The GMC Sierra showing it's towing and trailering capacity.



With every season comes a list of new demands that rely on the precision engineering of your GMC – many of which hinge on trailering capability. Like a full-body workout, trailering utilizes every muscle in your GMC. So, it’s critical to make sure every system is performing exactly the way it should.


The best place to start is a trip to the Professional Grade service experts at your GMC dealer. They can perform a Multi-Point Vehicle Inspection that covers some of your vehicle’s vital systems. They’ll examine everything from air conditioning, tires, and wipers to your engine, transmission, exhaust, and more.


One area of focus for a vehicle that tows often will be the braking system. When you have hundreds or even thousands of pounds of trailer weight behind your vehicle, the laws of inertia make stopping much more strenuous on your brakes. Features like the Integrated Trailer Brake Controller, which allow the trailer’s brakes to work in coordination with the vehicle’s brakes, help to maximize stopping power. It’s also vital to have high-quality brake components professionally installed and regularly inspected. The Professional Grade experts trust ACDelco and Genuine GM Parts to get the job done right.


Another key contributor to trailering capability is your tire tread wear and load-carrying capacity. The danger involved in trailering, or even just driving, on tires with significant tread wear is obvious. But what is considered acceptable tread depth may not be so obvious. Be sure to consult a MPVI, who will check all tires for wear and damage.


Load-carrying capacity is a measurement of a tire’s internal air volume. Factors such as how fast you’ll be trailering and how much weight you’ll be pulling both affect the temperature of the air in your tire, and in turn affect its tire pressure and load rating. The Professional Grade experts can match your GMC with precisely the right tire style, with exactly the right load rating for the type of trailering you’ll be doing this season.


After all these measures, your GMC can be in prime trailering condition. However, without a proper hitch that has been professionally installed, smooth sailing is not guaranteed. The technicians at your GMC dealer will help you understand the difference among a weight-carrying hitch, weight-distributing hitch, and a gooseneck hitch – and which one you’ll need for your purposes. It’s also a good idea to have them install it so that the turns, hills, and stops you trailer through can be met with confidence.


No matter the season, the Professional Grade service experts stand ready to help your GMC pull its weight – and then some. Make an appointment at your GMC dealer today.
