Tires for pine duff, clay, gravel and salt
The tire decision here is unusual because two agencies write limits. On wildlife management areas the total wheel and tire radius must stay under 17 inches, ATV tires must be no larger than 26 by 12 and UTV tires no larger than 27 by 12, and both are capped at a one-inch lug height and 12 psi. On the national forest, trail tires may not exceed a one-inch lug depth. Farm treads in R1, R2 and R4 patterns are prohibited on state ground.
For a highway-legal truck the real questions are wet grip on red clay, sidewall protection on chert and gravel, and how the compound handles months of heat. Salt air on the coast road asks questions of the wheels rather than the rubber.
