The wear degree of the four tires is abnormally high from time to time, which can usually be greatly lost within one thousand kilometers. The depth of the tire pattern is about 3 to 4 mm, the conditions are unknown, the repair shop has not found any mechanical failure of the suspension, the four-wheel positioning and dynamic balance have been checked, and no abnormality has been found.

We started our trip from Edmonton to Vancouver,2 adults 4 kids, no overloaded no speeding no tires scratching no off road route no slamming the brakes on. Pre-trip inspection confirmed that 4 tires had about 5 mini centimeter's tread left, it should be enough for at least 10 thousands km. After 800 km, the tire pressure warning red light came out, we found the left rear tire worn out entirely, the rest of 3 tires still had about 3 to 4 mini centimeter's tread left. We had the tire replaced and inspected for the car entirely for 2 times, cost us 600 dollars inspection charge for nothing! New tire tread had more than 1 centimeter. Then we head back, the new tire had only 8 mini centimeters tread left after 1300km way back.
