How to read a commercial truck tire size
Metric sizes like 295/75R22.5 and conventional sizes like 11R22.5 describe different sections and aspects. Copy the full string from the sidewall.
Include ply rating and whether the tire is steer, drive, trailer, or all-position. That keeps the quote aligned with what is on the truck today.
Cutting downtime with scheduled tire inspections
Start with what the tire is telling you.
Tread wear, sidewall condition, and pressure history all point to what is happening at the axle. Reading them well saves service calls.
What to look at first
- Uneven wear across the tread shoulders
- Cuts, cracks, or bulges on the sidewall
- Nails or foreign objects in the tread
- Pressure loss beyond normal daily variance
Start with what the tire is telling you.
If the tire is losing pressure fast, has sidewall damage, or is worn below legal depth, request service before continuing the route.
“The cheapest tire is the one you don’t have to replace on the shoulder of the interstate.”
Preventive service almost always costs less than emergency service. A quick inspection at the yard can move a tire replacement from an unplanned event to a scheduled one.
