Tire pressure and performance changes can happen as a result of cold temperatures and winter conditions, and these changes must be monitored.
The actual PSI level of your tire will be determined by the specs of your vehicle however, in the winter, you should keep it between 30 and 35 PSI. This helps to ensure that your tires are performing at their peak levels in terms of safety, performance, and fuel efficiency.
Tire pressure changes significantly depending on the tire type and driving conditions. As winter approaches, it is critical to understand the optimum tire pressure in order to maximize the performance of your vehicle. Anyone who has driven in the winter with their tire pressure gauge flashing will understand how quickly a tire loses air due to the freezing temperatures. This article will show you how to properly inflate your tires in preparation for winter driving.

Is Lower Tire Pressure Better In The Winter
Reduced tire pressure might help you handle icy roads, especially when the plow hasnt been through yet. However, once those roads are plowed and sanded, the decreased pressure will be a major barrier. Lower pressures expand the rubber in contact with the ground. This helps disperse the weight of your car across more snow. Thats perfect for back roads and driveways that dont get plowed often.
However, when you reach well-maintained roads, that decreased pressure will make it difficult to steer consistently or properly. All that additional rubber will make your tires handle poorly, but thats not the worst of it, due to underinflation, the tires are prone to overheating. It doesnt take much for your tires to get hot enough to explode or pop when driving in a snow storm. In an emergency, decreased tire pressure can help but generally, you want to keep your PSI between 30 and 35 PSI.
What If Your Are Using Different Tires Than What The Vehicle Manufacturer Recommends
Another common question from people is what if Im no longer using the same brand of tire that came on my car? Most people will end up having to swap out tires during the ownership of a vehicle and likely wont go with the same brand of tire that they are replacing. That is totally fine. If this applies to you then you should still inflate your tires to what the vehicle manufacturer recommends.
Different tires may have different max PSI ratings depending on the type of tire. However, you would want to inflate your tires to whatever your vehicle manufacturer recommends. This is going to give you the best ride quality for your specific vehicle.

What Is The Recommended Tire Pressure
The recommended pressure for tires varies by the type of car and tire. Because maintaining your tires is so crucial to your safety and your cars overall performance, its important to know what tire pressure is correct for your vehicle.
To learn what your tire pressure should be, look for your manufacturers recommendation, which is printed on a label inside your car. Depending on the vehicle, this label may be on the edge of the vehicles door, on the doorpost or in the glove box. The label will usually give recommendations for the front and rear tires as well as the spare, and its important that you stick to those guidelines. Even after youve replaced your tires, the same pressure guidelines on your cars label apply to new tires of the same size.
Pressure recommendations are based on readings taken from a tire pressure gauge. Check the pressure first thing in the morning or wait at least three hours after driving this provides sufficient time for them to cool back down.1
Should Tires Be Inflated To Max Psi
Many people underestimate the importance of properly inflated tires. Whether it is a cars tire, trailer tire, RV trailer tire or a boat trailer tire, properly inflated tires are always important for safety on the road.

Start With Cold Tires If Possible
Vehicle manufacturers specify PSI â literally âpounds per square inchâ of pressure â assuming tires are cold. Tires are considered cold when the vehicle has been parked for three hours or more, or if the vehicle has been driven less than a mile at moderate speed. PSI is the unit your pressure gauge uses to provide readings.
How Does Tire Pressure Affect Driving
Both overinflation and underinflation affect your tire performance a lot, and serious problems might occur. According to NHTSA, driving on underinflated tires increases a driver’s chance of being in a serious accident by 300%. So how will a bad tire pressure affect driving safety? We will explain in detail below.

