What happens if your tyres are too inflated?
One of the most crucial aspects of inflating a tire is getting the proper pressure. Both under- and over-inflating a tire can have a negative impact on a vehicle’s performance and tire life.
When you over-inflate a tire, the air pressure inside the tire rises, putting more pressure on the inner walls of the tire.
This rise in pressure causes the insides of the tire to become stiffer than normal, reducing its performance and hurting the vehicle’s overall performance in a variety of ways.
Tire sidewalls and tread grow tougher than normal as a result of over-inflation. This can affect the tire’s traction and performance, as well as cause uneven wear. The contact patch of the tire really shrinks when the pressure is increased beyond the recommended amount. Because of the increased pressure, the tread center protrudes further out than the remainder of the tire tread. This is a concern since the majority of the traction now comes from the center of the tire, which reduces the overall contact patch of the vehicle. This is also why over-inflated tires exhibit uneven wear in the center. Because the center of the tire makes more contact with the road than the outside edges, over-inflated tires will show evidence of accelerated wear along the center. Because the engine now needs to work harder to compensate for the lower contact patch, this identical loss in contact surface might result in a decline in mpg.
Over-inflating tires can have a negative impact on a vehicle’s performance, as well as the vehicle’s comfort and safety.
Tires that are overinflated offer a harsher, more unstable ride than tires that are correctly inflated.
Tire sidewalls are designed to support the vehicle while also absorbing some of the shocks and bumps that the vehicle encounters as it travels over the road surface. When a tire is overinflated, the sidewalls grow tougher, and instead of absorbing road bumps and shocks, they are delivered directly to the suspension of the car. This may result in a rougher ride as well as higher tire road noise. When dealing with older or significantly overinflated tires, the sidewall of the tire may be at risk of blowing out due to the increased pressure.
It is typically recommended that a vehicle’s tires be inflated to the manufacturer’s recommended pressure, never exceeding the maximum pressure shown on the sidewalls.
The best approach to ensure that you get the finest performance and the longest life out of your tires is to keep them at the recommended pressure and rotate them at regular intervals.
Compromised Safety
When you drive on overinflated tires, you risk a range of problems. Overinflated tires, on the other hand, are more likely to blow out. A flat tire can cause you to lose control of your car and reduce braking distance, putting you and others on the road in risk.
Furthermore, several of your vehicle’s safety features, such as your anti-lock brake system, are designed to work when tires are filled to the manufacturer’s specifications. Some of your car’s driver assistance systems may be jeopardized if your tires are overinflated.
Tire Damage and Wear
Tires that are overinflated are more susceptible to damage. Tires packed to their maximum capacity, like an overfilled balloon, become stiff and inflexible, making them more susceptible to damage from potholes, curbs, or debris. Furthermore, as a driver or passenger, you will feel every bump and dip in the road, which is not a pleasant experience.
Excessive air pressure can also deform the shape of the tire, resulting in less grip and more wear and tear in the center. Repeatedly overinflated tires may wear out more quickly depending on the circumstances.
When you overinflate a tire, it bulges in the center of the tread. A little, slender area in the middle of the tire is the only section of the tire that touches the road. According to Popular Mechanics, “this should mean less rolling resistance and increased mileage.” But what about in reality? It means uneven tread wear in the center, a bumpy ride, and a higher danger of a blowout.
It’s worth noting that a few PSI above your recommended tire pressure won’t put you in danger. Tire pressure, after all, varies with the ambient temperature. Your goal is to maintain the cold tire pressure recommended by your vehicle’s manufacturer.
What happens if your tyres are under-inflated?
Over-inflated tires show wear down the center of the tread, whereas under-inflated tires show wear on the outside margins of the tread. In any case, inadequate inflation pressure leads to uneven wear, faster tire wear, and less money in your pocket.
What is the best way to fix under-inflated tyres?
It is simple and quick to inflate the tires on your car. However, in order to execute it properly, it’s best to plan ahead of time.
To begin, ensure sure your tires are completely cold before inflating and monitoring the pressure. It would be great if you did it first thing in the morning or after only a few miles of driving. After a long ride, never check the pressure.
Then get some tools ready. You’ll need a tire pressure gauge to check the pressure in your tires. Gauges are now relatively affordable, and they are also small enough to fit into the spare tire compartment.
To fill the tire, you’ll also need an air pump. There are several different types of air pumps, including hand-operated, foot-operated, and automatic air pumps.
Air pumps that are controlled by hand or foot are less expensive, but they require significantly more force and take longer.
Automatic air pumps are normally connected to your vehicle’s 12V plug, making the process much faster and more convenient.
Step 1. Remove the Valve Stem Cap
Remove the plastic cap that covers the valve stem and unscrew it. You may also need to remove the wheel cover on steel rims with wheel covers. Put the plastic cap somewhere safe because you’ll need to screw it on later.
