Maintaining tire health is one of the most important safety practices in RV travel. A tire blowout can cause serious damage, delays, or even accidents—so regular checks and care are essential. Here's how to keep your RV tires in top shape:
1. Check Tire Pressure Regularly- Use a reliable tire pressure gauge before every trip or travel day.
- Inflate tires to the manufacturer's recommended PSI, usually found on the RV's door sticker or tire sidewall.
- Remember: Tire pressure changes with temperature, so check when tires are cold.
- A TPMS gives real-time data on tire pressure and temperature while you drive.
- It alerts you to slow leaks, under-inflation, or overheating—potentially preventing a blowout.
- Look for cracks, cuts, bulges, uneven wear, and embedded debris.
- Check tread depth—if it's below 4/32", it's time to replace.
- Make sure valve stems aren't leaking or dry-rotted.
- Rotate tires according to manufacturer guidance or every 5,000–7,000 miles.
- Balancing helps ensure even wear and a smoother ride.
- UV rays and weather can dry out and degrade rubber over time.
- Use tire covers when parked for long periods, especially in sunny or hot areas.
- Know your GVWR (Gross Vehicle Weight Rating) and GAWR (Gross Axle Weight Rating).
- Overloaded tires are more prone to blowouts and excessive heat buildup.
- Even if tread looks good, tires typically have a 5–7 year lifespan.
- Check the DOT code on the sidewall to find the manufacture date (last four digits = week and year).
- Ensure your tires are rated for the weight and type of your motorhome, trailer, or camper.
- ST (Special Trailer) tires are made for trailers, while LT (Light Truck) or commercial-grade tires are often used on motorhomes.
- If removing tires during off-season storage, keep them in a cool, dry, and dark environment.
- Store vertically, not stacked flat, and avoid placing them directly on concrete.
- Make sure your spare tire is inflated and undamaged.
- Keep a lug wrench, jack, torque wrench, and repair kit onboard for emergencies.
