If you’re answering the call of the wild, you’ll need a vehicle capable of traversing rugged terrain. Whether you’re planning a trip into the backcountry or just want to improve your street ride, the right off-road gear is essential.
서울운전연수Rock crawlers, desert pre-runners and trail hounds require vehicles with low-range crawler gearing, high ground clearance and skid plates. These upgrades can make your truck or SUV trail-ready.
What is an Off-Road Vehicle?
The term off-road vehicle applies to four-wheeled motorized vehicles that traverse rugged terrain, primarily away from paved roads. These include All-terrain Vehicles (ATVs), Utility Terrain Vehicles (UTVs, also called side-by-side vehicles) and snowmobiles. OHVs may be powered by gasoline, electric or other means. The traction they provide is essential for negotiating difficult terrain, such as rocky or muddy trails or crossing sandy beaches.
While millions of Americans enjoy the versatility of truck- and SUV-based all-wheel drive vehicles, a small number feel an inexorable pull toward nature and the road less traveled. These intrepid explorers invest time and money in modifying factory trucks and SUVs into off-road warriors capable of chewing up dirt roads, crawling over rocks and climbing near-vertical hills.
Those who aren’t ready to spend big bucks on a full-on 4×4 will find plenty of options at their local automotive parts shop. For example, a few simple accessories can help a 2022 Subaru Forester Wilderness improve approach, departure and ramp breakover angles, while a new set of Yokohama Geolandar all-terrain tires increases ground clearance.
For those who are above a bow-tie badge but still crave a full-size SUV with some serious off-road chops, GMC’s Yukon and Yukon XL offer an off-road trim called AT4. This upgrade includes Bilstein monotube shocks, 33-inch General Grabber tires, a front skid plate and tow hooks, a rear locker and more.
Four-Wheel Drive
Four-wheel drive, which sends power to all four wheels of the vehicle for optimal traction, is often found on larger 서울운전연수 vehicles that are designed with off-road abilities. This type of drive helps these vehicles move over rocky terrain or snowy roads with ease and allows the driver to maintain control over the vehicle in dangerous driving conditions.
Most drivers think of 4WD when they hear the term “four-wheel drive.” This is probably because this system is found primarily in trucks and truck-based SUVs that are designed with off-road capabilities. However, many cars today offer this option as well. This is sometimes called AWD (all-wheel drive) and can be full-time or part-time depending on road conditions.
There are a number of different systems that power all four wheels in a vehicle. Most of these have selectable modes and locking differentials to provide better traction in specific situations. For example, if you are climbing up a steep hill or trying to navigate muddy or snowy roads, it is a good idea to engage the low-range mode of your four-wheel drive vehicle. However, you should be sure to switch back to the normal two-wheel-drive mode as soon as possible to prevent damaging your axles or transfer case.
The first four-wheel drive automobile was created in 1893 by a British engineer named Bramah Joseph Diplock. This early system used two separate engines and gearboxes to power both the front and rear wheels of a vehicle. The system was very heavy, and it took a lot of skill to drive, but it provided enough traction to allow the vehicle to travel over rough terrain.
Tires
A tire is a pneumatically inflated rubber element that transfers power from the car to the road surface, providing grip and absorbing shock. It also protects the rim of the wheel from damage by contact with rough surfaces. A tire can have tread patterns, rubber compounds and other features to improve performance under specific conditions.
For example, a tire designed for off-road use may have a deeper tread pattern to provide traction in dirt, sand and mud. Such tires are usually marked with an “MT” or “mud terrain” designation. Another option is to select snow-rated tires, which have a tread pattern that helps them maintain traction on ice and snow.
Regardless of the specific type, all off-road vehicles should have four-wheel drive and enough ground clearance to allow them to go over rocks, logs, ruts, mud and creeks without sustaining damage. Drivers should also consider using a suspension seat to reduce the amount of force transmitted through the body as the vehicle slams into bumps and craters.
Tires are a major expense, so it’s important to select the right ones for your off-road vehicle. It is also critical to inspect them regularly, since old or worn tires are more prone to deterioration and can cause dangerous driving conditions. Recycled tires are a good option, as they contain steel and other materials that are needed in other industries. Crumb rubber—granulated rubber that can be used for playgrounds, surfacing for athletic tracks, speed bumps and other applications—are another valuable recycling product.
Wheels
A wheel is an essential component of any vehicle, but especially an off-road vehicle. It has to be able to withstand a lot of abuse from rough terrain, and it needs to have a big enough surface area to provide good traction.
There are lots of different types of wheels, and they come in many sizes. Basically, they consist of the spokes (the rods that run from the center disc to the outer edge), the rim, and the hub. Some wheels are made from alloy (a combination of metals), while others are steel.
The spokes are usually made from aluminum, which reduces the weight of the wheel. This helps the vehicle get better fuel economy and reduces strain on bearings and other parts of the wheel assembly. However, some wheels are made from steel, which is stronger and provides a little more load capacity.
Tracks offer a lower ground pressure than wheels, which is helpful in soft surfaces such as mud or snow. However, tracks aren’t the right choice if you need high speed or efficiency.
If you’re serious about off-road driving, you might want to consider equipping your vehicle with a suspension seat. These seats feature a web of webbing under the seat cover that reduces the force of impacts on the driver’s butt and makes it easier to drive over obstacles.
