Few events spike adrenaline like an RV tire blowout at highway speed. Knowing how to prevent an RV blowout—and exactly what to do during an RV tire blowout—can save your rig and your trip.
Why RV Tire Blowouts Happen
- Under-inflation → heat buildup and sidewall flex
- Overloading axles or exceeding GVWR/GAWR
- Aged tires (5–7 years), UV cracking, impact damage
- Sustained high speed and summer pavement temps
- Hidden alignment issues or bent axles (towables)

Blowout Prevention: The Big Four
- Correct PSI from Load Charts
Inflate by the actual axle/corner weights (CAT scale), not guesses. Use a TPMS to watch pressure and temperature in real time. - Stay Within Ratings
Confirm payload, GAWR, and GVWR; balance cargo for proper tongue/pin weight (TT 10–15%, 5er 15–25%). - Speed and Heat Management
Keep speeds moderate; heat kills tires. Pause more often in high heat to cool tires and brakes. - Age and Condition
Replace at 5–7 years from DOT date or earlier if sidewalls check, cords show, or wear is irregular.
What to Do During an RV Tire Blowout (Step-by-Step)
- Do not slam the brakes. Sudden braking can destabilize the rig.
- Stabilize with throttle. Gently apply throttle for 1–2 seconds to maintain forward stability and straighten the combination.
- Keep steering inputs small. Grip firmly; hold lane as the rig settles.
- Ease off the throttle. After stabilization, gently decelerate and signal to shoulder.
- Stop straight and secure. Hazard lights on, chock wheels on the good side if safe.
After the Blowout: Safe Recovery
- Inspect for collateral damage: wiring, brake lines, wheel wells, plumbing near the tire.
- Mount the spare only if safe space and proper tools exist. Otherwise, call roadside assistance.
- Replace in pairs on the same axle when practical; re-torque lugs after 25–50 miles.
Upgrades That Reduce Risk
- TPMS with temperature alerts
- Metal valve stems and balanced wheels
- Shock absorbers on towables to control hop and heat
- Alignment/camber correction if wear shows on one edge
Pre-Trip RV Tire Checklist
- Measure cold PSI before rolling
- Visual scan for nails, bulges, sidewall cracks
- Verify torque on lugs and check spare condition
- Reconfirm hitch/WDH or pin height for level towing
