Check your tire pressures regularly and always check before long journeys.
When driving, the tires warm up, therefore, the pressure check and tire inflation is carried out before the start of the trip or after the tires have cooled down after it.
The permissible tire pressure for each car is prescribed in the car's operating instructions, you can also find this information on the fuel filler flap of your car. Often the automaker indicates two values \u200b\u200b- for "normal" and "full" - the curb weight of the car (curb mass - mass car with standard equipment without cargo and passengers, but full refueling tanks). If one value is specified, then this value is for "normal" load, and the value for "full" load will be greater, by about 0.3-0.5 atm. The pressure for "full" load must be maintained for tires if they are wider than standard tires. For tires marked XL (Extra Load) (205/55 R16 98T XL) and RF (Reinforced) (205/55 R16 98T Reinforced), the pressure must be maintained above " full "load of 0.4 atm. In cases when you install tires with lower than those recommended by the manufacturer and in this case you need to increase the tire pressure by 0.1 atm. for each load unit (you have a recommended load of 107, and you put a tire with a load of 103, total (107-103) X0.1 \u003d 0.4 atm.)
If the pressure in the tires is lower than the permissible value, then the tread wear along the edge of the tire. When the tire is inflated, the tread wears off at the center of the tire. So, if your car has everything in order with the suspension, then failure to maintain the recommended tire pressure will lead to increased and uneven tread wear.
To overcome off-road conditions, you can lower the tire pressure while observing the minimum speed mode... The tire manufacturer claims that lowering the tire pressure from 2.5 to 1.0 bar increases the flotation by 30%, and decreasing the tire pressure from 1.0 to 0.5 bar increases the flotation by another 30%, but these tires are specially designed off-road.
If you have just purchased new BFGoodrich tires, then you should not overlook such an important factor as pressure. After installing the wheels on the car, it is imperative to check the pressure level; this can be done using a pressure gauge. But for some reason, many people miss this, but in vain. The pressure ensures safety while driving on the roads. It also helps to save gasoline, because at low tire pressure, fuel consumption increases, which can hit your pocket hard. In order to prevent this from happening, you need to constantly check and keep the pressure normal.
What affects the pressure level
ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!
Various factors can affect tire pressure in passenger cars. When inflating tires, you need to remember that each car model has its own pressure level, which is indicated in the operation of the car. In addition, it is worth considering other factors that affect the level of pressure:
What should be the pressure in BFGoodrich tires for passenger cars
The pressure level in BFGoodrich tires, as in other tire models, for passenger cars should vary between 1.9 and 2.2 atmospheres. In this case, it is imperative to take into account that the pressure level on one axis of the machine must be the same as the pressure on the other axis. On rear wheels usually 0.2 atmospheres higher than the front ones. But it is not desirable that the indicator be higher than the stated norms indicated on the tire.
Nevertheless, when determining the optimal degree of pressure, you need to focus primarily on the declared standards of the car manufacturer, and not on the tires.
How high blood pressure affects
If the tires are pumped, then this can lead to unpleasant consequences, namely:
It should also be borne in mind that with fast movement and maximum maneuverability, the degree of pressure in BFGoodrich tires increases by almost 0.5 atmospheres. And when long trips at increased speed it can increase by almost 4-5 atmospheres. And if the rubber has a cut or hernia, then it can overheat and explode right on the go, this can lead to a disaster.
Impact of low pressure on BFGoodrich tires
If the degree of pressure is less than 1.9 atmospheres, then this can lead to unpleasant consequences:
- When driving on flat tires, the rubber starts to wear off unevenly. As a result, the wheels become flat and their inclination level changes;
- May cause bending of the tire sides and rapid wear of this element;
- There is an increase in the area of \u200b\u200bcontact between the tire and the road, all this can cause excessive fuel consumption;
- Flat tires can get hot and explode the rubber as a result. All this can lead to a serious traffic accident;
- Sometimes the bead leaves the wheel. This leads to serious side damage.
