When one dual fails, the tire beside it carried the load
A blown tire on a dual pair is the obvious problem. The less obvious one is the tire next to it.
From the moment the first tire lost pressure until the unit stopped, its partner was carrying the weight of both. Depending on how long the driver ran before noticing, that could be a few hundred yards or several miles of a single tire doing a double job, loaded and at highway speed.
A tire treated like that can look perfectly fine afterwards. The damage, if there is any, is inside: heat in the sidewall, stress in the structure. It may run for months. It may also fail on the next long leg, in the same position, and the second call will be blamed on bad luck.
Ask about the partner on every dual call
When the technician replaces the failed tire, ask for the mate to be inspected too, and tell them honestly how far the unit ran after the driver first felt something. That distance is what decides whether the partner is likely to be sound.
If there is real doubt, replacing both is usually cheaper than a second roadside call. A pair also runs better matched, since two tires of different wear and diameter on one dual end up sharing the load unevenly.
What to have ready
The location and direction of travel, which interstate, the tire size and position, whether the unit is loaded, and a number that will answer. The national roadside assistance page has the full list. Payment and authorization go faster on a fleet account, and a wheel damaged in the failure can go to wheel refurbishing here.
