Overlanding 101
A beginner-friendly guide to exploring Colorado’s mountains, trails, and campsites safely and confidently.
Whether you’re new to overlanding or simply visiting Colorado for the first time, this guide covers some of the most important things to understand before heading into the backcountry. Colorado offers extraordinary opportunities for vehicle-based exploration, but changing weather, high elevation, rugged roads, remote locations, and sharp terrain require preparation and good judgment.
Please take a few minutes to read this guide before your trip. Understanding your vehicle, tire pressures, trail conditions, navigation, and basic backcountry practices can make the difference between a great adventure and an avoidable problem.
What Is Overlanding?
Overlanding is self-reliant vehicle travel into remote places where the journey is often as memorable as the destination.
Unlike an off-road park or recreational rock crawling, overlanding generally emphasizes:
- Scenic and rugged backcountry routes
- Dispersed camping
- Self-sufficiency
- Exploration and adventure
- Responsible outdoor ethics
Colorado is particularly well suited to overlanding because many of its historic mining roads, Forest Service roads, and mountain passes provide access to spectacular areas that would otherwise be difficult to reach.
Why Colorado Is Perfect for Overlanding
Colorado offers an incredible mix of:
- High alpine passes reaching 10,000–13,000 feet
- Historic mining roads and ghost towns
- Wildflower basins and alpine lakes
- Remote backcountry campsites
- Easy scenic roads and challenging technical trails
From Denver’s Front Range to the San Juan Mountains surrounding Ouray, Silverton, Telluride, and Lake City, every region offers something different.
That variety also means conditions can change dramatically from one road to another. A route that begins as a smooth dirt road can become rocky, narrow, steep, or exposed several miles later.
What You Need to Know Before Your Trip
1. Trail Difficulty Basics
Colorado trails generally fall into three broad categories:
Easy / Beginner
Mostly gravel or maintained forest roads with mild grades and few significant obstacles.
Examples: Boreas Pass, Switzerland Trail.
Moderate
May include rocks, ruts, water crossings, narrow sections, shelf roads, and moderately technical terrain.
Examples: Yankee Boy Basin, Owl Creek Pass.
Advanced / High Alpine
May include steep climbs and descents, large rocks, significant exposure, narrow shelf roads, tight switchbacks, and obstacles requiring careful wheel placement.
Examples: Black Bear Pass, Poughkeepsie Gulch.
Never assume that having a capable four-wheel-drive vehicle automatically makes a trail appropriate for your experience level. Driver judgment is just as important as vehicle capability.
If you’re uncertain about a route, ask us. We’re happy to help you choose trails appropriate for your experience and comfort level.
2. Tires, Tire Pressure & Airing Down
Tires are one of the most important pieces of equipment on an overland vehicle. Proper tire pressure improves traction, ride quality, vehicle control, and tire durability — and can substantially reduce the chance of tire damage on rocky trails.
Door-Jamb Pressure vs. Our Actual Tire Pressure
The tire-pressure label inside the driver’s door reflects the vehicle manufacturer’s specified cold pressure for the vehicle’s original tire and load configuration.
Peak Overland vehicles may be equipped with larger, higher-capacity all-terrain tires that differ substantially from the original factory tires. Simply inflating an oversized tire to a number on the original door placard does not necessarily produce the ideal contact patch or ride characteristics for the vehicle’s current tire setup.
We evaluate tire pressure using methods including the chalk test, which helps determine how evenly the tire’s tread contacts the road. As a result, the pressures we use with our oversized all-terrain tires may be lower than the original door-jamb recommendation.
Excessive pressure for the actual tire, vehicle weight, and conditions can produce a harsher ride, reduce the tire’s ability to conform to uneven terrain, contribute to uneven tread wear, transmit more impact into the vehicle and suspension, and make the tire more vulnerable to certain types of trail damage.
Why We Air Down Off Road
“Airing down” means intentionally reducing tire pressure before traveling on rough terrain.
Depending on the vehicle, tire, load, and terrain, trail pressures may commonly be in the 15–20 psi range. If you are unsure what pressure is appropriate for your specific Peak Overland vehicle, contact us before airing down.
Lowering tire pressure off road provides several important benefits:
- Better traction: The tire develops a larger, more compliant contact patch on rock, dirt, sand, mud, and other loose surfaces.
- Improved ride quality: The tire absorbs considerably more of the small rocks, washboard, and irregular terrain before those impacts reach the suspension and occupants.
- Reduced risk of some tire damage: A properly aired-down tire can flex and conform around rocks and sharp edges instead of striking them as rigidly as a highly inflated tire.
- Better vehicle control: Increased tire compliance and traction can improve stability and control on uneven terrain.
- Reduced stress on the vehicle: Allowing the tires to absorb smaller impacts reduces the shock transmitted through wheels, suspension components, and the rest of the vehicle.
- Reduced trail impact: A larger tire footprint can reduce concentrated ground pressure on soft terrain.
Important: Lower pressure also requires slower speeds and careful driving. Extremely low pressure, excessive speed, or aggressive cornering can cause a tire to lose its bead or suffer other damage.
Reinflate Before Highway Driving
Trail pressures are not appropriate for sustained highway speeds. Always reinflate the tires after leaving the trail and before extended highway driving.
For our current vehicle and tire configurations, 30 psi or greater is generally acceptable for normal highway travel. The exact pressure may vary with the vehicle, tire temperature, load, and conditions.
If you have questions about the appropriate pressure for your vehicle, contact Peak Overland.
Understanding TPMS Warnings
Every vehicle is equipped with a Tire Pressure Monitoring System (TPMS). It is important to understand that a low-pressure warning does not automatically mean you have a puncture or damaged tire.
