A new study done by the National Highway Traffic Safety Administration has been released recently and shows that cars that have underinflated or worn out tires by more than 25 percent, are three times more likely to be involved in a crash.

Tires that are underinflated by up to 25 percent face the risk of overheating and this may also lead to failure. The study was done before tire pressure monitoring systems were installed in cars, between the years 2005 and 2007.

The new systems alert drivers if their tire pressure dips below 25 percent, but does not replace the need to get tires checked monthly. The study also found that nearly five percent of all of the vehicles in the study, experienced tire problems before the accident occurred. When tire failure is combined with other factors, such as adverse weather conditions, the likelihood for an accident to occur increases even more.
