Does the alignment problem cause uneven tread wear in my case?
2002 Camry LE, 4 cylinder, Michelin premier a/s performance h/v purchased in 2017, 60,000 mile tread wear warranty. The tread reaches the end of the life only after 33,000 miles, and the tread wear is uneven, i.e. outer tread worn more than the inner one. In contrast, the tread wear is even on my other car. Is the alignment the only cause for the excessive and uneven tread wear in my case? I’m really doubting. If not, what shall I check as the next step?
Here are the details. The outer most groove depths are 1/32” (front tires) and 2/32” (rear tires), and the inner ones are 3/32” and 4/32”. I found the car pulled slightly to the left on highway in 9/2020, and had the front wheels aligned, but the problem remained until at least 6/2021. The last 10,000 miles are mostly short trips less than 6 miles, but before that the trips were usually around 17 miles. The maintenance record is as follows, and the center column is the mileage.
