Chevrolet Cruz Tire Monitoring System

I can guarantee that anybody owning a car, even enthusiasts, can’t stand changing a flat tire. Regardless if it’s an inconvenience or not, changing a flat tire majority of the is downright dangerous. Not to mention, spare tires can weight as much as 60lbs, which in this time of getting the most MPGs out of your car, can make quite the difference.

To reduce weight and increase safety, nearly ever manufacturer has replaced a full-size spare with a space-saving donut. And some, like Chevrolet, have decided to eliminate it all together, which is what they did with the new 2011 Chevrolet Cruze.

Instead of a spare tire of any sort, Chevrolet equips all of their Cruze models with an on-board tire inflator kit. The result is a 26 lb weight reduction from the lack of a spare and jack. Again, that doesn’t sound like much but GM is doing their best to hyper-mile their cars by eliminating any excess where possible and every little bit helps.

The result is a boost to an EPA rated 42 mpg on the highway for the 2011 Chevrolet Cruze ECO, giving it the title as the best highway mileage of any non-hybrid, gasoline-powered compact available in the US.

“Getting rid of something as important as the spare tire wasn’t a decision we made lightly,” said Terry Connolly, GM director of Tire and Wheel Systems. “The universal implementation of tire pressure monitoring systems over the past five years has significantly reduced the likelihood that a flat tire will leave you stranded by the side of the road.”

Additionally, a Tire Pressure Monitoring system also warns the driver when pressure is low to avoid tire damage. When used, the tire-inflator kit can be plugged into the car’s 12-volt outlet and can reinflate the tire without any additional equipment. Upon filling the tire with air, the kit automatically injects tire sealant that’s capable of filling holes up to ¼ of an inch in diameter in the tread. The whole process can be completed in a manner of minutes.If the tire is irreparable with the inflator kit, drivers can use the Cruze’s OnStar system to request roadside assistance.

“The Cruze engineering team equipped the Eco with industry-leading low rolling-resistance tires. Ensuring that they stay properly inflated will help drivers get the full benefit of this lower fuel consumption,” said Connolly. “Tire pressure actually changes about one pound per square inch for every 10 degrees of ambient temperature change. Keeping your tires at the recommended pressure year round means drivers won’t have to fill the fuel tank quite as often.”

    Now that’s what I call getting desperate to increase MPG……..don’t you?
    If ya read in between the lines it’s not about saving MPG’s it’s about saving money on the bottom line as to what it cost to produce these vehicles by NOT equipping them with a spare tire.
    GM is back to it old tricks about deceiving the public again. No surprises there.

    “Chevrolet Cruze gets rid of spare tire to boost MPGs”

    Do you REALLY expect the GP(general public)to believe this?
    I for one ain’t buying it. This has more to do with the bottom line…….more profit for GM
    by eliminating the spare time. This has nothing to do with increasing MPGs or safety.
    I would have more respect for GM if they made a statement to GP to loose weight equivalent to what the spare tire weight is then to try this deception tactic.

    To The Author,
    Most Chevy Cruze’s do come with a spare tire, it is actually an option to eliminate the tire for the inflator kit.  You can mostly see this on the Cruze Eco edition, as you see in the photo, that particular aluminum rim is from the Eco edition.  Signed, GM technician.

    I NEED a spare, give me my spare!

    I didn’t research the car for this when I was looking to buy a pre-owned car. Not having a spare tire is the most stupid thing I’ve ever heard of. I don’t care about increasing the MPG’s, especially when it’s not going to make that much of a difference. It’s more of a safety issue. Not everyone can pay for Onstar to get roadside assistance and if you’re traveling on a stretch of highway and you can;t reinflate then it’s going to cost a lot to get towed. I shouldve know better than to buy GM.

    I bought a pre-owned Chevy Cruze and never bothered to look under the wheel covering in the trunk until I had a flat tire. Lo and behold, no tire, no jack, no nothing. My brother had to jack the car up with his jack, remove the tire and wheel, go to the tire store and buy a new tire and have it mounted on the rim, bring it back and put it on the car. Talk about a shock. Not even a lousy can of Fix-it-Flat!
