What Size Rims Will Fit On A Nissan Altima

Upgrading or replacing the wheels on your Nissan Altima can significantly alter its appearance, handling, and even fuel economy. However, it's not as simple as picking out the flashiest rims you can find. Understanding the nuances of wheel sizing and fitment is crucial to avoid rubbing, suspension damage, or compromised safety. This guide will provide an in-depth look at determining the correct rim size for your Nissan Altima, covering the key specifications and considerations.

Understanding Wheel Specifications

Before diving into Altima-specific recommendations, let's define the core specifications that dictate wheel fitment. These parameters are usually stamped on the inside or outside of the wheel itself.

Wheel Diameter

The wheel diameter is the distance across the wheel measured at the bead seat, where the tire sits. It's measured in inches (e.g., 17", 18", 19"). Changing the wheel diameter requires corresponding adjustments to the tire size to maintain the overall rolling diameter, which is essential for accurate speedometer readings and proper ABS function.

Wheel Width

Wheel width refers to the distance between the inner and outer flanges of the wheel, also measured in inches. A wider wheel can accommodate a wider tire, potentially improving grip. However, excessive width can lead to rubbing against the suspension components or fender wells.

Bolt Pattern (PCD)

The bolt pattern, also known as Pitch Circle Diameter (PCD), specifies the number and spacing of the lug holes. It's expressed as two numbers, such as 5x114.3. The first number indicates the number of lug holes (in this case, 5), and the second number represents the diameter of the circle (in millimeters) on which the lug holes are centered. Using wheels with an incorrect bolt pattern is extremely dangerous and can lead to wheel detachment. The Nissan Altima commonly uses a 5x114.3mm bolt pattern, but it's always best to verify this for your specific year and model.

Offset (ET)

Offset (ET) is the distance in millimeters between the wheel's mounting surface and its center line. A positive offset means the mounting surface is closer to the outside of the wheel, while a negative offset places it closer to the inside. Offset significantly impacts how the wheel sits within the wheel well. A lower offset will push the wheel outwards, potentially improving the stance but increasing the risk of rubbing. A higher offset will pull the wheel inwards, which might create clearance issues with suspension components.

Center Bore

The center bore is the diameter of the hole in the center of the wheel that centers it on the vehicle's hub. If the center bore of the wheel is smaller than the hub diameter, the wheel will not fit. If the center bore is larger, hub-centric rings are often used to ensure proper centering and prevent vibrations. Using lug-centric wheels without hub-centric rings can place undue stress on the lug studs.

Nissan Altima Rim Size Considerations

Now, let's focus on the Nissan Altima. The optimal rim size depends on the generation of your Altima, your desired aesthetics, and your driving style. Here's a general guideline:

• Factory Sizes: Altimas typically come with wheels ranging from 16" to 19" in diameter, depending on the trim level and year. Checking the sticker on your driver's side doorjamb will reveal the factory-recommended tire and wheel sizes. This information provides a safe starting point.
• Upgrading Diameter: Increasing the wheel diameter generally improves handling and appearance. However, you must reduce the tire sidewall height proportionally to maintain a similar overall rolling diameter. For example, going from a 17" wheel to an 18" wheel might require switching from a 215/55R17 tire to a 225/45R18 tire. Use a tire size calculator (easily found online) to ensure the new tire is within 3% of the original rolling diameter.

  Exceeding this tolerance can affect speedometer accuracy, ABS performance, and even transmission shift points.

• Wheel Width and Offset: This is where careful consideration is most important. A wider wheel allows for a wider tire, which can improve grip. However, exceeding the available space in the wheel well will result in rubbing. The optimal offset depends on the wheel width and the amount of clearance you have. Aggressive offsets can significantly alter the car's handling and appearance, but they require careful measurement and potentially modifications like fender rolling or using wheel spacers (with caution!).

