1. Tire Pressure
For ordinary private car, the tire pressure is generally 2.4 to 3.0. Specific data on the door the owner can be found inside vehicle information, you can also search by vehicle or product specifications cover the tank. Riders need to be reminded to note that, generally speaking, the standard tire pressure front and rear wheels of the vehicle are not consistent. The tires lose air or whether it is enough play-off will lead to abnormal tire wear and shorten the life of the tire and increase vehicle fuel consumption, and even increase the chances of a puncture. Therefore, in addition to temporary holiday after inspection, the owner of the best tires to develop the habit of monthly check.
Tire balance is divided into two kinds of static equilibrium and homeostasis. Dynamic unbalance wheel will swing, so that it does not produce normal wear and tear; and static imbalance causes the vehicle to produce bumps and jumps. But after long-distance driving, the wheels are in balance volume change, so after the end of the holiday, as the wheels do dynamic and static balance check not only prolong tire life, but also improve the stability of the vehicle when driving and avoid driving the vehicle at a later date process, due to a tire swing, beating out of control and cause accidents.
The tire marks tire wear respective main drain tank, is a trapezoidal cross-section rubber bosses. When the tire tread wear and wear marks to flush, it means you must make the tires replaced. And if in the rainy season, in order to prevent the vehicle from skidding in the water surface, tire tread depth must be maintained at 3 mm or more.
Headlong into the hard tire easily include nails, screws, wire, glass fragments, sharp stones son, tiles, etc., and among these foreign bodies, nails and screws easiest tire punctured, causing the tire dark leakage, but also often stay in the tire breakage, not cleared up, it may exacerbate the degree of damage to the tire.
As long as careful observation of the riders will be able to check out the tires of the tire surface is hard objects stabbed. If a hard object tie to the site more subtle, ever tire surface watering riders also find bubbles coming out of the place, and sometimes even hear "hissing" sound discouraged.
5. along the sides and inside
Along the inner side of the tire and also the weak link. Some riders poor sense of place, often at the side of the tire rubs stop to curb the passage of time will wear side of the tire; tire damage along, it is due to operational errors at the hub disassembly tire caused This situation occurs in the basic installation of new tires or tire tire installation link.
Side of the tire damage can be directly observed it, and in severe cracking and drum kits. The inner edge is damaged, you will need to check the tire after the demolition, so the riders during disassembly tire repair shop, maintenance workers should carefully monitor the operation, when unusual circumstances, should be promptly stopped.
6. The gas nozzle
Gas mouth is when it detects tire riders most overlooked places. At present, private cars are basically equipped vacuum tire, gas nozzle mounted on wheels, its material is rubber. Rubber material of the gas nozzle in use for some time, due to the sun and rain and other natural erosion will gradually aging, texture gradually harden, eventually there will be cracks leak.
Check the gas nozzle, in addition to the surface to see if there is a crack, you can also touch the gas nozzle rubber, feel its softness. In addition, in order to prevent the gas nozzle aging caused by a flat tire, riders can purchase a couple of years for a tire replacement metal gas nozzle, avoid rubber aging occurs in the new car.
Automobile tires filled with air, the outer edge of the tire and wheel flange will fit closely to prevent gas leakage inside the tire. If the hub flange being collision deformation, it will affect their adaptation and the outer edge of the tire, causing the tire dark leakage.
The hub flange severely deformed, riders can be determined by visual inspection. However, if the hub flange deformation is not obvious, you need to remove the wheel inspection. To the joints of the tire and wheel watering, if bubbles are proof of the hub flange deformation, while bubbles of place, is the exact location of the deformation. If the riders found the hub there is a clear case of a crack or break, you need to immediately replace the new wheels. Even small cracks will become a hub fracture risk, its high degree of risk.
8. Shelf Life
Tire rubber shelf life is generally 4-5 years, the spare tire is the same, even if it has not been used once. A professional testing organization for different years of production and has not been used tires after an investigation found that the longer the tire is placed, its performance is worse. Therefore recommended that riders do not put the spare tire for a long time after use, and placed more than three years and do not buy tires.
Typically the production date will be marked on the outside of the tire sidewall, such as "1211" is the tire production date code indicates the tire is only the first 12 weeks of 2011 products.
Ordinary riders, the marking of the tire tire size parameters only concern. For example: 195/65 R15 93V, 195/65 is a flat ratio, R is a radial tire, the tire inner diameter of 15, 93, said load index, V represents the speed rating. Specific numerical load index and speed rating can query tables related content.
Many riders prefer when vehicle maintenance DIY, who intend to replace the tires if you will have to pay attention to the outside of the tires since the beginning, but once installed will make the use of anti-oriented drainage performance of the tire tread and grip performance greatly reduced. Usually printed on the outside of the tire "OUTSIDE" words or production date. Through one of these two identities, riders can determine that the outside of the tire
