Trucks will tend to slide sideways before rolling over — the tyres will slip sideways a little. Stop if the slide puts you off the edge of the track. If it is clear downhill and a rollover is imminent, immediately turn the vehicle into the slide and drive it down.

If that is not an option, and you are going over, turn the vehicle off and hold on to your seat-bottom while hoping that the seat belt works properly. Reducing tire pressure will increase traction on gravel and sand. For most 4-wheeling purposes, a tire pressure of 18 to 20psi will be adequate. Highway pressure is another consideration altogether.

The tyre is marked on the side, i. In essence, that one tyre could hold my Defender up. Depending on the weight of the loaded vehicle and the size of tyre, a tyre pressure of between 28 and 35psi works in most on-highway applications. Cross ditches or logs at an angle so that one wheel at a time goes over the obstacle; the other three help the one wheel to climb over. Dropping the tyre into a ditch or crack in a rock can put you and your truck in a vulnerable position.

Sometimes the vehicle pitches and one or more tyres will catch air. Be very deliberate and careful when approaching this challenging section of any trail. Logs can bounce up and catch the undercarriage, so come off these obstacles slowly and carefully.

Turn the vehicle at an angle to facilitate the one tyre at a time approach. Be careful not to allow one of the front tyres and one of the rear tyres to get in the ditch at the same time.

One of the most crucial aspects to off-roading is understanding the absolute importance of tyre pressure. Among the most pertinent tyre pressure considerations in regards to summer, off-roading is utilizing optimum sand tyre pressure.

Optimum sand tyre pressure is a combination of many things, of which truck-owners myths are least productive. However, your tyres, their construction methods and materials, what your car weighs, how it is loaded, and wheel width, all play into the sand-pressure tyre formula with predictable results. Why low pressure works, and how to determine your best sand pressure, follows: Sand rail people and mud boggers know big feet work better as well.

Tread pattern should be chosen based on the intended use of your truck. The most popular tread pattern for all-around off-road use is a mud terrain pattern. The mud terrain or mud tyre pattern is characterized by large lugs on the tyre with big voids between these lugs.

The large lugs provide plenty of bite in low traction conditions while the big voids allow the tyre to clean itself by throwing off mud or other material when spinning, thus providing a good bite on every rotation of the tyre. These tyres are also very popular for rock crawling as the large lugs can provide a way of gripping and pulling the tyres up and over irregular rocky edges where a smoother pattern would just spin.

The biggest disadvantage of these patterns is that they run rough and loud on the highway. To reduce this problem; choose a tyre with irregular or asymmetric spacing of the lugs and voids to reduce harmonic vibration at highway speeds. There are also situations such as light powdery snow or sand where an all-terrain pattern would be better. The general purpose all terrain tyre generally has an interlocked tread pattern with siping small cuts on the tread blocks.

The voids in these tyres are usually much smaller than those on tyres designed for use in the mud. The more dense pattern of blocks and smaller voids make these tyres quieter on the street. It also increases the surface area of the tread which gives the tyre improved flotation on surfaces such as light powdery snow or sand. The increased siping can be important in the snow where it is the number of edges, even quite small edges, biting into the snow that provides the traction.

The downside is that the smaller voids cannot clean themselves as easily of packed mud or slush. There are equal proportions of right-clawed and left-clawed males: Another type of asymmetry is directional, that is, the left and right sides differ, but always in the same direction.

The bulk of the heart, for instances is on the left side of the body, which is why you feel your heartbeat on that side. Quirks of Human Anatomy gives more examples: Our right lung has three lobes but our left lung only two. Our heart is shifted to left, our spleen is located on the left, and our stomach bulges to the left, whereas our liver is shifted to the right. Our colon curls into a question mark, although its exact path can vary from person to person.

These kinds of directional asymmetries are not infrequent. Another example of directionality are some nocturnal owls in which the ear openings are asymmetrical ; this helps them localize prey. In the barn owl, the left ear opening is higher than the right.

These species are directionally asymmetrical, but in opposite ways. Here, however, we face a genetic problem:
