Time to check your tires

Road trip season is upon us and as the weather warms up more people hit the highway for a getaway.

Drivers might think their car tires are fine just by looking at them, but those tires could be under-inflated by as much as 20 per cent and that could cause sloppy handling and poor fuel economy at best, and the possibility of blowouts at worst.

“After a long winter, we see a lot of drivers coming in to our stores with tires that are significantly under-inflated because tires can be deceptive,” said Kyle Lewarne, zone manager, Kal Tire. “Many drivers don’t regularly check their vehicle’s tire pressure and it’s impossible to tell just by looking at a tire if there’s a slow leak.”

In a study referenced by Transport Canada, “50 per cent of vehicles on the road in Canada have at least one tire that is either over or under-inflated by more than 10 per cent. In fact, 10 per cent of all vehicles surveyed had at least one tire under-inflated by 20 per cent.”

What are drivers risking when their vehicles have under-inflated tires?

  • Compromised handling. Tires can’t respond as quickly or accurately. “Even if you were driving 50 kilometres/hour and your tire pressure was down only about 5 PSI (typical recommended pressure on a passenger car is 35 PSI), your tires would begin to curl under and be noticeably delayed in how they respond to cornering and swerving,” says Lewarne.
  • Increased risk of blowouts and crashes. The sides of under-inflated tires bend, flex and build up dangerous friction and heat that can cause tires to ‘blow out.’
  • Shortened tire life. Too much flexing and tire overloading (especially with extra luggage or camping gear), while operating a vehicle with just one tire under-inflated by 8 PSI can reduce tire life by 15,000 km.
  • Increased fuel consumption. Because it takes more energy for the vehicle to roll, maintaining tire pressure could save you almost two weeks of fuel every year5.
  • Increased susceptibility to pothole damage. Air pressure protects both the tire and wheel from direct pothole impact. Less air means a harder impact, which can also damage a vehicle’s suspension components.

Kal Tire encourages drivers to be proactive about checking and maintaining tire pressure, and making it a habit not just when traveling, but year-round.

After determining the manufacturer’s recommended pressure (often indicated on a door jam sticker or the owner’s manual), simply check pressure with a reliable gauge and at the right time (when tires haven’t been driven for at least a few hours), and inflate, preferably at a tire service centre.

“We recommend checking at the outset of every trip, but it’s also good to get in the habit of checking once a month or even every time you fill up with gas. It just takes a few minutes and you’re going to be rewarded with tire life and performance, and, of course, safety,” said Lewarne.
