The 1989 GMC Sierra 1500 I (GMT400) Club Coupe SWB Wideside has a length of 5674 mm (223.3 inches), a width of 1951 mm (76.8 inches), and a height of 1793 mm (70.6 inches). These dimensions make it a sizable pickup truck with a strong road presence, typical of late 1980s full-size trucks designed for durability and utility.
The maximum weight (gross vehicle weight rating or GVWR) of the 1989 GMC Sierra 1500 I (GMT400) Club Coupe SWB Wideside is 2812 kg, which is approximately 6200 lbs. This weight rating reflects the truck's capacity including passengers, cargo, and the vehicle itself. A higher GVWR allows better towing and payload capabilities but requires robust suspension, brakes, and drivetrain components to maintain performance and safety.
The GMC Sierra 1500 I Club Coupe SWB Wideside (1989) typically uses tire sizes 235/75 R15 or 245/75 R16. These tires offer a good balance of ride comfort, load capacity, and off-road capability suitable for a full-size pickup truck, supporting the vehicle's stability and handling under various driving conditions.
The dimensions of the 1989 GMC Sierra 1500 I measuring 5674 mm (223.3 inches) in length, 1951 mm (76.8 inches) in width, and 1793 mm (70.6 inches) in height mean it is quite large compared to typical passenger cars. Standard residential garages usually range from about 5500 mm (18 feet) in length and 2700 mm (9 feet) in width. The truck might fit lengthwise if the garage is on the larger side or if it has a deep garage, but width and height clearance should also be considered. In many cases, parking this truck in a standard single-car garage will be a tight fit or might require a double garage or specialized parking space.
Compared to its predecessor generation (the GMT400 replaced the older GMT400-based 1973-1987 Sierra models), the 1989 GMC Sierra 1500 I showed an evolution in size and design. The GMT400 generation introduced a more aerodynamic and modern styling, while typically maintaining similar or slightly increased overall dimensions. The Sierra 1500 I Club Coupe SWB Wideside at 5674 mm in length and 1951 mm in width offered a more refined design with better dimensions suited for both work and daily driving. The new generation also brought improvements in chassis rigidity and interior comfort over earlier models.
With an overall width of 1951 mm (76.8 inches) without mirrors, the 1989 GMC Sierra 1500 I is relatively wide for its time, providing a spacious cabin and wider cargo bed but potentially challenging tighter urban maneuvers. While this width helps stability and interior shoulder room, drivers should be cautious in narrow streets or parking lots. This width is typical of full-size trucks and reflects a balance between usability and comfort.
The vehicle height of 1793 mm (70.6 inches) places the 1989 GMC Sierra 1500 I in the range of medium-to-tall full-size pickups. This height contributes to a commanding road presence, better visibility for the driver, and the ability to overcome rough terrain and obstacles. Additionally, it may affect garage clearance and accessibility for some users, but it remains a typical height for trucks designed with both on-road and off-road versatility.
In comparison to other full-size pickups from the late 1980s, such as the Ford F-150 and Dodge Ram trucks, the GMC Sierra 1500 I stands competitive in dimensions, with its length of roughly 5674 mm (223.3 inches) and width near 1951 mm (76.8 inches). These measurements place it on par with typical American full-size pickups of that era, combining a robust frame with practical size for work and personal use. The Sierra's size balances cargo capacity without being overly cumbersome in urban settings compared to some heavier-duty models.
The 1989 GMC Sierra 1500 I Club Coupe SWB Wideside is designed primarily as a versatile pickup truck suitable for both daily transportation and work-related functions. Its shorter wheelbase (SWB) and Wideside bed offer easier maneuverability and increased cargo width for hauling medium-sized loads. It’s ideal for users needing a truck that can handle towing, transport of tools and materials, or recreational activities requiring storage space, while still providing cabin comfort for passengers.
The Wideside bed on the GMC Sierra 1500 I (1989) was designed to maximize cargo volume without significantly increasing the truck's footprint or height. This design uses flat, wide bed sides rather than the traditional stepside with pronounced fenders, allowing wider cargo loads and easier loading/unloading on the sides. This configuration made the Sierra more versatile for carrying bulky or wide items, which appealed to commercial users and consumers needing practicality combined with a sleek exterior design.
