It's no secret that appropriate tires can make all the difference for a smooth ride in your INFINITI. But, what's more: the way your tires are attached is critically important, too. Wheel lug nuts are meant to securely hold your tires to your INFINITI's wheel assembly and axles. Sounds pretty straightforward, right? Not so fast. These lug nuts must be installed and adjusted to a precise torque level to prevent premature wear and tear to your wheels and braking system.

Each tiny (but powerful!) Wheel Lug Nut on your INFINITI is designed to hold and distribute the weight of each tire and keep it in place so it can roll efficiently while your vehicle is in motion.

If a Wheel Lug Nut is missing or tightened incorrectly, you might be slowly (and unknowingly) causing damage to one or more tires or your INFINITI's metal wheels. A lug nut that's too loose could result in a shaky roll in your tires (and low fuel efficiency), and one that's too tight might jam your tire into a nearby brake rotor, leading to a compromised or warped rotor and a domino effect of costly repairs. If you lose a Wheel Lug Nut during a severe blowout or a tire-related accident, you may not be able to attach your INFINITI's spare tire without that piece. With that in mind, it's probably smart to stash an additional Wheel Lug Nut or two in an emergency toolkit just in case you have a damaged or missing lug nut.

You might be able to install a replacement Wheel Lug Nut at home, but remember that every lug nut must be adjusted to a precise torque with a specialty tool called a torque wrench. It's vital that you have the right tools and intermediate knowledge of auto parts before you attempt to replace your Wheel Lug Nut. Review the owner's manual for your INFINITI to determine the ideal torque level for your model.
