The increased pressure causes the center of the tread to protrude further out than the rest of the tire tread. This is also why overly-inflated tires show signs of uneven wear along the center. Over-inflated tires will show signs of accelerated wear along the center, because the center is making more contact with the road than the outside edges are. This same decrease in contact surface can also cause a drop in mpg, as the engine now has to work harder to compensate for the reduced contact patch.
Over inflating tires can not only be detrimental to the performance characteristics of a vehicle, it can also take away from the comfort and safety of the vehicle as well. Overly-inflated tires will also cause the vehicle to have a harsher, more unstable ride than properly inflated ones.
This can result in a harsher ride, as well as increased road noise from the tires. Keeping the tires at the suggested pressure, as well as rotating them at regular intervals, is the best way to ensure that you get the best performance as well as the longest life out of your tires.

It is determined by a series of tests and analyses for each model, and takes into account several factors: Tire wear and tread life Driving comfort Fuel efficiency Handling Exceeding the manufacturer's optimum tire pressure is not recommended for the following reasons: Tires will wear out prematurely.

Ownership tire pressure. 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. Flow Racers is a reader-supported site.

The 4 symptoms of over-inflated tires are: Lack of traction Excessive wear on center treads An uncomfortable ride The car behaving oddly Below, we will look at why your tires might be over-inflated, and some good practices to ensure you always have the right amount of pressure in yours. What Is Tire Pressure? Excessive air pressure can also distort the shape of the tire, leading to decreased traction and increased wear and tear down the center of the tire.
Depending on the circumstances, repeatedly overinflated tires could wear out more quickly. A tire bulges in the center of the tread when you overinflate it. The only part of the tire touching the road is a small, skinny patch down the middle. In theory, "this should mean less rolling resistance and increased mileage," notes Popular Mechanics. But in reality? It means center tread wear, an uncomfortable ride, and increased risk for a blowout. Note that a few PSI over your recommended tire pressure generally won't put you in the danger zone.
After all, tire pressure fluctuates with the outside temperature. Don't worry—fixing this air pressure problem is a breeze. To get the most accurate tire pressure reading and inflation, follow these steps when your tires are "cold," either in the morning or after the car has been sitting for a few hours.
Topping off warm tires may result in over-inflation.
