What is the situation when both sides of the tire are worn?
3 Answers
Tire wear on both shoulder sides is a type of uneven wear, caused by underinflation or overloading. Below is relevant information about tire wear: 1. Solutions: The issue of 'tire wear' in semi-trailers is very common. It can be said that more than half of the semi-trailers on the road have varying degrees of tire wear problems. 'Tire wear' in trailers is a complex issue, with causes including the manufacturing quality of the trailer, usage conditions, maintenance, and the driver's skill level. However, in general, there are two main reasons for tire wear in semi-trailers: one is related to the design and manufacturing of the trailer, and the other is related to the owner's usual usage and maintenance. 2. How to avoid: During the design and manufacturing process of the trailer, factors such as the parallelism and symmetry of the beam, the degree of beam distortion, whether the suspension is installed correctly, whether the axles are qualified and installed properly, and whether the pre-delivery debugging is qualified can all lead to tire wear problems. For 'tire wear' problems caused by design and manufacturing reasons before leaving the factory, users generally find it difficult to solve after purchase. However, when selecting a trailer, users can choose to customize from large trailer manufacturers with relatively high technical levels, good reputation, and qualifications, which can to some extent avoid tire wear problems.
My car has been running for years, and I've seen the phenomenon of tire edge wear several times, which is basically severe wear on both sides of the tire while the center remains fine. Most of the time, it's due to low tire pressure. Insufficient pressure causes the middle of the tire to sag, making the edges contact the ground more and wear faster. I remember one time when I neglected the pressure, and after a long trip, the edges were nearly bald, almost leading to a blowout. Luckily, I went to the shop in time to inflate and inspect them. Other possible causes include incorrect wheel alignment—which makes the tires run at an angle, worn suspension systems, or taking turns too sharply, increasing load on one side. I recommend checking tire pressure monthly, keeping it at the value recommended in the car manual, and getting regular wheel alignments to prevent this. Otherwise, excessive wear not only shortens tire lifespan and costs more money but also increases driving risks, especially in rainy or snowy conditions when slipping is more likely. I set phone reminders and have made it a habit—much more convenient that way.
In car repair experience, customers often mention 'tire edge wear,' referring to rapid wear on the tire shoulders while the center tread remains relatively intact. This is usually caused by underinflated tires—when tire pressure is too low, the tire deforms, increasing stress on the edges and accelerating wear. Other common causes include misaligned wheel alignment (excessive or insufficient camber angle), damaged suspension components, or poor driving habits like aggressive cornering. The solution is straightforward: first, check and adjust tire pressure to the recommended level; if the issue persists, use professional equipment to inspect wheel alignment and adjust the suspension or replace worn parts if necessary. Don’t delay repairs, as this significantly shortens tire lifespan, increases fuel consumption, and poses safety risks, such as reduced grip at high speeds. I recommend a professional inspection every 5,000 km, especially for new car owners—start by monitoring tire pressure if unsure.