Kids Bike Tire Pressure
Kids tire pressure should always trend toward the low end of the range printed on the tire wall. The lower pressure is because kids are light, and they benefit from the added grip and comfort of a low psi, promoting enjoyable and confident riding.
For more experienced children and those riding just on pavement, raising the psi to reduce rolling resistance on smooth surfaces is acceptable. Kids wheel sizes and weight vary greatly, so take these estimates lightly and consult the manufacturers recommendations.
- Mountain bike = 18 36
- Hybrid bike = 30 60
What Happens When Your Tires Are Overinflate Or Underinflate
When you drive with over-inflated tires, you risk:
- Problems with handling and safety. Your tires cant give as much on the sidewall, and precise braking could be compromised. Youd also be risking reduced traction.
- Rapid, uneven tire wear. Your tire will wear much faster, and only in the center because the rubber will bulge in the middle, increasing that areas contact with the road.
- Blowouts. Bald strips cant dissipate heat as well, and that means your tires can suddenly blow out.
When you drive with under-inflated tires, you risk:
If youve been driving with your tires over-inflated or under-inflated, immediately deflate them to the manufacturers recommended pressure for your driving safety. If youre not confident about how to check your tire pressure, follow our handy 5-step Guide to Checking Tire Pressure.
When your tires are consistently inflated to the recommended air pressure, you enjoy greater tire life, performance and safety.

If You Use Wider Tires
Wider tires like mountain bike tires hold a larger volume of air than much skinnier road tires. Because they hold more air, the pressure inside doesnt need to be as high to achieve the same degree of tire firmness when compared to narrow tires.
For example, a road bike tire might have a PSI range of around 80 to 120 PSI, while a mountain bike tire is typically inflated to 30 PSI or less. Both tires might feel the same when you squeeze them, despite their vastly different tire pressures.
Commuter Bike Tire Pressure
Commuter and hybrid bike tire pressure lies in the middle of the road and MTB ranges.
Rider preferences and terrain are the two primary considerations performance is not significant for commuter or hybrid riders.
Because performance is less of an issue, you can allow more flexibility in the ranges. In addition, many commuters carry cargo requiring an extra 2-4psi per 10lbs of cargo.
Maintain a mid to high PSI for fast commutes on smooth city roads experiment with the lower end of the range for mixed terrain and frequent wet weather.
- 35mm = 50 80psi
- 38mm = 40 70psi

Can You Drive On A Tire With 28 Psi
Most passenger vehicles recommend 33 to 35 psi. At 28 psi, youre running a little low and really should get them aired back up. Thats not what I would call alarmingly low, but anything more than three or four pounds below normal can cause handling problems and increases the potential for a blow-out.

Car Talk: When It Comes To Tire Pressure Too High Better Than Too Low
Dear Car Talk:
My 2017 Toyota Tacoma calls for 33 pounds of air in all four tires. Where I live, during certain times of year, temperatures can range from a high in the 70s to a low in the 20s and back to a high in the 50s, all within two or three days. This makes tire pressure difficult to maintain. My question is: What are the safe high and low limits for tire pressure? I know if I go with 35 psi, I will have a hard ride and better gas mileage. If I go with 29 psi, I will have a softer ride and worse gas mileage. But for safety, when do I need to actually adjust it, in either direction? Gary
Its always better to go too high than too low with tire pressure, Gary .
As you say, tire pressure changes along with the outside temperature. For every change of 10 degrees in the outside temperature, tire pressure changes about 1 psi. So if you fill your tires to 33 psi when its 75 degrees out, and it drops to 25 degrees at night, your tires will be at 28 psi. Thats too low.
Ive been told that most tire-pressure monitoring systems warn you when your tire pressure drops by about 10 percent. For you, 10 percent would be a little less than 30 psi.
Low tire pressure always is more dangerous than high tire pressure. When tires are deflated, more rubber touches the ground, the tires heat up and youre in danger of a blowout. If you remember the Firestone/Ford Explorer fiasco, the aggravating factors that led to many of those flawed tires exploding were heat and low tire pressure.

How To Check Tire Pressure At A Gas Station
If youre at a gas station, you may not have a tire gauge to check the pressure. But many gas station air pumps have a gauge attached to the air nozzle that will pop up to tell you the pressure. Keep in mind that your tires are probably hot, which means youve been driving on them. In this case, add 2-4 PSI to your tire pressure over the manufacturers suggested PSI.
How Do Extremely Warm Temperatures Affect Tires
Any increase in temperature can raise the PSI of your tires. The higher the temperature becomes, the higher the pressure in your tires will be.
In places where the temperature only rises by 10 or 15 degrees, your tires will only gain about 1 PSI.
Typically, that isnt going to be enough to cause major damage to your tires.
That said, summer weather in some places may cause the temperature to rise by 20 degrees or more.
If the pressure in your tires begins to rise by 2PSI or more, it increases the chances of dangerous levels of over-inflation.
When over-inflation happens, you may notice problems with the way your car drives. Braking may become more difficult, and your tires may be more likely to be punctured by objects on the road.
Because of that, its extremely important to check your tire pressure regularly when you expect large changes in temperature.

