Specifications Of Oem Wheels For All Nissan 240sx Models

Finding the right wheels for your Nissan 240SX can significantly impact its performance, handling, and overall aesthetic. Original Equipment Manufacturer (OEM) wheels, those that came standard on the car from the factory, offer a reliable and often cost-effective option. This guide provides a comprehensive overview of the specifications of OEM wheels for all Nissan 240SX models, helping you make an informed decision whether you're restoring your classic or simply looking for a change.

Understanding Nissan 240SX Wheel Specifications

Before diving into specific models, let's define the key terms related to wheel specifications:

  • Diameter: The overall size of the wheel, measured in inches.
  • Width: The distance between the inside edges of the wheel's flanges, also measured in inches.
  • Bolt Pattern (PCD): The diameter of the circle formed by the wheel's bolt holes, and the number of bolts. For example, 5x114.3 means 5 bolts on a 114.3mm diameter circle.
  • Offset (ET): The distance, in millimeters, between the wheel's mounting surface and its centerline. A positive offset means the mounting surface is closer to the outside of the wheel, while a negative offset means it's closer to the inside.
  • Center Bore: The diameter of the hole in the center of the wheel that fits over the hub of the car. Measured in millimeters.

Understanding these specifications is crucial to ensure proper fitment and avoid issues like wheel rubbing or stress on the suspension components. Always double-check the specifications before purchasing any wheels.

OEM Wheel Specifications by 240SX Model and Year

The Nissan 240SX was available in several different trims and body styles, each with potentially different wheel options. This section breaks down the specific OEM wheel specifications for each model year and trim.

1989-1990 Nissan 240SX (S13)

The first generation of the 240SX, known as the S13, featured several sub-models including the base model, XE, and SE trims. These models were available in both hatchback and coupe body styles.

Bolt Pattern (PCD): 4x114.3mm

Base & XE Models:

  • Diameter: 14 inches
  • Width: 5.5 inches
  • Offset: +40mm (typically)
  • Center Bore: 66.1mm

SE Models:

  • Diameter: 15 inches
  • Width: 6 inches
  • Offset: +40mm (typically)
  • Center Bore: 66.1mm

Note: Some early production models may have slight variations. Always verify with your vehicle's information label or a trusted tire shop.

1991-1994 Nissan 240SX (S13)

The S13 received minor cosmetic updates during this period. Wheel specifications generally remained the same, but there might be slight variations depending on the trim level.

Bolt Pattern (PCD): 4x114.3mm

All Models:

  • Diameter: Typically 15 inches, some base models might have 14 inches.
  • Width: 6 inches
  • Offset: +40mm (typically)
  • Center Bore: 66.1mm

LE (Limited Edition) Models:

The LE models were equipped with similar wheel specifications as the SE models.

  • Diameter: 15 inches
  • Width: 6 inches
  • Offset: +40mm (typically)
  • Center Bore: 66.1mm

1995-1998 Nissan 240SX (S14)

The second generation of the 240SX, known as the S14, featured a more rounded and modern design. A significant change was the introduction of a 5-lug bolt pattern on certain models.

Base Models:

Bolt Pattern (PCD): 4x114.3mm
  • Diameter: 15 inches
  • Width: 6 inches
  • Offset: +40mm (typically)

  • Diameter: 16 inches
  • Width: 6.5 inches
  • Offset: +40mm (typically)
  • Center Bore: 66.1mm

Important Note: The switch to a 5-lug bolt pattern on the SE models in 1997 and 1998 is a key difference. Make sure to verify the bolt pattern of your specific vehicle before purchasing wheels.

Why Choose OEM Wheels?

While aftermarket wheels offer a wide range of styles and sizes, OEM wheels have several advantages:

  • Guaranteed Fitment: OEM wheels are designed specifically for the 240SX, ensuring proper fitment and compatibility with the car's suspension and braking systems.
  • Durability and Reliability: OEM wheels are typically manufactured to high standards, ensuring durability and resistance to damage.
  • Original Aesthetics: If you're restoring your 240SX to its original condition, OEM wheels are the perfect choice to maintain its authentic look.
  • Cost-Effective: Used OEM wheels can often be found at a lower price than new aftermarket wheels.

Where to Find OEM Wheels

Several sources can help you find OEM wheels for your Nissan 240SX:

  • Online Marketplaces: Websites like eBay, Craigslist, and Facebook Marketplace often have listings for used OEM wheels.
  • Junkyards: Local junkyards can be a good source for finding inexpensive OEM wheels, especially for older models.
  • Online Nissan Parts Retailers: Many online retailers specialize in selling genuine Nissan parts, including OEM wheels.
  • Nissan Dealerships: While more expensive, Nissan dealerships can provide new OEM wheels.
  • 240SX Forums and Clubs: Online communities dedicated to the 240SX are great places to find people selling OEM wheels.

When purchasing used OEM wheels, carefully inspect them for any signs of damage, such as bends, cracks, or excessive wear. It's also a good idea to have them balanced before installing them on your vehicle.

Considerations When Choosing Replacement Wheels

While sticking to OEM specifications is generally recommended, there are situations where you might consider using wheels with slightly different specifications. Here are some factors to keep in mind:

  • Tire Size: Changing the wheel diameter or width may require adjusting the tire size to maintain proper rolling diameter and avoid rubbing.
  • Offset: Altering the offset can affect the car's handling and appearance. A lower offset will push the wheels further out, while a higher offset will pull them in. Be careful not to choose an offset that causes the wheels to rub against the fenders or suspension components.
  • Brake Clearance: If you've upgraded your brakes, make sure the wheels have enough clearance to accommodate the larger calipers.
  • Hub Centric Rings: If the center bore of the wheel is larger than the hub diameter of your car, you'll need to use hub centric rings to ensure proper centering and prevent vibrations.

Upgrading to 5-Lug on a 4-Lug 240SX

Many 240SX enthusiasts upgrade their 4-lug S13 to a 5-lug configuration. This often involves swapping the hubs and axles from a 5-lug S14 or using aftermarket conversion kits. This allows for a wider selection of wheel options and improved braking performance. This conversion requires a substantial amount of mechanical skill and resources, consult with a professional before attempting.

Important: Performing a 5-lug swap is a significant modification that may affect your car's handling and safety. Be sure to research the process thoroughly and consult with experienced professionals before undertaking this project.

Always prioritize safety and proper fitment when choosing wheels for your Nissan 240SX. By understanding the OEM specifications and considering the factors outlined in this guide, you can make an informed decision that enhances your car's performance, appearance, and overall driving experience.
