How to Solve the Problem of Rear Tire Wear on Baojun 730?
4 Answers
The solution to the problem of rear tire wear on the Baojun 730 is to perform a four-wheel alignment. The main cause of rear tire wear is unequal wheelbase on both sides of the frame, which means one or several tires experience abnormal accelerated wear on the inner or outer side. Compared to the other tires, a specific part of one tire wears out much faster. The Baojun 730 is a family MPV under SAIC-GM-Wuling Baojun. It is equipped with a 6-speed wet dual-clutch transmission, and this automatic transmission can withstand a maximum torque of 360 Nm. In terms of power, the Baojun 730 is powered by a PTec DVVT 1.5T turbocharged engine, with a maximum power output of 150 horsepower and a maximum torque of 230 Nm.
I've seen this issue quite often. The rear tire wear on the Baojun 730 is indeed quite annoying, causing both tire waste and potential noise while driving. The key is to inspect the rear axle suspension system, especially for models with independent suspension, as misaligned four-wheel alignment parameters are the main culprit. You need to find a reliable tire shop with professional equipment to measure the rear wheel camber and toe angles. Additionally, aging or deformed rubber bushings on components like the rear axle control arm or trailing arm can cause the wheels to run crooked, inevitably leading to tire wear. I also recommend checking the rear shock absorbers, as oil leakage or failure can affect alignment angles. Once you identify the problematic component, replace the bushings if needed or adjust the tie rods accordingly. After completing the alignment, always test drive to confirm the results—don't just rely on computer data.
The issue of rear tire wear on a car is not something to be taken lightly. I suggest focusing on three key areas for inspection. The most crucial step is to get a wheel alignment done as soon as possible, paying special attention to the rear wheel data, as abnormal camber angles are often the main culprit. Open the trunk and lift the carpet to check for any signs of damage to the chassis, as rear-end collisions can cause deformations. Be mindful of your driving habits—avoid overloading the vehicle frequently or driving on rough roads, as these can damage the suspension. Additionally, assess the current wear level of the tires. If there is severe uneven wear, it’s advisable to replace them in pairs. Simply adjusting the alignment without replacing the tires is like wearing new shoes with old socks—it will still feel uncomfortable when driving.
I've experienced tire wear issues before, especially severe inner wear on rear tires. The key is to check suspension geometry parameters - using a laser alignment machine to measure toe and camber angles is absolutely necessary. The control arm bushings on the Baojun 730's rear suspension are prone to aging - poke around with a pry bar to check for play. For older vehicles, it's recommended to directly replace the entire control arm bushing set, as rubber components harden and crack over time. If the shock absorbers fail, it will affect vehicle height and alignment - remember to lift the car and check for oil leaks or spring fatigue. After replacing parts, you must perform bushing stress release before readjustment, otherwise the parameters will deviate again after a few days of driving. Don't try to save those few hundred bucks, or you'll end up wasting a whole tire which costs more.
