Choosing Tires for Trucks That Run Highway and Field Roads

Dual-duty vehicles take heat on the highway and cuts on caliche. What to prioritise when one tire has to do both jobs.

A great many trucks on the South Plains split their week between highway miles and caliche. That combination asks for opposite things from a tire, and choosing well is mostly about deciding which compromise you can live with.

What each environment wants

Highway wants a tire that runs cool at sustained speed, wears evenly, is quiet, and rolls efficiently. That points toward a highway or all-season construction with a closed tread pattern.

Caliche and field roads want cut resistance — a stronger sidewall and a more open tread that clears rather than packs. That points toward an all-terrain.

The honest trade-off

• All-terrains run hotter at sustained highway speed because of the more open tread and heavier construction. That matters in a West Texas July.
• They wear faster on pavement and they are noisier.
• They resist cuts substantially better, which on lease and county roads is the failure mode that actually retires tires here.
• Highway tires are cheaper to run until the day one gets cut, at which point the saving evaporates.

Load range matters more than most people think

Load range (C, D, E and so on) describes the tire's construction and its load capacity at a given pressure. A higher load range means a stiffer, stronger casing — which is more resistant to damage and better suited to carrying weight, at the cost of a firmer ride when empty.

On a truck that carries real weight, going up a load range is frequently the single best change available.

What to actually do

1. 1Be honest about the split. A truck that is 90% highway should be shod for highway, with a good spare.
2. 2A truck that spends real time on caliche should be on an all-terrain with an appropriate load range.
3. 3Match load range to the heaviest load you actually carry, not the average.
4. 4Adjust pressure for the load, every time it changes.
5. 5Rotate on schedule — dual-duty vehicles wear unevenly and rotation is what recovers the mileage.
