National Transportation Safety Board (NTSB) data suggests that at least 33,000 crashes each year in the U.S. are attributable to tire issues in general. That federal agency specifically classifies 2,000 of those 33,000 as involving tire blowouts.
What are the odds of getting a flat tire?
In the United States alone, approximately 7 tire punctures occur every second, resulting in 220 million flat tires per year. Statistics also show that every driver will experience on average up to 5 flat tires in their life time. So the likelihood of running into such a roadside emergency is very high.
What PSI will cause a blowout?
The standard tire is inflated to about 30 to 35 pounds per square inch. Under hot weather and highway conditions, the temperature of the air inside the tire rises about 50 degrees. That increases the pressure inside the tire about 5 psi. The burst pressure of a tire is about 200 psi.
What if you have a blowout at a high rate of speed?
The blown tire is going to be a lot harder to roll, so you'll start slowing down immediately, and it will probably turn towards that side. Don't brake at first.
What is the most common cause of tire blowouts?
Most tire blowouts are caused by under inflation. Tire under inflation causes the side of a tire to flex more which generates heat. It's the heat that leads to the blowout. What's important to understand is tires lose pressure over time.
How common is it to get nails in tires?
This is a surprisingly common problem for drivers. Nails can get tossed aside during construction or fall out of open-ended pickup trucks. Because they are usually left lying flat on the ground, it might seem unlikely that they can pierce tires.
