The Right Spare Tire Kit Engineered Specifically Your 2019-2021 Mercedes GLB

We guarantee the Modern Spare Spare Tire kits to be the highest quality and best choice for your Mercedes GLB.  Here is why:

“Run-Flat” Tires-

Like many cars, Mercedes models now come equipped with “run-flat” type tires. Run-flats are the carmaker’s choice as a spare tire alternative. So why are so many unahppy with this choice?

  • Many Mercedes owners find run-flat tires to have poor ride and handling quality.
  • Besides having wear ratings half of a normal tire’s lifespan, they are very expensive to replace.
  • Run-flats perform their intended function in getting you to a repair shop without air pressure, but most often need full replacement if used without air pressure.

The Modern Spare solution allows you to replace your run-flat tires with more affordable and better performing conventional tires while still enjoying peace of mind as you travel. You can choose the best performing, best wearing and best-priced tire for your money without fear of being stuck on a roadside. 

Our Design-

To make your Modern Spare Kit incredibly simple to use, we designed an aluminum alloy wheel that is significantly lighter and more capable than a conventional steel counterpart.  As a result, our spare wheel/tire combination is easier to handle. The low weight improves your GLB’s performance and fuel economy when compared to a heavier full-sized spare. Also, to maintain excellent standards of quality, our alloy wheel meets or exceeds all the latest DOT highway safety standards. In addition, each spare wheel is equipped with a durable space-saving tire capable of traveling at highway speeds up to 81mph. The improved tire allows you to travel the needed distance to a repair shop you trust.

Better Tools-

To make our Spare Tire Kit better for your Mercedes, we considered the frustrations that come with typical spare tire tools.  As an example, most scissor jacks are difficult to use and do not provide the needed leverage to easily lift your car. We solved this problem by developing a custom low-profile scissor jack with a unique ratcheting handle mechanism.  This handle provides the required leverage to easily lift your car and lower it safely.  We have carefully designed our jack to lift your car properly at the designated lift points.

If you find a stubborn or overtightened lug nut, our Modern Spare telescoping lug wrench provides nearly two feet of leverage. You’ll be able to easily remove and retighten your lug nuts to quickly get back on the road.

As a forethought, we included a full-size, thick plastic tire bag.  Transporting a full-size flat tire and wheel can be messy. Therefore, placing the large plastic tire bag over the failed tire will help protect your car’s interior.

Our Goal-

By now, you’re aware that your GLB is missing a spare tire. Mercedes, like many carmakers are not providing this important lifesaver. Modern Spare wants to be the best manufacturer and provider of complete spare tire kits hands-down. We have approached our Modern Spare designs from every angle. This ensures that our customers have the best user experience possible with the best product possible. Please reach out to any of our helpful staff for questions and assistance.