Specific Generation Considerations:

It's crucial to understand the specific generation of your Altima, as wheel wells and suspension designs change over time. Here's a general overview, but *always double-check specifications and fitment information specific to your exact year and model*:

• 1st Generation (1993-1997): Generally limited to smaller wheel sizes (14" - 16"). Clearance is tighter compared to later generations.
• 2nd Generation (1998-2001): Similar to the 1st generation in terms of wheel size limitations. 15"-17" are common upgrade sizes.
• 3rd Generation (2002-2006): 16" - 18" wheels are typically safe. More room for wider tires compared to previous generations. Offset plays a crucial role in avoiding rubbing.
• 4th Generation (2007-2012): 16" - 19" wheels are common. A wider range of offsets can be accommodated, but careful measurement is still necessary. This generation benefits from research in online Altima forums where owners share fitment experiences.
• 5th Generation (2013-2018): Similar to the 4th generation, with 17"-19" being common upgrades. Aggressive offsets might require fender modifications.
• 6th Generation (2019-Present): 17"-19" wheels are common. The available space in the wheel wells can be tested cautiously with aftermarket wheels to ensure clearance.

Essential Tools and Resources

Determining the right wheel size involves more than just guesswork. Here are some tools and resources to help:

• Tire Size Calculator: Online tools that compare tire sizes and calculate the difference in rolling diameter. Essential for maintaining speedometer accuracy.
• Offset Calculator: Online tools that help determine the effect of changing wheel offset on wheel position.
• Measuring Tools: A ruler, measuring tape, and a straight edge are invaluable for measuring clearances within the wheel well.
• Online Forums: Altima-specific online forums are a treasure trove of information. Owners often share their wheel and tire setups, including details about offsets, tire sizes, and any modifications they had to make.
• Professional Consultation: Consulting with a reputable tire and wheel shop is highly recommended. They have the experience and tools to accurately assess your vehicle and recommend appropriate wheel sizes.

Practical Steps for Determining Fitment

1. Determine Stock Specifications: Find the factory wheel and tire sizes listed on the doorjamb sticker or in the owner's manual.
2. Research Offset Range: Use online resources and forums to identify the typical offset range that works for your Altima generation and desired wheel width.
3. Measure Existing Clearances: With your current wheels installed, measure the distance between the tire and the fender lip, as well as the distance between the tire and the suspension components. This will give you an idea of how much room you have to work with.
4. Use Calculators: Plug your desired wheel width and offset into an offset calculator to see how the new wheel will sit compared to your existing wheel.
5. Consider Tire Size: Select a tire size that matches your desired wheel diameter and width, while maintaining a rolling diameter close to the original.
6. Test Fit (If Possible): If possible, test fit a wheel and tire combination before purchasing. Some tire shops will allow you to temporarily mount a wheel to check for clearance issues.

Potential Problems and Solutions

Even with careful planning, you might encounter issues during the wheel upgrade process. Here are some common problems and their solutions:

• Rubbing: If the tires rub against the fender wells, you have several options:
  • Roll the Fenders: A fender roller tool can be used to gently bend the inner fender lip outwards, creating more clearance.
  • Choose a Smaller Tire: A slightly narrower tire or a tire with a shorter sidewall can provide more clearance.
  • Increase Offset: Wheels with higher offset will pull the wheel inwards and could solve rubbing on the outside of the fender.
  • Install Stiffer Suspension: If rubbing only occurs during hard cornering or bumps, stiffer springs or shocks can reduce suspension travel and prevent rubbing.
• Clearance Issues with Suspension: If the wheel or tire rubs against the suspension components, you may need to:
  • Use Wheel Spacers (with caution): Wheel spacers push the wheel outwards, creating more clearance. However, they also increase stress on the wheel bearings and studs. Use high-quality spacers from a reputable brand and ensure they are properly torqued. Do not use excessively thick spacers.
  • Choose a Different Offset: Higher offset would move the wheel further into the wheel well and possibly away from suspension components.
• Vibrations: Vibrations can be caused by:
  • Improper Wheel Balancing: Ensure the wheels are properly balanced by a professional.
  • Incorrect Center Bore: Use hub-centric rings to ensure the wheel is properly centered on the hub.
  • Damaged Wheels or Tires: Inspect the wheels and tires for any signs of damage.
