Tire Wear Indication

Here are things to check when inspecting your tire. The wear pattern will indicate the kind of issue you might be experiencing 

Centre Tread Wear - if you are noticing wear in the center of the tread it is often due to overinflation.   Inside the driver's door you will find a sticker sticker indicating the proper inflation.   The side wall of the tire will also indicate proper tire pressure.

Edge Wear - Underinflation is the typical of tires wearing at the edges.  Aggressive driving can cause wear at the outer edges.  

Wear on One Side - With this type of wear, the inside of the tread shows more wear than the outside, or vice versa. Poor alignment, worn ball joints, or other worn or bent suspension parts might be the cause. Bring your car in for a proper alignment and an inspection of your suspension components.

Feathering - If one side of your tread is rounded on one side and one site is pointed such that each tread is worn in one direction.  Your vehicle may have a toe in alignements,  Some feather can be caused by a lot  high-speed driving.

Cupping - Scalloped dips or rounded near one edge of the tread might indicate issue with worn suspension.

Bald or Flat Spots can be caused by a number of factors such as skidding in older cars without abs. Drivers will notice an imbalance and vibration in the steering wheel. It may also indicate a wheel of out balance. 

Damage, Swelling or bubbling. And damage bubbles, tears, or bulges that are visibly in the sidewall or tread should be inspected by a professional and will require a repair or replacement.
