Heat makes alignment worth more, not less
Alignment is sold on tire mileage, and in a hot climate that argument gets stronger for a reason that is not obvious.
A misaligned tire is being dragged slightly sideways rather than rolling cleanly, and dragging generates heat. In a cool climate the tire sheds it. On hot pavement in summer the tire is already running near the upper end of what it was designed for, and the additional heat from the misalignment has less margin to work within.
The result is that the same geometry error costs more here than it would somewhere temperate. It shows up as tires that wear fast, and occasionally as tires that fail rather than wear.
Which is also why a fleet that runs this corridor in summer should treat alignment as a seasonal priority rather than a year-round average. Measured before summer, a unit goes into the hard months with its margin intact.
What gets measured
Steer axle angles, drive axle alignment, and the relationship between them. Where the readings point at a worn or bent component rather than an adjustment, you get told.
The national heavy-duty truck alignment page covers the symptoms and what a correction protects.
The trailer
A trailer that tracks crooked drags whatever pulls it, which is the same heat argument applied to a different end of the combination. Trailer alignment is offered at this store.
Getting it scheduled
Alignment needs the rack, which means it is the work that cannot come to your yard even though mobile service covers most of the rest.
The practical answer is to attach it to the units that are coming in anyway, and to measure before summer rather than after somebody notices the tire bill.
