When this happens, the tread can start to separate, and this condition can be the start of a tire blowout. Just as bad on your tires is keeping the tire pressure too high! Over-inflated tires are stiffer and have less flexibility. Not only will you feel every dip and bump in the road with overinflated tires, when you hit a curb or a pothole your tire is more likely to suffer damage — including a blowout.
When you consider the rated PSI of your tires, remember there are also safe low and high limits that give you some wiggle room. But here we consider how easy, or how difficult it would be to over-inflate your car tires to the point where one would burst or pop. Nevertheless, the guys over at 'The Experiment' decided it was high time to discover just how much pressure a car tire can take. Taking a set of old, cracked, worn-out tires, the guys thought around psi — the maximum their compressor could deliver — would be enough to burst the rubber.
A fair assumption considering the average tire holds around psi. Alas, the tires stood firm under the pressure. Knowing that a pretty serious explosion was imminent, it was decided to move the experiment away from the back yard and into somewhere a bit more remote.
With the compressor made redundant, it was time to step up a gear and use a carbon-dioxide tank to deliver the requisite pressure to burst the tires.
Soon after, the rubber duly ruptured, with the sound echoing around the woodland like a gunshot and the tire flying 20 meters away into the bushes. Under-inflated tires can offer more resistance to the road, and thus make it harder for your car to push itself forwards. Only in extreme cases will you be able to tell if a tire is under or over-inflated just by looking at it, as anything less than 10 PSI either way is pretty much undetectable to the eye.
The only way to do it properly is by using a tire pressure gauge. You should aim to check your tire pressures at least once a month , and definitely before any long drives. This will go a long way towards preventing any possible danger while driving and minimize your risk of a blowout. But there are a few other things to bear in mind when you are checking your tire pressures. Higher temperatures will cause your tires to naturally increase in pressure , due to the proportional relationship between pressure and temperature.
Thus, you should always check your tires before driving, as they will heat up with the friction from the road, giving you a higher reading than when they are cold. You should also check them in the morning, before it gets warmer during the day. Manufacturers will provide their recommended tire pressures for your car assuming you are checking them cold, and so always try to do so in a cool environment.
There will also be different guidelines depending on how many people you will usually have in your car, and where they will be seated. This is once again to do with the weight on each tire. If you are travelling a long distance and need to bring lots of heavy bags with you in the trunk, check what the manual suggests for the rear tires, as it will probably be an increase versus the pressure for normal driving with no passengers or extra weight.
Tire pressures are very important to maintain, and there are a few signs you can look out for if you think your tires might be over-inflated. Thus, it is vital that you check your tire pressures regularly and monitor your tread too. Driving without the correct pressure in your tires can cost you more money in terms of fuel, but it will also make driving far more dangerous for you as well.

Consequently, the center wears out at a faster rate than the outer edges. It is possible that your tires will only reach half their actual lifespan. Aside from that, over inflating your tires can also cause traction loss.
Even when you drive on regular roads and conditions, over inflated tires can cause your vehicle to lose traction. This would lead to accidents. This problem becomes especially evident during the winter season. Your rides can become harsher as well. When tires are over inflated, they tend to give a bumpier rider. Needless to say, you will feel every dip in the road.
