Inner dual or outer dual makes a difference
On a dual wheel position, two tires share the load side by side. When one of them fails, the most useful thing a driver can report is which one: the outer tire that can be seen from the road, or the inner tire tucked behind it.
It matters for three reasons.
What the technician brings. Changing an inner dual means removing the outer wheel first. That takes different time and sometimes different equipment, and it helps to know before the service truck leaves.
What else may be damaged. When one tire of a pair goes flat, its partner suddenly carries the whole load for that position. A driver who keeps going on a failed inner dual is overloading the outer one, which is how a single failure becomes two.
What caused it. Inner duals are harder to inspect and are more likely to have been running low unnoticed. A failed inner dual is a hint that pressure checks are not reaching the inside tires.
What to tell the store
The axle and side, whether it is inner or outer, the tire size if it can be read, and where the unit is. If the driver is not sure which tire went, saying so is better than a guess.
What is covered
Commercial units: tractors, trailers, straight trucks and equipment. Washington carries all nine Purcell tire categories, so the right replacement is more likely to be on hand.
Authorization is settled in advance on a fleet account. A tire that needs balancing once it is fitted is handled through tire and wheel balancing here, and equipment tires through OTR services.
