Lately I experienced something unusual on my ride, my Michelin tires have wear out on one of the tire’s shoulder as below:
Michelin Tire wear on one shoulder
From the above image, the wear or damage on the tire clearly indicate that my Toyota Vios suspensions alignment are misaligned.
The event is so happened I was in business trip around Rawang, Selangor. I went to one of the tire shop known as Toyo Tyre, in Rawang. The staff told me that my camber bolts required to replace after they tried to alignment my both front wheels but failed.
They indicate the OEM camber bolts unable to make adjustment to correct back the alignment setting of the car, thus they suggest to replace the adjustable camber bolt for me.
If you are not too sure how the camber bolt affecting the tire setting, below image able to explain well:

Technical, chamber bolts are use to hold the upper control arm to the knuckle assembly on wheel. Adjustable camber bolt has more flexibility to align the wheel to the right angle and position.
Below image is the adjustable camber bolt:
