What Are OBS Wheels?

OBS Wheels, short for "Old Body Style" wheels, refer to wheel designs that were popular on trucks and SUVs from the late 1980s to the late 1990s. This term is particularly associated with Chevrolet and GMC vehicles, specifically the 1988-1998 models, however, also includes OBS Fords as well.

How Much Do OBS Wheels Cost?

The cost of OBS (Old Body Style) wheels varies widely based on factors like brand, material, size, design, and whether they're new or used. Aftermarket OBS wheels, which are newly manufactured to fit OBS vehicles, typically range from around $100 to $300 or more per wheel. Prices vary depending on brand quality, material (such as steel or alloy), and design intricacy.

For those seeking originality, OEM (Original Equipment Manufacturer) wheels from the OBS era, especially in good or refurbished condition, can command higher prices. These genuine vintage wheels often cost between $150 and $500 per wheel, sometimes even more, depending on their rarity and condition.

Custom-designed or limited edition wheels for OBS trucks are at the higher end of the price spectrum, potentially exceeding $500 per wheel. These cater to enthusiasts looking for unique or specialized designs.

In contrast, used OBS wheels present a more affordable option, with prices heavily dependent on condition and source. These can range from as low as $50 to several hundred dollars per wheel.

When considering a purchase, it's crucial to factor in additional expenses like tires, installation, and accessories like lug nuts or hub-centric rings. Prices can also fluctuate based on location and seller, so it's wise to compare options across different retailers.

Who Makes OBS Wheels?

OBS (Old Body Style) wheels, popular for Chevrolet and GMC trucks from the late 1980s to the late 1990s, are produced by a mix of original equipment and aftermarket manufacturers. For those seeking authentic OBS wheels, General Motors, the parent company of Chevrolet and GMC, is the original equipment manufacturer. These OEM wheels are particularly valued for restoration projects or preserving the vehicles' originality.

In the aftermarket sector, numerous companies produce wheels compatible with OBS vehicles. Well-known in the aftermarket wheel industry, brands like American Racing, Pro Comp, and Mickey Thompson offer a wide range of styles, sizes, and materials, allowing for extensive customization options for OBS trucks.

Additionally, some specialized wheel shops provide custom-made wheels tailored to fit OBS vehicles. These shops can create unique wheels based on specific customer requests, offering personalized designs, sizes, and finishes.

For those interested in vintage and classic styles, certain companies focus on producing or refurbishing wheels specifically for classic and vintage vehicles, including OBS trucks. These specialists often aim to reproduce the aesthetic of original wheels while sometimes incorporating modern materials and manufacturing techniques.

Furthermore, a variety of online retailers and auto parts stores offer a selection of wheels suitable for OBS trucks, sourced from different manufacturers. This wide availability of options from both OEM and aftermarket sources allows owners of these classic trucks to either maintain their original look or opt for a more customized appearance.

OBS Wheel Fitment Considerations 

When it comes to fitting wheels on Old Body Style (OBS) trucks, typically Chevrolet and GMC models from the late 1980s to the late 1990s, several important considerations come into play. The bolt pattern is crucial, with most OBS trucks featuring a 5x5 inch (5x127mm) pattern. Ensuring the new wheels match this pattern is essential for a proper fit.

The size of the wheel, including both diameter and width, significantly impacts the vehicle's look and performance. Commonly, OBS trucks can accommodate wheels from 15 to 18 inches in diameter. The choice of width affects the truck's stance; wider wheels may provide an aggressive look but must be carefully chosen to avoid rubbing against the fenders.

Offset and backspacing are key in determining how the wheels align with the fender and suspension components. Proper offset ensures adequate clearance from suspension parts and the wheel well, preventing any issues with rubbing. Similarly, the hub bore of the wheel needs to align with the vehicle's hub. If the wheel’s hub bore is larger, hub-centric rings might be necessary to ensure correct centering.

Tire selection is also vital. The tires must be compatible with the wheel's dimensions and fit comfortably within the wheel well, allowing for full motion without any rubbing. This aspect is particularly important for trucks, which might be used for heavier loads or towing.

Additionally, the load rating of the wheels should not be overlooked. As OBS trucks are often used for hauling, it's important to choose wheels that can handle the vehicle's weight and towing demands.

Lastly, aesthetic preferences such as design, color, and finish are subjective but important. They contribute to the overall appearance and individuality of the vehicle. Given these various factors, it's highly recommended to consult with a wheel and tire professional to ensure that the chosen wheels are not only visually appealing but also safe and suitable for the vehicle's specific requirements.

Common OBS Wheel Bolt Patterns

Old Body Style (OBS) Chevrolet and GMC trucks, which were produced from 1988 to 1998, have distinct wheel bolt patterns that vary based on the truck series. These patterns are a key aspect of the truck's design, influencing the type of wheels that can be fitted.

