Worn Treads. On a typical passenger vehicle, a healthy tread should measure above 4/32nd of an inch.
Bulges and Blistering. When the tire's sidewall weakens, odd bulges or spiderweb cracks may start to appear. You’ll want to have these inspected right away to avoid a potential blowout.
Brake Pedal Vibration. If your pedal shudders or bounces when attempting to slow or come to a full stop, it means your tires aren’t properly gripping the road and might need to be inflated or replaced.
Slow Leak. If while driving you notice your Tire Pressure Monitoring System light continually appearing, there’s a good chance that at least one tire has a small puncture or leak.