Is 35 Psi Too Much For Tires
Higher pressure generally is not dangerous, as long as you stay well below the maximum inflation pressure. That number is listed on each sidewall, and is much higher than your recommended tire pressure of 33 psi, Gary. So, in your case, Id recommend that you put 35 or 36 psi in the tires and just leave it there.
What Psi For Mountain Bike Tires Is The Best
There is no best tire pressure. Its because you need to consider several factors that affect how hard or soft your tires should be.
Getting the correct tire pressure also boils down on your preference when riding your bike. You also need to consider your chosen discipline such as XC or downhill, among others.

What Psi Should My Summer Tires Be At
During the summer, PSI should still be within the normal range but the issue comes in when taking the reading.
As stated previously, it should be taken when the tire is cold but the summer heat makes this harder to do.
Try taking the reading before you start driving, and ensure the vehicle hasnt sat for too long in direct sunlight as this could impact the result.
Depending on what the pressure was before the environmental temperatures went up, you may need to manually reduce it to keep it within the normal range.
Why Are You More Likely To Receive A Puncture With Higher Levels Of Psi In Your Tires
For the same reason, you are going to feel every bump and dip, you are more likely to get a puncture. Due to the higher pressure, the tire is unable to give way. This makes it easy for a puncture to occur. You can demonstrate this by trying to pop and semi-inflated balloon and a fully inflated balloon. The fully inflated balloon will pop long before the semi-inflated balloon does.

Check Tire Manufacturer Guidelines
Firstly, make sure you become familiar with the listed specifications for your tires. Each product comes with a set of manufacturer guidelines for you to follow. This guide often includes the appropriate PSI measurement and a range that you should try to stay within. Taking note of this number for each individual tire will let you know exactly what value youre aiming for during maintenance.
Tips For Checking Tire Pressure
As a general rule, aim to check your tire pressure every two weeks and every time you set off for a long trip or are carrying a heavy load.
- Make sure your tires are cold.Youll get a more accurate reading if you check the pressure first thing in the morning when they havent been used or havent been in the direct sunlight for too long.
- Always use the handbook. When in doubt, refer to the vehicles manufacturers handbook. It will specify the minimum amount of air pressure needed in cold tires to support your vehicle.
- Use a reliable gauge and air compressor. You can buy one from an auto store or use one free of charge at a petrol station.
- Check the pressure properly. Place the gauge onto the valve stem and press down firmly until the hissing sound of air escaping stops. The gauge will show a reading of the pressure, make sure it matches the manufacturers recommendation. If its too high, push the valve to let out some air. If the air pressure is too low, attach the air compressor to the valve and fill the tire until it reaches the recommended level.

How To Find The Right Tire Pressure
You can find the right pressure for your tire on the sidewall of your tire below the manufacturers label. You might see Maximum Pressure 35 pounds per square inch. This number indicates how much inflation pressures your tires can carry at max.
However, it is often recommended not to fill up the tires to the max because it can decrease the life of your cars tires, and it can also jeopardize the handling. If the breaking threshold is increased which the tire pressure is at max, accidents could also take place.
Is 36 Psi Too High
Higher pressure generally is not dangerous, as long as you stay well below the maximum inflation pressure. That number is listed on each sidewall, and is much higher than your recommended tire pressure of 33 psi, Gary. So, in your case, Id recommend that you put 35 or 36 psi in the tires and just leave it there.

What Effects Car Tire Psi Pressure
The main factor that will impact your tire pressure is the ambient temperature outside. As the air outside decreases in temperature, the air molecules inside of your tires begin to slow down. When this happens the tire pressure inside of the tire will begin to slowly fall because of the decreased movement of the air molecules.
That is why its most common to see your tire pressure light on days where the temperature decreased significantly. You may also notice this happening if you park outside instead of in a temperature-controlled garage.