Otherwise, dirt and debris may collect in the valve stem, obstructing your ability to inflate or measure the pressure in your tires.
Step 2. Use a Tire Pressure Gauge to Measure the Existing Pressure
Place the valve stem with the end of the tire gauge’s hose. So that there is no hissing noise, push as hard as you need to. Then double-check the reading the needle on analog gauges should jump right away. However, on digital gauges, you may need to press a button to activate it.
Step 3. Check the Recommended Tire Pressure for Your Car
It’s best to check the measured pressure inside the tire to the prescribed pressure first. The appropriate tire pressure is displayed on a sticker on the driver’s or passenger’s door sill. If you can’t locate it there, the owner’s handbook is the best place to look.
Step 4. Inflate the Tires Using an Air Pump
Place the hose’s end on the valve stem and secure it in place with a clamp. You won’t be able to inflate the tire if you hear a hissing sound. The tip of the hose may need to be firmly placed against the valve stem on some air pumps.
Then begin pounding for a few minutes. Tire pressure should be checked every 15-30 seconds, as overinflated tires will not function effectively. And don’t worry if you overinflate the tire. The tire will begin to deflate if you press the core of the valve stem with a sharp tool.
Replace the plastic cap over the valve stem once you’ve reached the recommended pressure.
Step 5. Inflate the Tires at the Nearest Gas Station (Optional)
Low tire pressure can also be repaired at the local gas station. At gas stations, the air pumps will automatically reach the desired pressure. Simply set the apparatus to the recommended pressure, connect the hose to the valve stem, and listen for the sound signal.
Why do vehicle dealers inflate tyres too much?
Tires are overinflated during transportation to assist prevent flat spots from growing in the tire as it sits for days on end. The service staff is supposed to deflate the tires to the right pressure as part of the delivery inspection process.
Is a pressure of 3 psi excessive?
All four tires on my 2017 Toyota Tacoma require 33 pounds of air. Temperatures in my area can swing from the high 70s to the low 20s and back to the high 50s within two or three days, depending on the time of year. This makes maintaining tire pressure difficult. My inquiry is: What are the safe tire pressure high and low limits? I know that if I use 35 psi, I’ll have a more difficult ride and higher gas mileage. I’ll get a softer ride and worse gas mileage if I go with 29 psi. When, though, do I need to alter it in either direction for safety reasons? Gary
When it comes to tire pressure, Gary says it’s always better to go too high than too low (to a point).
As you mentioned, tire pressure varies with outdoor temperature. Tire pressure changes by around 1 psi for every 10 degrees change in outdoor temperature. If you fill your tires to 33 psi when the temperature outside is 75 degrees and the temperature drops to 25 degrees at night, your tires will be at 28 psi. That’s a ridiculously low figure.
Most tire-pressure monitoring devices, according to what I’ve heard, alert you when your tire pressure drops by roughly 10%. For you, 10% equals a little less than 30 pounds per square inch.
Tire pressure that is too low is always more dangerous than tire pressure that is too high. When tires are deflated, more rubber comes into contact with the ground, the tires heat up, and you risk a blowout. If you recall the Firestone/Ford Explorer debacle, heat (high road temperatures) and low tire pressure were the aggravating elements that led to many of the defective tires exploding.
As long as you stay well below the “maximum inflation pressure,” higher pressure is often not harmful. This value is printed on each sidewall and is far higher than Gary’s “recommended tire pressure” of 33 psi.
So, in your instance, I’d propose setting the tire pressure to 35 or 36 psi and leaving it there. There will be no change in tire wear, handling, or braking.
Even if the temperature drops by 50 degrees, you’ll still have 30 psi or more, keeping your “low pressure” warning light off.
There will be no harm done if the temperature rises in the opposite direction. Gary, as you say, at worst, you’ll get better gas mileage and a somewhat firmer butt massage when driving about.
Should you inflate your tyres more in the winter?
Is it bad to have overinflated tires in the winter? While cooler weather may necessitate more frequent re-inflation, this does not mean your tires should be overinflated. Here’s what you need to know about overinflated tires and why it’s especially vital to maintain track of tire inflation during the winter months.
Cold Weather Changes Tire Pressure
Your tire pressure was probably great throughout the summer and even into the fall, but now that winter has arrived, that pesky tire pressure indicator may start blinking again. What’s going on here that’s causing this? Most things expand when they’re hot and contract when they’re cold because molecules become excited in the heat and slow down as the temperature drops. This applies to the air in your tires as well. When it gets cold enough, the air contracting in your tires lowers the pressure, resulting in an underfilled tire that you may not notice.
