Things I have learned about tires…

Reading through the many blogs one becomes painfully aware of the fact that between you a good time is where the rubber meets the road… it is your TIRES! Tire blowouts are apparently no fun at all and can cause a tremendous amount of damage to the underside of your trailer or rig when they occur.  So what did I learn form reading all the blogs that talk about their experience with blowouts?

Three key things:

  • Learn how to determine the age of your tires
  • Install a Tire Monitoring System or develop a plan to always check tire pressure
  • know what to do if you have a blowout before you have one

Why do I need to know the age of our tires? Well the older the tires are is one of the key factors that contributes to tires failing. Blog wisdom suggests that If your tires are more than seven years old they need to be replaced. So how do we know how old they are?  We need to know what the DOT number is on the tires (Easy to remember if you think DOT=date of tire :) DOT numbers are usually on the inside sidewalls so use a flashlight to find them. The last three to four digits of the DOT number tell us how old the tire is. If the DOT has three numbers they are older tires and the first two tell us the week of the year that the tire was made while the last number tells us the year it was made. Newer tires have four DOT numbers. Like before the first two numbers are the week it was made and the last two tell us the year. How useful is this! I was looking a a 2005 Winnebago Journey recently and was told the tires were less than two years old.  After looking at the DOT numbers on the tires and seeing 2104 I knew I was being told untruths too since the DOT number told me the tires were made on the 21st week of the year 2004.  This small untruth meant that I would need to spend two to three thousand dollars to replace tires on top of the price of the rig.  Also, it suggested there may be more untruths being told to me about this rig … needless to say I didn’t buy it.

Also, I plan to install a PressurePro Tire Monitoring System on my future home as well.  Again the blog wisdom suggests that no RV should be without a tire pressure monitoring system.  And from what I have read the PressurePro System is one of the best. It consists of a monitor and tire monitoring sensors.  The sensors screw onto the tire valve stems in place of the the valve caps. This allows us to always see the tire pressures before traveling and while traveling on the road we could be alerted when tires experience low pressure helping us avoid costly and dangerous tire blowouts. A must have in my opinion…

… and a last item about tires that is good to know is to better understand what to do if you experience a blowout…


  1. Excellent information as always!

    I like the idea that asking for the tire age might give one insight to the truth telling about other aspects of the rig.

    Thanks for posting all of this.

    By the way have you gotten the "How to buy a Used RV" book? I've been thinking about buying it. $27.00 is a small investment if it helps in any way.

  2. I haven't really looked at buying any buying any books other than spending the big bucks for the rv rating cd from There is so much free information on the web that I will mostly rely on from here on out...

  3. Yes... we learned about tire dating on our last rig the hard way (the tires were 13 years old!) and we also now run a tire pressure monitoring system on this rig too. (Hopkins from Camping World)
