2015 Chevrolet Suburban (GMTK2YC/G) Dimensions, Size & Specs

The curb weight of the 2015 Chevrolet Suburban ranges between 2569 kg and 2850 kg (5,662 to 6,283 lbs), depending on the trim and equipment levels. Its maximum gross vehicle weight is between 3311 kg and 3402 kg (7,300 to 7,500 lbs). This indicates the total allowed weight of the vehicle including passengers, cargo, and fuel. Given the heavy curb weight typical of full-size SUVs, it is built with robust suspension and frame to handle substantial loads safely.

The 2015 Chevrolet Suburban offers 1113 liters (39.3 cubic feet) of cargo space behind the rear seats, which is already quite generous for a full-size SUV. When the rear seats are folded down, the cargo capacity expands drastically to 3429 liters (121 cubic feet). This flexible cargo space is one of the Suburban’s key selling points, allowing it to carry large loads, whether for family trips or commercial use.

The 2015 Chevrolet Suburban has a ground clearance of 201 mm (7.9 inches). This ride height is typical for a large SUV and allows the vehicle to clear most obstacles encountered during light off-road driving. It enhances the SUV's ability to handle uneven terrain, shallow water crossings, and rough roads comfortably, while still providing a stable on-road driving experience.

Fitting the 2015 Chevrolet Suburban into a standard residential garage can be challenging due to its size. With a length of 5699 mm (224.3 inches) and a width of 2044 mm (80.5 inches), it requires a larger-than-average garage space. Most standard single-car garages are around 6 meters (20 feet) deep and 3 meters (10 feet) wide, so while it might fit snugly lengthwise, clearance for opening doors and maneuvering could be limited. Homeowners should check their garage dimensions carefully or consider a larger or double garage for comfortable accommodation.

At 2044 mm (80.5 inches) wide, the 2015 Chevrolet Suburban is competitive in width compared to other full-size SUVs like the Ford Expedition and GMC Yukon XL. For example, the Ford Expedition from the same era is approximately 2029 mm (79.8 inches) wide, and the GMC Yukon XL is quite similar in width to the Suburban. This makes the Suburban comfortably spacious, offering wide cabin dimensions that contribute to passenger comfort and cargo capacity without being excessively wide for road use.

Compared to its predecessor (the 11th generation), the 2015 Chevrolet Suburban (GMTK2YC/G) saw modest increases in overall size. The length reached 5699 mm (224.3 inches), which is slightly longer, allowing for better interior volume. Width at 2044 mm (80.5 inches) and height at 1889 mm (74.4 inches) also were adjusted slightly to enhance stability and interior space. This generation introduced improvements in aerodynamics and modernized styling while maintaining or improving cargo capacity and passenger room, representing a natural evolution with incremental growth rather than a dramatic size change.

The 2015 Chevrolet Suburban came with various rim sizes including 18-inch (8.5J x 18), 20-inch (9.0J x 20), 22-inch (9.5J x 22 and 22) wheels. Corresponding tire sizes were 265/65 R18, 275/55 R20, and 285/45 R22. Larger rims and wider tires tend to offer improved road grip and handling characteristics, particularly on paved roads, while smaller wheels with higher profile tires absorb bumps better, contributing to improved ride comfort. Thus, rim and tire choice allows owners to balance comfort and sportier driving preferences.

The 2015 Chevrolet Suburban is renowned for its spacious interior, making it highly practical for families and large groups. It offers seating for up to nine passengers with three rows of seats, plus generous headroom and legroom across all rows. The ample cargo space behind the third row (1113 liters/39.3 cubic feet) can carry luggage or groceries comfortably, and folding down rear seats expands cargo capacity dramatically to 3429 liters (121 cubic feet). These attributes make it ideal for long trips, school runs, and transporting sports equipment or gear.

The 2015 Chevrolet Suburban stands out among full-size SUVs for its combination of size, interior volume, and towing capacity. While similar vehicles like the Ford Expedition and GMC Yukon XL closely match the Suburban's length (around 5.7 meters) and width (approx. 2 meters), the Suburban often offers a slight edge in cargo space and maximum payload. Its ground clearance of 201 mm (7.9 inches) and heavy-duty platform support robust towing and hauling. Additionally, the Suburban's luggage space of up to 3429 liters (121 cubic feet) with folded seats is among the best in its segment, offering versatility for both family and commercial uses.
