Tires with low pressure are more likely to blow out—a main cause of car accidents.
As part of Park & Jet's Pay It Forward Initiative , we're running around town asking local Calgary businesses what they think! We spoke to The Gear Shop in Inglewood to find out more about tire pressure!
Question 1: What is the correct tire pressure for a passenger vehicle such as a car? A truck?
Answer 1: The correct tire pressure is linked to the weight of the vehicle. Car tire pressures are around 32 psi (2.2 bar). Four-wheel-drive vehicles and small truck tires need around 35 psi (2.4 bar) with full-size truck tires requiring between 40-60 psi (2.8-4.1 bar). Do you know what is recommended for your vehicle?
Tip: Find your vehicle's recommended tire pressure in your car manual. Often, it is also written on a sticker somewhere on the frame of the driver's door.
Question 2: Would a higher than recommended tire pressure save you fuel?
Answer 2: Yes. Inflating passenger car tires to between 40-60 psi could save money at the gas pumps. HOWEVER, over-inflating tires wears out their centres. This means that tires will need to be replaced more frequently. You might end up spending your fuel savings on new tires. Probably best to stick to the recommended tire pressures for your vehicle.
Question 3: Is nitrogen better for tires than air?
Answer 3: Not really. It is true that nitrogen might not leak as easily, but nitrogen costs money whereas air is free. Also, cold winter temperatures make nitrogen denser, causing tires to become flatter when it is very cold outside.
Question 4: How often should you check your tire pressures?
Answer 4: Technically, once a month or once a season should be enough because tires in good condition don't lose air very quickly. However, note the phrase 'in good condition.' You could be riding around with a nail in your tire, losing air slowly and not know it, or have some other tire issue, causing dangerous low pressure. To be on the safe side, check your tire pressures each time you fill your gas tank.
If you didn't do well, now you know the essentials.

“I was taking about my upcoming trip on my show and I mentioned I was flying out of Calgary. I then asked my listeners do they normally stay and park at a hotel, use Airport parking or off site? Several called to say I should try Park & Jet! I’m looking forward to using your service. Thanks!” -Tank Montana - Breakfast Show Host Sunny 94FM
