Q:Which brand has the best car tires?

When Michelin F1 sponsors, it is the leader and Bridgestone tires, is second, now Bridgestone is a sponsor of the F1, of course, it also became a tire leader, Michelin ranked second (ranked from the top five hundred in the world can be seen), when it comes to super car tire brand, of course is the best Pirelli like Lamborghini, Ferrari, Porsche, BMW, Mercedes Benz, and some other sports car are made of pirelli. The following content you can refer to: ten famous tire brand rankings, strengths and weaknesses detailed explanation, big PK

Q:The side of the car is leaking in the side. Is it dangerous to mend it?

Because the side of the tire is relatively weak, if it is a side scratch, almost impossible to repair, such as continued use, there is a risk of a tire blowout, there are security risks.

Q:Hydrogen can on truck tires inside ah, if it can charge a truck wagon not light, Dora goods

The problem of how hydrogen has been used as a source of energy has not been resolved

Q:How tight is the screw for the car tires?

The compressed air pressure of 4 ATM, the use of wind gun when the torque value tighten around 40-50N.m, you'd better choose a bolt or nut, use your common air gun made in the use of the boosting rod tighten with the normal force, to check how much torque, so there is a number in the heart. By the way, your boss say a bolt or nut screwed on the ground is not too tight, any thread needs a proper preload, ensure the thread can lock the screw thread but not too loose, easy to cause the thread off, easily lead to tooth fracture or too tight. The car wheel fixing screw torque should be much, car maintenance manual should be clearly defined, I haven't checked, can not talk, suggest you check the vehicle maintenance manual, with practice, must be able to grasp. In addition, the order of the wheel screws should be played diagonally, not one by one in sequence.

Q:Are there any standards for car tyre change?

Experts suggest that the tyres must be used when the tires are worn to the limit, i.e., when the tread tread is less than 1.6 millimeters deep. Tires that are aged or deformed or even damaged by tire rings should be stopped immediately. So, if your tires have the above case, so it's enough to replace the standard tire, hoping to immediately replace the partial grinding or severe wear of the tires, to ensure their own safety and that of others.

Q:Automobile tyre symbols

Cord tire alone: some signs, such as "nylon" (NYLON), the general standard in the world level; some tire manufacturers marked in the specification, expressed by the first letter of Chinese phonetic alphabet, such as 9 20N, 7.50 20G, N said, G said, M nylon wire, Cotton Table R said rayon.Load and air pressure: generally indicate the maximum load and the corresponding air pressure, the load is "kg", the tire pressure is the tire pressure, and the unit is "kPa"".Rim specification: Specifications for rims used to match tyres. For practical use, such as "standard rims", 5.00F".Balance mark: made of colored rubber, marked shape, printed on the tire side, which means that the tire here is the lightest, the assembly should be facing the valve to ensure the balance of the entire tire.

Q:After the first four, the eight van was replaced with a vacuum tire. The empty weight was light enough. Is that true?

If the overload is serious, it is recommended not to change the vacuum of the rear wheel.How much specific can light, this really did not study.

Q:What's the difference between 91V and 91W on a car tire?

W and V are the ultimate speed of said tire; the tire speed is also very different, the speed is a critical speed that don't tire: if the tire is traveling faster than the speed will be prone to burst dangerV stands for 240 km/h (high performance sports car); W stands for 270 km/h (GT sports car)

Q:How big are the world's largest car tires?

Michelin 59 / 80R63: by the Michelin Co production of tires is 4 meters high, 1.5 meters thick, weighs 5.5 tons

Q:Why aren't tires solid?

First of all, the aircraft tires are not solid. Most of the aircraft tires use tubeless, double tire tread structure, there is no inner tube. It doesn't mean solid. Two layers of special curtain are added to the tread rubber of the airplane tire, commonly known as "reinforcing cord ply."". With the ply as the boundary, the tread rubber is divided into the outer tread rubber and the inner tread rubber, and when the tyre is worn to expose the second layer of the curtain towel, the tire tread is scrapped. The rubber surface of the aircraft tire is made of wear-resistant and high temperature special material made of steel wire. It is about 20 millimeters thick and has high strength. The valve of the tyre is both sharp and short. It is made of high temperature fluoroplastic and the air intake is unobstructed. Aircraft tires have no inner tube, mainly for disassembly and maintenance, and they can be filled directly to the tire during flight. At the same time, airlines around the world are using high strength magnesium zinc alloy production hub and rim and hub of activity, and the activity of flange joint seal parts, valve and hub sealing ring, can ensure that the air in the tire up to a number of large pressure does not leak, the performance is ordinary tire can not be compared the cost is quite expensive, it.Ten tons of aircraft landing speed to hundreds of kilometers, the weight of the aircraft and the impact force on the ground, the tire rubber surface per square centimeter to withstand the pressure. Newton nearly no such a tire is not enough.
