Tire Pressure Check
Don’t you love driving on newly inflated tires? Doesn’t it feel like your car just works better? It’s not in your head. Properly inflated tires provide better shock absorption, traction, braking, and steering response. It’s a difference you can feel.
But maintaining proper tire pressure gives you much more than the feeling of a comfortable, responsive car. It may just be your easiest way to maximize the safety and performance of your vehicle while minimizing its cost of ownership. Here’s how:
- Safety: An under-inflated tire faces an increased blowout risk. Under low pressure, more of your tire comes into contact with the road, generating extra friction and heat. And the flatter shape of an under-inflated tire places extra strain on its rubber and metal components. A properly inflated tire is free of these particular stresses.
- Tire Longevity: Too much or too little tire pressure shortens tire life by causing uneven tread wear (not to mention wear on parts of the tire not designed for road contact). Proper tire pressure helps you avoid premature tire replacement.
- Fuel Efficiency: Proper tire pressure can boost fuel efficiency by as much as 3%. On average, drivers can save 2 cents a gallon, which adds up to $240 over 12,000 miles.1
That’s why every Midas Closer Look Vehicle Check™2 includes a tire pressure check.
A sticker showing your recommended tire pressure is usually found in the driver’s door jamb (newer vehicles) or in the glove compartment. Your proper tire pressure will also be listed in your vehicle’s owner’s manual. Pay attention to the details: front, rear, and spare tires usually have different pressure targets, and some stickers provide hot and cold pressure targets. (In this context, “hot” refers to the temperature of the tire, not the weather. If you’ve been driving on it, the tire is hot.)
Never rely on any pressure markings you see on the tire itself -- this number represents the maximum pressure the tire can withstand.
What should my tire pressure be in cold weather?
Your tire pressure in cold weather should be monitored with extra vigilance. Cold weather itself decreases tire pressure by condensing the air inside your tires. Expect your tires to lose 1 PSI for every 10 degrees the temperature falls -- and vice versa. Your vehicle’s sticker (in the driver’s door jamb or glove box) or your owner’s manual will specify your recommended tire pressure.
