Why is the rear tire wear more severe than the front tires on the Outlander?
2 Answers
The reason for more severe rear tire wear compared to the front tires on the Outlander is excessive rear wheel camber deviation, which can be corrected through precise four-wheel alignment. The main causes of tire wear are: 1. Overinflation; 2. Underinflation or prolonged overloading; 3. Misalignment of front wheel positioning, with excessive front wheel camber; 4. Non-parallel front and rear axles. Taking the Outlander 2021 2.0L 2WD Changxing Edition 5-seater as an example, its body dimensions are 4705mm in length, 1810mm in width, and 1710mm in height, with a wheelbase of 2670mm. The front suspension type is MacPherson independent suspension, and the rear suspension type is multi-link independent suspension. The drivetrain is front-engine, front-wheel drive.
My Outlander has been driven for several years, and I noticed that the rear tires are wearing out faster than the front ones. This is usually related to vehicle design or driving habits. The Outlander is an SUV, and many models are rear-wheel or all-wheel drive, which puts more driving load on the rear tires. Additionally, I often carry heavy loads in the trunk, increasing the pressure on the rear tires and accelerating wear. Secondly, improper tire pressure can worsen the issue—low pressure increases friction, making the rear tires wear out more easily. Suspension problems might also be a factor, such as damaged rear shock absorbers causing uneven tire stress. It's recommended to first check if the tire pressure is correct by measuring both front and rear tires; the standard values are in the vehicle manual. If you've replaced tires or had a wheel alignment done yourself, have a professional shop recheck it to ensure accuracy. In short, during regular maintenance, ask the technician to inspect the rear suspension and braking system to prevent hidden issues. If this wear isn't addressed promptly, tire noise and fuel consumption will increase, affecting driving safety.
