What number should your tires be on?
As a car owner, maintaining the correct tire pressure is one of the simplest yet most important aspects of vehicle care. Proper tire pressure ensures safety, improves fuel efficiency, and extends the life of your tires. But what exactly does "the right number" mean when it comes to your tires? Let’s dive into the details to help you understand tire pressure and how to find the correct number for your vehicle.
Understanding Tire Pressure Numbers
Tire pressure is measured in pounds per square inch (PSI). The correct PSI for your tires is determined by the vehicle manufacturer and is based on factors such as the weight of the car, its suspension system, and the type of tires it uses. Driving with the wrong tire pressure can lead to uneven tire wear, reduced fuel efficiency, and even dangerous blowouts.
Where to Find the Correct Tire Pressure
To ensure your tires are inflated to the correct PSI, follow these steps:
- Check the Driver’s Side Door Frame: Most vehicles have a sticker located on the driver’s side door frame or inside the glove box. This sticker lists the recommended tire pressure for both the front and rear tires.
- Consult the Owner’s Manual: If you can’t find the sticker, your vehicle’s owner’s manual will also provide the recommended PSI.
- Do Not Rely on the Tire Sidewall: The number printed on the sidewall of your tire is the maximum PSI the tire can handle, not the recommended pressure for your vehicle.
How to Check and Adjust Tire Pressure
Maintaining the correct tire pressure is easy with the right tools and a little know-how. Here’s how you can do it:
- Use a Tire Pressure Gauge: Purchase a reliable tire pressure gauge to check your tire pressure regularly. Digital gauges are particularly easy to use and provide accurate readings.
- Check When Tires Are Cold: Tire pressure increases as the tires heat up from driving. For the most accurate reading, check your tire pressure when the car has been parked for a few hours or overnight.
- Inflate or Deflate as Needed: If the pressure is too low, use an air compressor to add air until you reach the recommended PSI. If it’s too high, release air by pressing the valve stem until the pressure is correct.
Why Proper Tire Pressure Matters
Driving with the correct tire pressure offers several benefits:
- Improved Safety: Properly inflated tires provide better traction and handling, reducing the risk of accidents.
- Better Fuel Efficiency: Underinflated tires create more rolling resistance, which can decrease your gas mileage.
- Extended Tire Life: Correct tire pressure prevents uneven wear, helping your tires last longer and saving you money in the long run.
Final Thoughts
Keeping your tires at the correct PSI is a simple yet crucial part of vehicle maintenance. Make it a habit to check your tire pressure at least once a month and before long road trips.

Frequently Asked Questions
What number should my tire pressure be on?
Most passenger cars will recommend 32 to 35 psi in the tires when they're cold. The reason you check them cold is that as tires roll along the road, friction between them and the road generates heat, increasing tire pressure.
Is a tire tread of 7 good?
Is 7/32, 8/32, 9/32, 10/32 Good Depth? In most cases, new tires come with a 10/32 to 12/32 tread depth, and with driving, that parameter decreases until it drops below 6/32 or 5/32, which means it's time to consider replacing your tires.
What level should your tires be at?
Running your tires at the correct pressure is important because it keeps you safe, cuts down your gas bill, and makes your tires last longer. Each vehicle has its own specifications for tire pressure, but most fall between 28 and 36 PSI (pounds per square inch).
What is a good tire treadwear number?
High Treadwear Applications (500 and More)
High longevity tires, mainly for commercial vehicles and certain passenger cars, tend to be cheap, low grip, and incredibly long-lasting. These tires start at a treadwear rating of 500 and can rise to 700 and higher.
Is 7 tire pressure bad?
Remember, anything lower than 20 PSI is considered a flat tire. Consistently monitor your tire pressure and make sure to regularly fill your tires with air to keep them in that ideal 32 to 35 PSI sweet spot, for better safety and mileage.
Is 28 tire pressure too low?
Most passenger car tires require 32 psi to 35 psi, so, yes, 28 psi is too low for tire pressure. Make sure each tire is filled with the proper pressure and that the stem caps are put back on securely afterwards.
Which tire is taller 60 or 70?
If a tire has an aspect ratio of 70, it means the tire's height is 70% of its width. Lower aspect ratio tires, such as a 60 series, generally offer vehicle handling performance advantages over higher aspect ratio tires, such as a 75 series.
Is a 4 on a tire bad?
Low tire tread: Many mechanics recommend replacement when your vehicle reaches between 3/32 and 4/32 of an inch. This is especially true if you live in an area with severe climates to prevent hydroplaning and other inclement weather risks. Good tread levels: New tires often have 11/32 of an inch of tread.
Is 40 PSI too high for tires?
Tire pressure increases when the tires are used, and for this reason, following the vehicle and tire brands' recommendation is crucial. Typically, if the recommended pressure levels are 35, then the tires should not use more than 40 psi. More than that will result in the before mentioned problems.
What number should your tire tread be?
Good tire tread depth will be 6/32 or deeper. If the depth is 4/32, you should start thinking of replacing your tires and getting new ones. 2/32 or less means that you should change your tires ASAP. The amount of tire tread can affect your stopping distance, making a drive in wet or snowy conditions more dangerous.
