What is the first thing to do when a tire lets go?

Keep both hands on the wheel and hold the truck straight — do not brake hard and do not yank the wheel.

Ease off the throttle gradually

Let the truck slow on its own before you touch the brake pedal

A hard brake on a blown tire can pull the truck sideways

How do you get off the road safely?

Signal, check mirrors, and move to the right shoulder or the nearest wide spot — an exit ramp if one is close.

Stop as far right as the shoulder allows, wheels straight

Choose flat, firm ground — a jack cannot work safely on a soft or sloped shoulder

If the shoulder is narrow, a well-lit parking area or stop lot near the nearest exit is the safer stop

What do you do once you are stopped?

Set the parking brake, turn on the four-way flashers, and put out your warning triangles.

Triangles: one near the rear of the trailer, one further back, one furthest back — spaced so traffic sees the warning early

Wear a reflective vest before you walk the trailer, especially at night

Stay on the shoulder side of the truck — never work between the truck and the travel lane

How do you check the damage?

Walk the full tire set: the blown tire, its dual mate, and the tires next to it.

A blown tire often damages its mate — the mate carried double load while you slowed down

Check for rubber debris wrapped at the hub, a damaged rim, and a torn mudflap or air line

Note which position failed: steer, drive, or trailer — the service truck needs that before it rolls

Can you drive to the next exit on it?

A blown steer tire: no. A single blown drive or trailer tire: only at low speed, only if the mate is holding air, and only to a safe stop — never to finish the run.

Running on the rim destroys the rim and turns a tire job into a tire-plus-rim job

Shredded rubber can take out air lines, lights, and mudflaps as it comes off

Tires are the #1 roadside event for tractors — 53.5% of all road calls (TMC, via FleetNet America) — service trucks are set up for exactly this

What do you tell the service dispatcher?

Your exact location: the highway you're on, direction, and the nearest exit or mile marker.

Tire position (steer / drive / trailer, and which side)

Tire size — read off the sidewall if you can do it safely

Loaded or empty, and whether the rim looks damaged
