RV tire blowouts are dangerous. Most are preventable with correct pressure, load, age management, and inspection.
Underinflated tires flex excessively, generating heat. Heat weakens the rubber and can lead to blowout. Check pressure when cold before every trip. Use the tire load table—not the sidewall max.
Exceeding the tire's load capacity at a given pressure causes the same heat problem. Weigh your trailer loaded. Ensure total weight is within GVWR.
Tires age even when not used. Many experts recommend replacing RV tires at 5–7 years regardless of tread depth. Check the DOT date code on the sidewall. Cover or shield tires when stored.
Inspect for cuts, bulges, and embedded objects. Replace damaged tires. Uneven wear can indicate alignment issues.
Yes. ST (Special Trailer) tires are designed for trailer use—stiffer sidewalls, different load ratings.
Yes. A TPMS alerts you to pressure loss and temperature rise before a blowout.
Don't brake hard. Ease off the throttle, maintain steering, and pull over when safe.