For the half-ton trucks, which fall under the 1500 series, the typical bolt pattern is a 5-lug design. This pattern generally measures 5x5 inches, also known as 5x127mm. It's a common setup for vehicles in this category, providing a balance between strength and compatibility with various wheel designs.

Moving to the three-quarter-ton (2500 series) and one-ton (3500 series) trucks, the bolt patterns become larger to accommodate the increased load-bearing requirements. The 2500 series usually features a 6-lug pattern, with dimensions of 6x5.5 inches or 6x139.7mm. In contrast, the 3500 series, designed for the heaviest loads, typically comes with an 8-lug pattern. This larger pattern measures 8x6.5 inches or 8x165.1mm. These variations are crucial for truck enthusiasts and professionals to consider when customizing or repairing their vehicles.

OBS Wheel Hub Bores

For Old Body Style (OBS) trucks, which include Chevrolet, GMC, and Ford models produced mainly from 1988 to 1998, the hub bore size is an important consideration for wheel compatibility. The hub bore, also known as the center bore, is the central hole in a wheel that aligns it properly with the vehicle's hub.

In the case of Chevrolet and GMC OBS trucks, a common hub bore size is about 78.1mm. This size is standard for many models from these manufacturers during the OBS era.

Ford OBS trucks, on the other hand, tend to have different hub bore sizes. For instance, Ford F-150 trucks from this period often have a hub bore size around 87.1mm. 

It’s essential to note that these sizes can vary based on specific models and configurations. When selecting aftermarket wheels, it’s crucial to ensure that the hub bore size of the wheels is either the same as or larger than the vehicle's hub size. Wheels with a larger hub bore can be adapted with hub-centric rings, but wheels with a smaller hub bore than the vehicle's hub will not fit. Always verify the exact hub bore size for your specific truck model before making a purchase.

OBS Wheel Aftermarket Vs OEM Options

When considering wheel options for Old Body Style (OBS) trucks, which include Chevrolet, GMC, and Ford models from the 1988 to 1998 era, the choices broadly fall into two categories: OEM (Original Equipment Manufacturer) wheels and aftermarket wheels. Each type offers different benefits and characteristics.

OEM wheels are designed specifically for a particular model, ensuring a perfect fit in terms of bolt patterns, hub bore, and offset. This design guarantees compatibility with the vehicle's suspension and braking systems, offering a balanced and original look. These wheels are made to meet the manufacturer's standards for performance and durability, making them a reliable and long-lasting choice.

Aftermarket wheels, on the other hand, offer a wide range of styles, sizes, and finishes, allowing for greater customization of the vehicle. They can alter the look and feel of the truck, potentially improving performance and handling depending on the choice of size and weight. However, it's important to carefully select aftermarket wheels to ensure they are compatible with the vehicle's specifications, as improper fitment can lead to issues with handling, tire wear, and even safety.

In summary, while OEM wheels provide assured compatibility and quality, aftermarket options open up possibilities for customization and performance enhancements. Truck owners should consider their priorities, whether it's maintaining the original look and feel of the truck or personalising it to their taste and needs.

Popular OBS Wheel Brands 

There are a variety of popular OBS wheel brands, however, let’s go through some of the most popular and notable.

How to Choose the right OBS Wheels

Choosing the right wheels for an Old Body Style (OBS) truck, like those from Chevrolet, GMC, and Ford produced between 1988 and 1998, involves considering several factors to ensure compatibility and performance.

Firstly, wheel size is paramount. Larger wheels may offer a more aggressive look and can improve handling, but they can also affect ride quality and may require modifications to the truck. Conversely, smaller wheels might provide better ride comfort and fit more easily without modifications. It's crucial to balance aesthetics with functionality.

Secondly, consider the wheel's bolt pattern. OBS trucks have specific bolt patterns, typically 5, 6, or 8-lug configurations depending on the model and series of the truck. Ensuring that the new wheels match the truck’s bolt pattern is essential for proper fitment.

The third aspect to consider is the offset and backspacing of the wheel. These measurements determine how the wheels sit in relation to the body of the truck. Incorrect offset or backspacing can lead to issues like tire rubbing against the body or suspension components. It's important to choose a wheel offset that aligns well with your truck's specifications.

Material and build quality are also key. Alloy wheels are popular for their balance of strength and light weight, which can improve handling and fuel efficiency. However, for heavy-duty or off-road use, stronger materials like steel might be preferable. Consider your truck’s usage to select the appropriate wheel material.

Lastly, aesthetics play a significant role. Wheels significantly impact the overall look of the truck. Choose a style that complements your truck's design and your personal taste. Whether you prefer a classic, rugged, or modern look, there's a wide range of designs available in the market to suit various preferences.

By carefully considering these factors, you can choose the right wheels for your OBS truck that blend style, functionality, and performance.