Low tire pressure necessitates adding air to your tires in order to avoid handling concerns, early wear, poor gas mileage, and other issues. However, this does not imply that you should inject air in excess of the manufacturer’s instructions.
Overinflated Tires Can Lead to Tire Damage
Tires that are overinflated have their own set of issues. Overinflating your tires can result in a bulge in the tread, causing early and uneven wear. It can also make them more vulnerable to potholes and curb damage. You’ll need to replace your tires more frequently if they’re overinflated, and new tires aren’t inexpensive.
What About Traction?
Even though tires might be rather huge, only a small section of each tire is ever in contact with the road. The contact patch is what provides your tires traction and allows them to move where you want them to go when you spin the wheel. An overinflated tire’s tread surface bows out, resulting in a smaller contact patch and reduced grip. A tire pressure gauge is useful to have on hand in case you have any doubts about your tire pressure.
Overinflated Tires in Winter
Overinflating a tire is never a smart idea, but it’s especially harmful in the winter. Snow, ice, salt, and sand that accumulate on ordinarily clear roads throughout the winter can impair grip, so you’ll need to do everything you can to acquire as much traction as possible. In the winter, the likelihood of uneven or excessive tread wear increases dramatically because an overinflated tire already has less traction due to its smaller contact patch.
When the temperature drops, you may need to add more air to your tires, but don’t overdo it. To guarantee good wear, proper traction, and optimal tire safety, inflate your tires to the manufacturer’s requirements.

What PSI does a tyre explode at?
Is it possible to increase tire pressure without physically filling the tire? I was going from Flagstaff, Ariz., to Tucson when the tread on the front driver’s side tire blew off 30 minutes from Tucson. The tire technician checked the pressure and concluded that air had been added to the tire during an oil change or something similar. But it had been a while since there had been any sort of service. Is the tire affected by altitude, barometric pressure, heat, or speed? It’s a 1991 Honda Accord with 198,000 miles, just in case you were curious. Bryan’s words
TOM: Bryan, you’re a lucky man. When one of the belts snaps, the entire tire can come apart. This includes the atmosphere. And at highway speeds, that can be a lot of fun!
RAY: To address your query, over-inflation was most likely unrelated. It had more to do with your tires’ age and condition.
TOM: We checked with Bill Woehrle, the Quincy, M.E. of the tire world, for more information.
RAY: Bill worked as a tire engineer for many years and now heads TFI: Tire Forensics Investigation, which will air on CBS next fall.
TOM: According to Bill, over-inflation nearly never results in tire failure. The typical tire pressure is between 30 and 35 pounds per square inch. The temperature of the air within the tire climbs to around 50 degrees in hot weather and on the highway. This adds around 5 psi to the pressure within the tire. A tire’s burst pressure is around 200 psi. So, unless your tires were pushed up to 195 psi (which, trust us, they weren’t), you didn’t come close to bursting the tire due to excessive internal pressure.
RAY: According to Bill, the most vulnerable section of any steel-belted radial tire is the area where the steel belts are linked to the rubber along the tread edges, often known as the “shoulders.” Those belts should stay attached to the rubber for the whole tread life of the tire if it is not misused.
TOM: However, the top belt can separate if the tire is defective (see the Firestone debacle) or abused in some way at the end of its useful life (and since you drive a car with 198,000 miles on it, Bryan, we can’t help but wonder if those tires are older than the polyester leisure suits in my brother’s closet). It tears aggressively, so it’s a crapshoot whether the following layer of rubber will tear as well, resulting in a blowout.
Under-inflating your tires is the most typical form of abuse. That’s true, they’re being under-inflated.
TOM: All right, let’s get back to our forensic tire expert. Under-inflating the tire, according to Woehrle, adds to the tension on the tire’s shoulders, where the belts are linked. The temperature at those shoulders can exceed 200 degrees if a tire is under-inflated by 10 or 15 psi. So you’ve got a hot, sensitive section of rubber being stretched and tugged, which is a formula for tire failure.
By the way, overloading the automobile with things like luggage or two mothers-in-law is the same as under-inflating the tires. It puts a strain on the tire shoulders.
TOM: So, according to Bill, it’s better to over-inflate your tires a little than under-inflate them if you’re going to make a mistake with your tires. Over-inflating the tires by 10 or 15 psi has no negative consequences other than the fact that you’ll bounce up and whack your head on the dome light while going over bumps.
RAY: However, under-inflation poses the risk of catastrophic tire breakdown. As a result, for all of our readers: Make sure your tires have enough tread and haven’t exceeded the mileage rating set by the manufacturer. Even if they have minimal mileage, make sure they’re under 10 years old (because old rubber gets brittle and has a greater tendency to crack). Also, make sure your tires aren’t under-inflated by checking their pressure at least once a month.
