All Terrain Tires For Trucks, First Drive: 2019 GMC Sierra AT4-The Otay Mountain Truck Trail is fun and picturesque, but not particularly difficult.In reality, you should qualify it. From a psychological point of view it is very difficult. As the wrapper around the mountain, the road covered by the ground is generally wide enough to adjust the bands to the velvet channels and to mark the water. At the edge of the hill slopes directly and there is no fence. Turn the right rear wheel too fast into the hole and you can land on the left rear wheel, which approaches the rim.
However, it is true that no one with an outside experience or a minimum of self-sufficiency will not do this. At a reasonable pace, the Sierra AT4 GMC 2019 drove the road so easily that we did not even bother to skip the bass transfer. A panoramic view of San Diego and the border with northern Mexico, across the border, had more offers than the truck’s performance.
The Sierra AT4 is able to do this, and Southern California is full of fantastic all-terrain trails. Why do you choose this? It does not matter: the trip was fun, and we ended up short and off-road trails that could show AT4: the large amounts of dirt play and climb up the slope. Rock 21 degrees, a corner controlled by an integrated inclinometer.

But it is terrible, is not it?
Not really. The problem is that snowmobiles are often full of turns and noise and are rare every day, but the Sierra AT4 does not look that way. On the roads and byways around San Diego the tires bring some noise, but the cab is usually quiet and the suspension is stable and smooth. The gearbox had one or two unexpected speed changes, but this is achieved with many automatic gearboxes with 10 speeds. Because it is fun, this truck is a good deal.
Of course this is not the Ford F-150 Raptor, but it is also cheaper. Ram Rebel is closer to comparison and more power available in Sierra AT4 at a slightly higher price can be a solution ……….
