Tire Management That Actually Prevents Roadside Failures
Tires cause more roadside calls than anything else, and most failures were preventable. What to check and how often.
Tires are the single largest cause of roadside service calls in heavy trucking, and the large majority of failures were preventable with information the fleet already had access to.
Pressure is nearly everything
An underinflated tire flexes more than it was designed to. Flexing generates heat. Heat degrades the bond between the belts and the rubber. The tire separates, usually at speed, usually in the summer.
That chain is why a tire that looked fine yesterday comes apart today. It was not fine yesterday — it had simply not finished failing.
Check cold, and check the inside duals
- Cold means before running, not after a stop.
- Inside duals are the ones that get skipped and the ones that fail.
- A gauge, not a hammer. A tire thump tells you a tire is not flat; it does not tell you it is correctly inflated.
- Mismatched duals put one tire dragging the other, which destroys both.
- Valve caps matter — they are the secondary seal.
What to look at beyond pressure
- Tread depth, with steer axle minimums stricter than the others.
- Sidewall cuts, bulges and exposed cord — any of which is an out-of-service defect.
- Irregular wear patterns, which point at alignment, suspension or inflation problems rather than at the tire.
- Casing condition, if you are running a retread programme.
- Age and date codes on trailer tires, which frequently sit far longer than they run.
- Wheel fasteners, because a wheel-off event is the worst outcome on this list.
Retreads and casings
A well-managed retread programme is sound economics, and the whole of it depends on casing management — running the correct pressure so the casing survives to be retreaded, and pulling tires before the casing is damaged rather than after.
When a blowout happens
Hold the wheel, ease off, do not brake hard, and let it slow before steering gently to the shoulder. Then get well clear of the traffic side of the truck before doing anything else.
