What is the difference between 3-groove tires and 4-groove tires?
2 Answers
3-groove tires and 4-groove tires differ in terms of drainage and grip. Below are the detailed differences between 3-groove and 4-groove tires: 1. Key Differences: The main differences between 3-groove and 4-groove tires lie in their drainage capabilities and grip. 4-groove tires offer better drainage compared to 3-groove tires, whereas 3-groove tires provide superior grip over 4-groove tires. 2. Function: The grooves on tires primarily serve to channel water away and break the water film that forms on the tire surface on wet roads. This ensures better vehicle grip and enhances braking performance.
As a veteran long-haul truck driver, I've always felt that the difference in the number of tire grooves directly affects the safety experience during rainy driving. The 3-groove design is simple and practical, but with limited drainage channels, it tends to skid and lose control when turning on wet roads, making me feel uneasy. However, it performs steadily on dry highways, possibly slightly more fuel-efficient, suitable for driving on provincial roads in good weather. On the other hand, 4-groove tires have an additional drainage channel, quickly dispersing and expelling rainwater, significantly improving wet road traction. High-speed cornering feels stable, reducing accident risks. For example, during last year's heavy rain season, after switching to 4-groove tires, my car felt glued to the road, with the drifting sensation almost gone. The number of grooves isn't everything; tread depth and material are also crucial. Regular checks on tire pressure and wear can extend tire life. If living in a rainy region, I'd prioritize 4-groove tires for safety; for budget cars in dry areas, 3-groove tires might be considered to reduce costs.
