The PSI at which a tire will explode depends on the tire but most often it's 200 PSI at which most tires will explode.

Smaller Tires may explode when inflated to 100 PSI or 150 PSI.

A tire can explode from too much air.

If you put too much air into a tire then eventually the tire will explode and cause serious injury to yourself or others or even death.

There have been people who died from inflating tires too much which then caused it to explode which is why a tire cage is a good idea when airing up tires and especially when mounting tires on rims or those large tires.

Tires can explode when going down the road from too little air and too much air as well.

Tires can split due to age, manufacturing defects, driving too fast, spinning out, abuse of the tires and over inflation.

Aging of the tires is one of the most common causes of tires splitting as when the tires age the tires start to break down as the rubber ages and starts to crack which then leads to them splitting.

Having a misalignment of your wheels can also cause the tires to wear unevenly and lead to tires splitting and separating.

Tire tread separation will typically sound like a loud thump as you go down the road and it will usually continue making a loud thump, thump, thump, thump, thump sound until the tire blowouts and you lose control.

If you hear a loud thump, thump, thump sound you should pull over and check the tire before it blows out.

Tire tread separation is one of those things that is exactly what it sounds like.

When the tread of your tires (the outer part of the tire with grooves in it that uses grip to keep you on the road) starts to come off of the body (also called the casing) of your tire, that's tire separation.

Tire belt edge separation is when the tires belts underneath a tire's tread come apart.

When the belt edge separation of the tire happens, the tread itself begins to come off the rest of the tire.

This can be really dangerous at highway speeds.

Many drivers lose control, and some vehicles crash or roll over.

Tire delamination is when the tires tread separates from the tires casing.

When tire delamination occurs the tire is basically just tearing itself apart with the outer and inner components separating.

The bond between the casing and the tread can be compromised and lead to tread separation for a variety of reasons, including manufacturer's defects, tire abuse, incorrect flat repair, underinflation and excessive tire wear.

Radial tires are constructed by laying steel belts between layers of rubber and composite.

Each layer is a "plie" and these plies are laminated to one another when the tire is created.

If the steel belts become warm enough (typically because of under-inflation), they can separate from the rubbers plies, aka "delaminate."

If you notice tire delamination you need to change the tire and have a new tire put on the rim.

Driving with a tire delaminating means that the tire could blow out soon and at high speeds that can be really dangerous and even lead to a fatal crash.

Always replace tires when needed as they are not something you want to cheap out on.

Some peoples tires age and crack and delaminate before the tread actually wears down and regardless of tread wear the tires should be replaced every 8 to 10 years.
