RV Tire Problems – How Sun Damage & Flat Spots Destroy Your RV Tires

Old RV tires are an accident just waiting to happen!  




Here’s why…


RV Tire Problem #1: Sun Damage

RV tires that sit in storage for long periods become weak — especially if they’ve been exposed to the sun much of that time.  Long periods of storage under direct sunlight can lead to damage that you can’t even see. 

Even though they may look fine, at highway speeds your RV tires can disintegrate and cause an accident.  That’s right, your trip could be ruined when a seemingly good RV tire explodes without warning. 

So, if your RV spends much of its time in storage or parked for long periods of time, always check the tires closely each time before you head out on the road. Here’s what to look for.

By storing your RV indoors, or at least protecting the tires and other sun-sensitive surfaces with covers, you can prolong the life and luster of your RV.  This not only makes your RV safer, but helps to retain more of its original value as well.

Here are some tips from Goodyear regarding RV tires:

Ideally, a vehicle in storage should be placed on blocks to remove all weight from the tires. If the vehicle cannot be put on blocks, follow these steps for tire protection:

  • Completely unload the vehicle so that minimum weight will be placed on the tires
  • Inflate tires to recommended operating pressure plus 25%. Ensure that the rim manufacturer’s inflation capacity is not exceeded
  • Be sure the storage surface is firm, clean, well drained and reasonably level
  • Avoid moving the vehicle during extremely cold weather
  • Move the vehicle at least every three months to prevent ozone cracking in the tire bulge area, as well as "flat-spotting" from the prolonged strain of sidewall and tread deflection
  • Adjust inflation before putting the vehicle back into service


RV Tire Problem #2: Flat Spotting 


Another RV tire problem associated with longterm storage is flat spotting

Wonder what that rumbling noise is as you head out?  Your tires have become less than round from sitting in one spot for too long. 

To avoid this, keep your RV tires properly inflated — even when in storage. 

Your best bet is to take your RV for a ride every month to keep the tires in good shape.

Think twice before heading out on RV tires that have been out in the sun for 5 years or more.  You could be setting yourself up for a terrible accident.
