Nissan Altima 2015 Tires Size

Okay, so you're looking for information on the right tire size for your 2015 Nissan Altima? You've come to the right place. As a service advisor, I help customers with this all the time, and it's crucial to get the right fit for safety, performance, and even fuel efficiency. Let's break down what you need to know.

Understanding the Correct Tire Size for Your 2015 Altima

The first thing to understand is that the 2015 Nissan Altima came with a few different tire size options, depending on the trim level. The base models typically had one size, while the higher trims might have slightly different ones. Knowing your trim level can help narrow things down, but the *absolute* best way to find the correct size is to check a few places:

The Sticker Inside Your Driver's Side Door: This is the gold standard. There's a sticker (often white or yellow) on the door jamb that lists the original tire size, the recommended tire pressure, and other important vehicle information. This is your most reliable source.
Your Owner's Manual: The owner's manual will also list the recommended tire sizes for your specific model year and trim.
The Sidewall of Your Existing Tires: If you still have the original tires (or tires that you know are the correct size), you can simply read the size code right off the sidewall. This code will look something like "215/60R16" or "235/45R18."

Let's decode what that size code actually means. Take, for example, "215/60R16":

215: This is the tire width in millimeters. In this case, the tire is 215 millimeters wide.
60: This is the aspect ratio. It represents the height of the tire sidewall as a percentage of the tire width. So, in this case, the sidewall height is 60% of 215 mm.
R: This indicates that the tire is a radial tire. Almost all modern passenger vehicles use radial tires.
16: This is the wheel diameter in inches. This tire is designed to fit a 16-inch wheel.

Using the correct tire size is crucial for a few reasons:

Safety: Incorrect tire sizes can affect your vehicle's handling, braking, and stability, especially in wet or snowy conditions.
Accuracy of Speedometer and Odometer: Tire size directly impacts the rolling circumference of the tire. If you use a tire size significantly different from the original, your speedometer and odometer readings will be inaccurate.
Proper Fitment: Using the wrong size tire can cause rubbing against the wheel wells or suspension components. It can also negatively impact your anti-lock braking system (ABS) and electronic stability control (ESC) systems.

Common Problems and Solutions Related to Tire Size on a 2015 Altima

Now, let's look at some specific problems you might be facing and how to solve them:

Problem: Can't Find the Original Tire Size Listed

Solution: As mentioned earlier, double-check the door jamb sticker and owner's manual. If those are missing or illegible, you can contact a Nissan dealership and provide them with your vehicle's VIN (Vehicle Identification Number). They should be able to look up the original tire size specifications for your Altima.

Problem: Tires are Rubbing Against the Wheel Wells

Solution: This almost always indicates that you're using the wrong size tire. The most common cause is that the tires are too wide or have too large of a diameter. The immediate solution is to replace the tires with the correct size. If you've recently installed aftermarket wheels, they might have an incorrect offset. Wheel offset affects how the wheel sits within the wheel well. If the offset is too far inwards, it can cause the tires to rub on the suspension components. Consult with a reputable tire and wheel shop to determine the correct offset for your vehicle. Ignoring tire rubbing can lead to serious damage to your tires, suspension, and body panels.

Problem: Speedometer is Inaccurate After Changing Tires

Solution: This usually happens when the replacement tires have a significantly different rolling circumference than the original tires. The solution is to either replace the tires with the correct size or have your speedometer recalibrated. Speedometer recalibration is typically done by a mechanic using specialized diagnostic equipment. The cost can range from $75 to $200 depending on the shop and the complexity of the recalibration.

Problem: Want to Change Tire Sizes for a Different Look or Performance

Solution: While it's possible to deviate slightly from the original tire size, it's crucial to do so carefully and with expert advice. Changing tire sizes can affect handling, ride quality, and fuel efficiency. Consult with a tire specialist to discuss your goals and determine if there are any alternative tire sizes that would be suitable for your vehicle without causing any problems. Be prepared to potentially need different wheels to accommodate a significantly different tire size. Never choose a tire size that doesn't have adequate load rating for your vehicle. Overloaded tires are a major safety hazard.

Problem: Tire Pressure Monitoring System (TPMS) Light is On After Changing Tires

Solution: This could be due to a few reasons. First, make sure that all of your tires are inflated to the correct pressure (listed on the door jamb sticker). If the TPMS light remains on, it could be that the TPMS sensors in your wheels need to be reset or recalibrated. Some TPMS systems automatically relearn after a few miles of driving, while others require a manual reset using a TPMS scan tool. If the sensors are old, they may also need to be replaced. TPMS sensors typically last for 5-7 years. A TPMS reset at a tire shop typically costs between $25 and $75. Replacing a TPMS sensor can range from $50 to $150 per sensor, including labor.

Tools and Costs

Here are some common tools and approximate costs associated with tire-related issues:

Tire Pressure Gauge: Essential for checking tire pressure. Costs range from $5 to $30.
Torque Wrench: Important for tightening lug nuts to the correct torque specification. Costs range from $30 to $100.
Jack and Jack Stands: Necessary for lifting the vehicle to change tires. A good quality jack and jack stands will cost between $50 and $150.
Lug Wrench: Used to loosen and tighten lug nuts. Typically comes with the vehicle, but aftermarket lug wrenches are available for around $20.
Tire Repair Kit: For repairing minor punctures. Costs around $15 to $30.
Professional Tire Installation: Expect to pay around $15 to $30 per tire for professional installation, including balancing.
Wheel Alignment: A wheel alignment is recommended after changing tires or experiencing any handling issues. Costs range from $75 to $150.

Tips for Choosing the Right Tires

Beyond the correct size, here are some things to consider when choosing new tires for your 2015 Altima:

Tire Type: Consider your driving conditions and needs. All-season tires are a good choice for most drivers, offering a balance of performance in various weather conditions. Performance tires offer better grip and handling but may wear out faster and be less suitable for winter driving. Winter tires are designed for optimal performance in snow and ice.
Tread Pattern: The tread pattern affects traction, noise, and wear. Look for a tread pattern that suits your driving style and the conditions you typically encounter.
Tire Brand: Choose a reputable tire brand known for quality and performance. Some popular brands include Michelin, Bridgestone, Goodyear, Pirelli, and Continental.
Tire Ratings: Check the tire ratings for treadwear, traction, and temperature resistance. Higher ratings generally indicate better performance and durability.
Read Reviews: Before making a purchase, read online reviews from other Altima owners to see what they have to say about different tire brands and models.

Final Thoughts

Choosing the right tire size for your 2015 Nissan Altima is essential for safety, performance, and longevity. Always refer to the sticker on your driver's side door jamb or your owner's manual for the correct size specifications. If you're unsure or have any questions, consult with a qualified tire professional. Taking the time to do your research and choose the right tires will ensure a safe and enjoyable driving experience.

Remember to regularly check your tire pressure and inspect your tires for wear and damage. Proper tire maintenance is crucial for maximizing tire life and ensuring your safety on the road. And never drive on tires that are excessively worn or damaged.