Our larger all-terrain tires may operate at pressures closer to the vehicle’s preset TPMS warning threshold than the original factory tire configuration. This means a relatively small pressure change can sometimes trigger a warning.
Temperature also has a significant effect on tire pressure. A vehicle may leave Denver during hot summer weather and then spend the night thousands of feet higher in the mountains where temperatures are dramatically colder. As the tire and outside temperature decrease, tire pressure naturally decreases as well.
For example, a tire set in the mid-30 psi range in warm Denver conditions may read several PSI lower on a cold mountain morning without having any leak at all.
If a TPMS warning appears:
- Check the actual pressure of all four tires.
- Compare the suspect tire with the other tires.
- If necessary, add air and note the pressure.
- Check the tire again later to determine whether pressure is continuing to fall.
- Look for nails, screws, cuts, sidewall damage, or other obvious problems.
A tire that is at 31–33 psi and remains at approximately that pressure is very different from a tire that is inflated to 35 psi and repeatedly falls to 25 psi. Continuing pressure loss is what indicates that a leak or other problem needs to be investigated.
Our Tire Deflator / Inflator Kit
If you plan to drive off pavement, we strongly recommend adding our optional tire deflator/inflator kit to your reservation.
The kit makes it easy to reduce pressure appropriately before entering rough terrain, monitor tire pressure accurately, and reinflate the tires before returning to highway speeds.
If you plan significant off-road travel, ask us about the appropriate trail pressure for your particular vehicle before your trip.
Punctures, Road Hazards & Tire Damage
Even properly inflated premium all-terrain tires can be damaged. Colorado’s backcountry contains sharp rocks, broken branches, nails, screws, wire, and other debris. Historic mining areas and ghost towns can contain metal debris that has been on the ground for decades.
Tire damage can also occur on ordinary paved roads. A nail or screw picked up on the highway is a road hazard — not a vehicle maintenance failure.
Guests are responsible for tire damage occurring during the rental as a result of road hazards or vehicle use, including punctures, cuts, sidewall damage, bead damage, and damage caused by rocks, nails, screws, metal debris, or other trail and roadway hazards.
If a damaged tire can be safely repaired, the cost of that repair is the guest’s responsibility. If the tire cannot be safely repaired and replacement is required, the cost of the replacement tire may be deducted from the guest’s security deposit in accordance with the rental agreement.
If you experience a tire problem during your trip, contact Peak Overland before authorizing the purchase of a replacement tire whenever circumstances safely allow. We can help determine whether the tire needs immediate replacement, whether the full-size spare should be installed, or whether the vehicle can safely return to an appropriate tire shop.
Do not continue driving on a tire that is rapidly losing pressure, visibly damaged, or unable to maintain a safe pressure.
3. Altitude, Weather & Seasonal Closures
Colorado’s high elevation creates unique conditions:
- Snow can linger into June or July on alpine passes
- Afternoon thunderstorms can form rapidly during summer
- Temperatures may swing 30–40°F or more in a single day
- Conditions can change dramatically with elevation
- Trails may temporarily close after major storms or damage
- Weather can be completely different between nearby towns and mountain passes
Many high alpine passes do not open until mid-June or early July, depending on winter snowpack and spring conditions. Some may close again temporarily or permanently after early-season snowfall.
Always check current weather and trail conditions before committing to a high-elevation route.
4. Navigation Tools
Cellular navigation cannot be relied upon in much of Colorado’s backcountry. Download maps before leaving cellular coverage.
Useful navigation resources include:
- OnX Offroad – user-friendly offline trail maps
- Gaia GPS – detailed topographic mapping
- USFS MVUM maps – official Motor Vehicle Use Maps showing legal motorized routes
Do not rely exclusively on crowdsourced trail ratings. Conditions can change substantially because of erosion, storms, snow, rockfall, or trail maintenance.
5. Communication & Backcountry Safety
Cell service disappears quickly in Colorado’s mountains. In many areas you may be dozens of miles from reliable cellular coverage.
We strongly recommend:
- A Garmin inReach, satellite-capable phone, or similar satellite communication device
- Offline maps downloaded in advance
- Sharing your planned route and expected return time with someone
- Carrying adequate food, water, clothing, and medication for unexpected delays
- Checking weather and trail conditions before entering remote areas
Remember that roadside assistance may be difficult or impossible to provide on unmaintained off-road trails. Even when assistance is available, response times in remote areas can be substantial.
6. Drive for the Terrain
Four-wheel drive increases capability, but it does not eliminate the consequences of poor judgment.
When traveling off pavement:
- Slow down before rough sections rather than braking hard after hitting them.
- Avoid striking rocks, potholes, and ledges at speed.
- Use careful wheel placement instead of relying solely on ground clearance.
- Do not drive faster simply because the suspension makes the road feel comfortable.
- Use an appropriate 4WD mode before you need it.
- Never continue onto terrain you are uncomfortable driving simply because another vehicle made it through.
These vehicles are extremely capable, but capability should provide a margin of safety — not an excuse to take unnecessary risks.

Respect the Vehicle, the Trail & the Backcountry
A successful overland trip isn’t about seeing how much abuse a vehicle can take. The best drivers use the vehicle’s capability to travel smoothly, deliberately, and responsibly.
Slow down, choose your lines carefully, manage your tire pressure appropriately, respect closures and private property, pack out what you bring in, and leave Colorado’s backcountry in better condition than you found it.
If something doesn’t look right with the vehicle during your trip, contact us. A quick conversation can often distinguish a normal condition — such as temperature-related tire-pressure changes — from something that actually requires attention.
