Start with the decision that changes the outcome
Truck tire lifespan depends on axle position, load, inflation discipline, alignment, route severity, and whether the casing is protected for retread value.
There is no honest single-mileage answer for fleets or owner-operators. A steer tire in steady highway service ages differently than a drive tire in regional stop-and-go work.
How to narrow the field quickly
Use wear pattern, heat exposure, tread depth, and service role to judge the real timeline. That produces a better replacement plan than chasing a generic mileage promise.
Best next move
When the service window is tightening, move into the exact commercial size page and quote path so the replacement decision happens before downtime turns urgent.
