Do bad tires make noise?
The unbalanced tread depths cause tires to emit loud noises while driving. Usually, you'll hear sounds caused by uneven wear coming from one tire. This will cause irregular tire movement and make the sounds coming from the air chamber louder. A bad wheel bearing is one of the more serious issues that cause tire noise.
How long do tires last before they dry rot?

Why do tires split on the side?
When the tire gets excessively hot, the rubber begins to degrade, which if driven on long enough, leads to a rupture in the sidewall of the tire, or tread separation. In addition to the sidewall splitting, the inner liner will usually have evidence that the tire was run at low air pressure before it exploded.