Why there are different degrees of pressure
In frequent cases in different wheels the pressure level may be different. There are various reasons for this. Let's highlight the most basic ones:
- The spools are out of order;
- Uneven tire wear;
- It can also be due to the wheel hitting the nail.
It can also backfire. For example, for emergency braking the coefficient of adhesion to the road between inflated and flat wheels will be different. As a result, this can lead to a U-turn of the vehicle across the road.
Pressure level in winter and summer time
It must be remembered that seasonal changes affect tire pressure. temperature regime... Usually in summer time in extreme heat it rises. But in winter time in very coldy on the contrary, it goes down.
For example, if the temperature fluctuations reach 25 degrees Celsius, then the pressure level in the BFGoodrich tires will change as follows:
Features of checking and changing pressure in summer and winter period:
- In summer and winter, with strong jumps in temperature, the pressure level in the tires varies greatly. Therefore, during a sharp change in weather and season, it is necessary to constantly measure the pressure parameters;
- In winter, it is best to pump up two hours after stopping the transport. It is advisable during this period to adhere to the standards established by the car manufacturer;
- If in winter time the pumping is done in a garage or in any covered room where the air temperature is at least + 5 degrees Celsius, then it is better to increase the rate by 0.2 bar. This will compensate for temperature differences so that the tires on the street will have the correct pressure level.
Also, in cold weather, the cause of unstable or low level pressure can also be caused by other reasons - nipple, rubber tubeless valve, rubber wear and loss of elasticity, and air mixture can also affect. In these cases, you can use the service - inflation of tires with liquid nitrogen. Liquid nitrogen is not affected by temperature fluctuations and can maintain an optimal pressure level for a long time.
SUV tire pressure
SUVs are often used for driving both on difficult trails and for driving on urban road surfaces... Mandatory for safe driving need to install quality tires... For SUVs the best option are the wheels of Goodrich Mud Terran.
They have good technical characteristics - high permeability, adhesion to slippery and wet surfaces, repelling dirt, moisture and dust. In addition, in order to ensure safety while driving, it is imperative to control the pressure level. The wear of the rubber, the passability and the quality of the movement of the machine depend on it.
Pressure test rules
SUV tires are always in constant contact with the road, so their condition is the main component of the safety of the driver and passengers. This element of the car is the most vulnerable part, and in need of constant checking. Special great attention must be given to pressure. In jeeps and SUVs, it should be between 2.2 and 2.5 atmospheres.
In order for Goodrich mud tires to retain their qualities for a long time and serve for a long time, the following recommendations should be followed:
BFGoodrich Tire Pressure Measurements
In order to find out accurate pressure measurements, a special device should be used. Usually a pressure gauge is used for these purposes. Pressure gauges are of different types:
- Arrow type. These devices are based on a manometric spring;
- Mechanical type, based on a coil spring;
- Electronic type. These are more modern devices, they come with a special electronic screen, which displays all the data.
A dial gauge is often used. It has high precision and low cost. However, it has a drawback - fragility. When falls, hits, mechanical stress and physical interventions, the manometric spring, which is installed inside the device, fails. As a result, the values \u200b\u200bmay not be accurate.
The mechanical pressure gauge is a reliable instrument, it is not afraid of shocks, falls and other mechanical influences. However, it has a very significant drawback, the test results may be inaccurate.
The most accurate is an electronic pressure gauge, its results may deviate by minimum values only ± 0.05 Bar (Atmospheres). But it has a very high cost.
How to measure pressure correctly
In order for BFGoodricn tires to always be in good condition, it is imperative to periodically check its pressure. To facilitate this process, it is advisable to follow the following tips:
Remember that visual inspection "by eye" is self-deception, so do not trust the look of the tires. Especially if you are not experienced driver... This often leads to serious consequences. It is best to protect yourself and periodically do checks with a pressure gauge, and be sure to check four tires at once.
