What to do about severe rear tire wear on the Haima S5?

The solutions for severe rear tire wear on the Haima S5 are: 1. Perform a four-wheel alignment; 2. Replace the tires. The maintenance methods for tires include: 1. Regularly check tire pressure to ensure it is neither too high nor too low; 2. Frequently remove debris from tire treads to avoid blowouts; 3. Inspect tire wear and replace them promptly based on wear conditions. The Haima S5 is a compact SUV launched by Haima Motors. Taking the 2019 Haima S5 manual elite model as an example, its body dimensions are: length 4418 mm, width 1823 mm, height 1630 mm, with a wheelbase of 2630 mm.

My Haima S5's rear tires wear out unusually fast, a problem I encountered last year. The inspection then revealed an issue with the rear axle suspension—the steering tie rod was deformed, causing uneven tire wear. After getting a four-wheel alignment at the repair shop, the situation improved significantly. The mechanic also taught me to measure tread depth monthly using a one-yuan coin. It's crucial to monitor tire pressure regularly: not exceeding 2.5 bar in summer and not dropping below 2.2 bar in winter. Aggressive cornering that causes the rear to slide excessively can lead to one-sided tire wear, so now I always slow down before turns. Thanks to these habits, I haven’t needed new tires in three years. If there are unusual noises from the chassis or the car pulls to one side, get it checked immediately—waiting until the tread wears down to the wear indicators risks a blowout.

As a seasoned Haima driver with 8 years of experience, rear tire wear should be checked in three steps. First, feel the tire surface with your hand. If only the inner side is worn flat, it indicates misalignment, while severe outer wear may suggest a damaged lower control arm ball joint. Next, check the tire pressure, as driving with prolonged underinflation is particularly harmful to tires. I always keep a tire pressure gauge in my car, maintaining 2.3 when the car is cold is ideal. Finally, examine driving habits; avoid exceeding 350 kg in load and drive slowly on bumpy roads. Last time I changed tires, I discovered wheel rim deformation, which is most easily overlooked. Remember to ask the mechanic to adjust the toe angle during alignment—factory settings are 0° for front wheels and 1.5° for rear wheels.

Don't rush to replace tires when encountering uneven rear tire wear. Once I noticed the steel belts showing on my right rear tire, and inspection revealed it was caused by shock absorber leakage leading to body tilt. Remember this three-step troubleshooting sequence: check suspension bushings - measure tire pressure - perform alignment. Replacing cracked bushings costs just 50-60 yuan, much more economical than buying a 400+ yuan tire. Regular front-rear tire rotation is crucial - I manually swap positions every 8,000 km. Always do wheel balancing when installing new tires, otherwise the steering wheel may vibrate at high speeds.
