Every RV forum preaches the same gospel: replace all your tires every 5-7 years regardless of tread wear. Tire dealers love this advice because it generates massive profits—a set of six RV tires runs $1,800-2,400. But here’s the shocking truth: properly stored and maintained RV tires regularly last 10-12 years without incident. The tire industry created this myth to boost sales, and RVers accepted it as gospel.
The real enemy isn’t age—it’s UV exposure and underinflation. A tire engineer I met at an RV show revealed that 90% of RV tire failures happen because owners run them underinflated or park in direct sunlight for months. A $15 tire pressure monitoring system and $40 tire covers will extend tire life far beyond the arbitrary 5-year replacement schedule that dealers push.
Here’s what actually matters:
- Check pressure monthly (underinflation kills tires in months, not years)
- Use tire covers whenever parked more than a week
- Inspect for cracking and bulges—visual signs matter more than age
- Keep a detailed log of pressure readings to spot slow leaks
The most expensive lesson? One couple I know replaced perfectly good 4-year-old tires for $2,100 because their dealer insisted they were “getting dangerous.” Those old tires could have safely lasted another 5-6 years with proper care. Meanwhile, I’ve seen 8-year-old tires with perfect sidewalls and plenty of tread that dealers claim are “death traps” simply because of their age.