BFGoodrich tires, like the wheels of other manufacturers, require proper care. Be sure to monitor the level of pressure in the tires, because the wear and quality of rubber depends on it. It also provides a comfortable ride, high safety and gas mileage. The main thing is to observe the optimal pressure and check it periodically, then you can avoid many unpleasant consequences.
The American company BFGoodrich has been producing car tires since 1910. The name of the company comes from the name of the legendary pioneer of American industry - Dr. Benjamin Franklin Goodrich (years of life: November 4, 1841 - August 3, 1888). He is the creator of the first tires in the United States. He founded the BFGoodrich Campaign in 1870 in Akron, Ohio.
It was BFGoodrich who manufactured the tires for the first US-sold Winton. This made the brand a leader in the American tire industry. This moment is considered the starting point of the long history of the BFGoodrich brand.
In 1927, Charles Lindbergh made the world's first non-stop flight across the Atlantic. The wheels of his plane “The Spirit of St. Louis ”wearing BFGoodrich tires.
Nearly 20 years later, in 1945, BFGoodrich began producing synthetic rubber tires.
In 1965, BFGoodrich produced the world's first radial tire.
Since 1986, BFGoodrich has been a division of Uniroyal, and after the acquisition of Uniroyal by Michelin in 1990, it became a division of Michelin.
One of the brightest specializations of the company is the production of tires for extreme operating conditions.
The BFGoodrich tire range contains both business class tires for everyday use, as well as sports and tuning tires for passenger cars and SUVs. The M / T class off-road tires with an aggressive tread pattern for driving in the desert and off-road enjoy a well-deserved reputation.
BFGoodrich tires are always of high quality and good performance.
The company has always been distinguished reasonable prices with unchanged high quality and product innovation.
BFGoodrich All-Terrain - 50% ROAD, 50% OFF ROAD
Technologies:
1. Aggressive tread pattern for confident flotation.
A pronounced tread pattern with more sipes and wider shoulder grooves improves traction on all surfaces. To improve the cross-country characteristics, the "Shoulder Lock" technology is used: the tread pattern extended to the sidewall and widened shoulder grooves.
2. Reinforced frame for greater strength and flotation.
The Trigard system (3-ply frame) and two metal breaker layers provide increased resistance to external influences: impacts, punctures and cuts. The tire bead design provides rim protection.
3. The special design of the tire allows it to move at very low pressure.
On a BFGoodrich All-Terrain tire, it is possible to reduce the pressure down to 0.5 bar. Lowering the pressure improves cross-country ability in difficult soft off-road conditions (sand, swamp, loose soil).
BFGoodrich Mud-Terrain T / A KM2 - 20% ROAD, 80% OFF ROAD
Technologies:
1. Rubber compound, resistant to aggressive environment.
Composition rubber compound improves protection against tears and cuts possible when driving on rocky, gravel and other surfaces.
2. Aggressive shoulder lugs for better flotation.
Massive lugs not only increase flotation, which is especially important at low tire pressure, but also, due to their displacement to the tire sidewall, provide additional protection from damage in the most extreme off-road conditions.
3. Cord threads aimed at strengthening the strength.
Increased code threads by 33% (compared to previous model) Trigard systems (3-ply carcass) protect the carcass when driving off-road.
4. The special design of the tire allows driving at very low pressure.
On the BFGoodrich Mud-Terrain tire it is possible to reduce the pressure down to 0.5 bar. Lowering the pressure improves cross-country ability in difficult soft off-road conditions (sand, swamp, loose soil).
Example of operation on sand:
Lowering the pressure from 2.5 to 1 bar increases the permeability by 30%.
Decreasing the pressure from 1.0 bar to 0.5 bar increases the permeability by 30%.
The pressure reduction can only be used at very low speeds and over short distances. After overcoming the special stage, the tire pressure must be restored.
