When you ride with your tires underinflated, the wear shows on both outer edges of the tire.
This is the most common.
Your TPMS (tire pressure monitoring system) alerts you when your tire pressure is about 25% below the recommended amount.
The problem with that is, if you were to drive at 20% lower than recommended amount, for the life of the tires,

When to change your tires
One of the ways to determine when it's time to change your tires is to check the tire tread depth.
We use a specific tread depth gauge.
At 3/32 of an inch your tires will not perform properly.
We check the wear patterns for improper tire wear. All tires have wear bar indicators as seen in the picture.
If the tread of the tire is near flush with these wear bars, then it's time to change your tires.
Of course there is the time tested quarter method. Stick the quarter in between the treads, catch a side view of it.

NOTE: Additionally, your tires should not come into sustained contact with gasoline or oil.
Improper storage will rapidly accelerate the normal aging process, making your tires unsafe.
