risk of damaging the disc when parking close to the curbstone. A tire mounted on a rim that is too wide does not work properly and wears out faster. And when cornering, the tire can touch the wheel arch.
Reducing the offset of the wheels widens the track of the car, and it becomes less rolled. But a short overhang overloads the wheel bearings and makes the steering response sharper when the wheel hits a bump.
There is another dimension - the distance from the brake caliper to the disc spokes. There were cases when, with all the observed parameters, non-native discs touched the brake mechanisms. Therefore, before installing tires, ask the tire fitters to try on the wheels on the car, and with new brake pads, when the caliper protrusion is maximum.
