Now that pace of people's lives is getting faster and faster, efficiency of travel is extremely important, and there are various modes of transport to choose from. A car is a fast and efficient means of transportation. The status of car in all modes of transport is obvious, so it is very important to ensure safety of car! At present, country also pays great attention to road safety, detailed traffic rules have been developed, they cooperate with relevant departments such as traffic police to maintain order, in addition, surveillance cameras are installed at large intersections, so traffic order in our country is gradually becoming more and more ordered.
Tires are an important guarantee of safe driving and should of course be checked frequently. Especially before you go on a high-speed or long-distance transportation, it is necessary to conduct a comprehensive inspection! In addition to checking whether tire pressure is normal, it is also necessary to check wear of car's tires. Once a problem is detected, it must be corrected in time. Only after all these potential safety hazards have been eliminated will you be able to drive with confidence. Friends who often deal with cars will find that there are various patterns and grooves on surface of tire, but some grooves have three grooves, while others have four. What is difference between three grooves and four grooves on a car tire? It wasn't until I knew reason that I realized there was such a big difference!
1. Drainage
Bad weather conditions are unavoidable in daily travel. In heavy rain, road surface becomes very slippery, which also affects tires. Because at this time, a water film will form between wet road and tire, so tire will slide. This groove can also be called a water guide groove. Then three-groove tire is compared with four-groove tire, of course, four-groove tire has better drainage performance. Those tires with deeper patterns and more patterns on market have relatively better water evacuation.
2. Capture
Propelled by power of engine, car gives earth a frictional force through tires, and earth at same time creates a reaction force, thereby pushing car forward. That's how cars drive, but that friction is also a clutch. There are many factors that affect traction and tires are one of most important factors. The greater contact area between tire and ground, greater grip. Compared to four-groove tires, three-groove tires have a larger ground contact area. Therefore, in terms of traction, tires with three grooves are better.
3. Garbage in trench
Because a four-groove tire has one more groove than a three-groove tire, grooves will contain more rocks, broken glass, and other debris. In fact, these little things wear car tires slowly and will be very difficult to deal with after a long time, so it will also have a certain effect on life of car tires. If a tire bursts, consequences would be unimaginable, so our car owners must carry out daily maintenance to prevent accidents.
Based on results of comparison, three-groove tires have advantages and disadvantages compared to four-groove tires. Drainage characteristics and adhesion characteristics are inconsistent and cannot be same. Car owners can choose suitable tires according to their needs. These tires are designed to enable vehicles to better adapt to different road conditions, with ultimate goal being to ensure everyone's driving safety. To have a safe travel environment, it is useless to rely solely on strict control of country, and we need to work together, because a good travel environment can bring us great convenience!
