2013 Nissan Altima Lug Nut Size

Alright, let's talk about lug nuts on your 2013 Nissan Altima. It might seem like a simple thing, but having the right information about your lug nuts is crucial for safe and proper wheel maintenance. We've seen it all here at the shop, from stripped threads to improperly torqued wheels, and we want to help you avoid those headaches.

The Problem: Identifying the Correct Lug Nut Size for your 2013 Altima

The most common issue we see is people either needing to replace a damaged or missing lug nut, or they're looking to upgrade to a different style (like spline drive lug nuts for aftermarket wheels). The problem arises when they don't know the exact specifications. Buying the wrong size can lead to serious problems:

Damage to the wheel studs: Using the wrong thread size can strip the threads on your wheel studs, requiring costly repairs. Replacing wheel studs is a much bigger job than replacing a lug nut!
Loose wheels: If the lug nut doesn't seat properly, it can loosen over time, leading to dangerous vibrations and potentially even wheel separation.
Difficulty tightening: An incorrect size might seem to tighten, but it won't achieve the proper torque, increasing the risk of loosening.

So, what's the magic number? The correct lug nut size for a 2013 Nissan Altima is 12mm x 1.25. That means it's a 12mm diameter stud with a 1.25mm thread pitch. This applies to all trim levels of the 2013 Altima, including the S, SV, SL, and even the hybrid models.

Beyond the size, you'll also want to consider the lug nut type. The 2013 Altima uses a flanged lug nut, which means it has a built-in washer-like flange that distributes the clamping force evenly against the wheel. This is important for proper seating and preventing damage to the wheel.

The Solution: Finding and Replacing Lug Nuts Correctly

Now that you know the correct size, let's discuss how to find replacements and ensure they're installed properly.

Finding Replacement Lug Nuts

You have several options for sourcing replacement lug nuts:

Your Local Nissan Dealer: This is often the safest bet for getting the exact OEM (Original Equipment Manufacturer) lug nuts. They'll be a direct match and ensure proper fitment.
Auto Parts Stores (e.g., AutoZone, Advance Auto Parts, O'Reilly): These stores carry a wide variety of lug nuts, including aftermarket options. Just make sure to confirm the 12mm x 1.25 size and the flanged design before purchasing. Double-check the specifications on the packaging or ask a store associate for assistance.
Online Retailers (e.g., Amazon, eBay): Online retailers offer a huge selection and often competitive prices. However, be extra careful to verify the specifications and read reviews to ensure you're buying a quality product from a reputable seller. Look for brands you recognize and trust.

Important Tip: When purchasing lug nuts online, always filter by your vehicle's year, make, and model. This will help narrow down the options and increase the likelihood of finding the correct fit.

Replacing Lug Nuts: A Step-by-Step Guide

Replacing a lug nut is a relatively straightforward process, but safety should always be your top priority.

Gather Your Tools: You'll need the following:
- A lug wrench (ideally a 4-way lug wrench for better leverage)
- A torque wrench
- A jack and jack stands
- Wheel chocks
- (Optional) Penetrating oil (like WD-40 or PB Blaster) if the lug nut is seized.
Safety First: Park your Altima on a level surface, engage the parking brake, and place wheel chocks behind the wheels opposite the one you're working on.
Loosen the Lug Nuts: Before jacking up the car, use the lug wrench to loosen the lug nuts on the wheel you're removing. Don't remove them completely, just break them free. If a lug nut is particularly stubborn, try applying penetrating oil and letting it sit for a few minutes. Use your foot for added leverage on the lug wrench if needed.
Jack Up the Car: Consult your owner's manual for the correct jacking points on your Altima. Place the jack securely and lift the car until the tire is off the ground.
Support with Jack Stands: This is crucial! Never work under a car supported only by a jack. Place jack stands under the vehicle's frame near the jacking point. Lower the car onto the jack stands.
Remove the Wheel: Now, completely remove the loosened lug nuts and carefully pull the wheel off the hub.
Replace the Lug Nut(s): Thread the new lug nut onto the wheel stud by hand, ensuring it's properly aligned. Do this for all the lug nuts.
Reinstall the Wheel: Carefully align the wheel with the studs and push it onto the hub.
Hand-Tighten the Lug Nuts: Hand-tighten the lug nuts in a star pattern (opposite nuts) to ensure even pressure on the wheel.
Lower the Car: Raise the car slightly with the jack to remove the jack stands. Carefully lower the car to the ground.
Torque the Lug Nuts: This is the most important step! Use a torque wrench to tighten the lug nuts to the correct torque specification. For a 2013 Nissan Altima, the recommended torque is 83 ft-lbs (113 Nm). Again, tighten in a star pattern.
Double-Check: After driving a short distance (about 50-100 miles), re-torque the lug nuts to ensure they haven't loosened.

Important Notes:

Always use a torque wrench to ensure proper tightening. Overtightening can damage the studs and wheels, while undertightening can lead to loose wheels.
Tighten the lug nuts in a star pattern to evenly distribute the clamping force.
If you're unsure about any part of this process, it's always best to consult a professional mechanic.

Tools Needed

Lug wrench
Torque wrench (capable of measuring 83 ft-lbs)
Jack and jack stands
Wheel chocks
Socket (usually 19mm or 21mm) that fits your lug nuts. Verify before starting.
(Optional) Penetrating oil
Gloves

Estimated Repair Costs

If you prefer to have a professional handle the lug nut replacement, here's a general idea of what you can expect to pay:

Lug Nut Replacement (Single): $15 - $30 (including the cost of the lug nut)
Wheel Stud Replacement (If Needed): $80 - $200 per stud (depending on labor rates and part costs). This is significantly more expensive, so preventing damage by using the correct lug nuts is crucial.

These are just estimates, and the actual cost may vary depending on your location and the shop you choose. Always get a quote before authorizing any work.

Conclusion

Knowing the correct lug nut size for your 2013 Nissan Altima (12mm x 1.25 with a flanged design) is essential for safe and effective wheel maintenance. By following these steps and using the right tools, you can confidently replace your lug nuts and keep your Altima rolling smoothly. Remember, if you're ever unsure about any aspect of this process, don't hesitate to seek professional help. A little caution can go a long way in preventing costly repairs and ensuring your safety on the road. Happy driving!
