Tires for rock, caliche and clay
New Mexico’s unpaved surfaces are volcanic rock, caliche and badland clay rather than soft sand. The BLM describes the Quebradas and Chain of Craters byways as rugged in several areas, with blind curves and hills, and the Park Service calls the last 4.5 miles into Chaco very rough. Buy a tire with a carcass that will take sharp rock, and carry a full-size spare, a plug kit and a compressor.
Wet clay is the other half of the problem. The BLM says the Chain of Craters road is difficult to navigate when wet and the roads into Bisti/De-Na-Zin can turn slippery or impassable after rain or snow.
Tires are the only part of the vehicle that touches the ground, and on a loaded rig they work close to their limits. A good tire shop starts with load rating and size, then tread. It will also tell you when the tire you want will rub, need different wheels or throw off your gearing.

How to choose tires for overland travel
Tread pattern is the last decision, not the first.
01Match the load rating to your real axle weights, not to the badge on the fender.
02All-terrain tires suit most overland travel. Mud-terrains are louder, heavier and wear faster, and earn it only in real mud and rock.
03Buy five. A matching full-size spare that you rotate in is worth the money when the nearest tire shop is a day away.
04Check the wheels too. Wheels have load ratings, and the wrong offset stresses bearings and rubs.
05Ask whether the shop can move or reprogram your tire pressure sensors.
What to have ready before you ask for a quote
A tire quote is quick when the shop knows what the tire has to carry.
01Vehicle, current tire size and wheel size
02Lift height, if any
03Loaded weight, or a list of what is on the vehicle
04Where you drive most: pavement, gravel, rock, sand, snow
05A budget range for five tires
Questions people ask
What does load range mean?
It describes how much weight a tire can carry at a given pressure. Heavier builds, vans and truck campers usually need a higher load range than the vehicle came with. The tire's sidewall and the placard in the door jamb are the places to start, and a tire shop can work through the numbers with you.
How big can I go?
Every platform has a size that fits at stock height, a size that fits with a modest lift, and a size that needs trimming and gears. Tell the shop your lift and wheels and ask what fits without rubbing at full steering lock and full compression.
Should I air down?
On washboard, sand and rock, lower pressure gives a better ride and more traction and is easier on the vehicle. It also means you need a way to air back up before pavement. How low depends on your tire, your weight and your speed, so ask your tire shop and start conservatively.
How high is New Mexico?
From Carlsbad at 3,108 feet to Wheeler Peak at 13,161.
Altitude decides what your engine, your brakes and your lungs have to work with, and how late in the year the passes open.
