A Few Thoughts on Tires


I want to take a few moments to offer some public service info on tires.  I am not a tire expert.  I have no great amount of tire information to offer, but I do know where to go for expert advice and that’s to go to people who make tires.

While we were coming at Eagle’s Landing RV Park we met a lovely couple and had a nice chat with them.  The sum of all our conversation focussed on one factor.  They are afraid to take their 5th wheel trailer anywhere because they “keep having blowouts!”  It was an interesting conversation but there’s one thing for sure — you really can’t give tire advice to RV park neighbors.

It’s pretty much a natural phenomenon;  guys are territorial about their own knowledge.  And guys hate to be “told” stuff.  Pretty much any stuff.

There are lots of reasons for tire failure. Most of them are NOT bad tires.  Inflation problems, maintenance neglect, overloading, and all sorts of other factors affect tire performance and failure.  Even the number of axles under your rig will affect tire life.  The more axles the more your tires will scrub sideways when maneuvering instead of turning while rolling, causing extreme pressures on the sidewalls.

5th wheel axles 1It might be really cool when you see a really long RV go by, and you think “Wow, wouldn’t it be nice to have one of those!”  Don’t fool yourself.  In the same way that the expression, “Everything that glitters is not gold” is true, just because you see something you’ve never seen before does not mean it’s the best idea since sliced bread.  Sometimes the reason you don’t see certain things is because they don’t really work very well.

4521619_f520If you want a plushed out RV with all the bells and whistles you are talking about adding weight to your RV.  How much weight depends on how many toys.  The heavier your RV gets the more tires you need underneath it to carry all that weight.  On a motorhome you can add pairs of tires in the back on the same axle.  On a trailer you add axles with 1 tire on each side of the trailer.  And adding weight to the RV means adding additional axles.  The more axles the harder it is to turn your RV — harder in terms of space required to do so and harder in terms of the stresses transmitted to the tire sidewalls overtime you turn — whether a mild turn or a hard turn. tire bubble

Whatever RV you may have here are two resources you might want to check out.  I’m sure you can find additional information — most likely by other tire manufacturers.  But educate yourself about your tires.

And also — next time you go RV shopping — take what you learned about tires and factor that into your decision about what kind of RV to purchase.  Be informed.  Make better decisions.

Thanks for stopping by, and I”ll talk with you tomorrow.

  1. I suspect overloaded is often the culprit. People who think they can continue to put things in just because they still have space often have no idea what their rig weighs. Rather than trying to teach that neighbor something you might try casually telling him how much your rig weighs less than its GVWR then asking him how much his rig weighs. It likely will still make him defensive but might start him thinking.

    1. Linda — I’m sure you’re right on the weight topic. And frankly, most failures are customer caused. I stay away from ‘telling’ neighbors as much as possible. I tried to encourage him to get his rig weighed. harder to argue with numbers off the scale than a neighbor! And some people don’t want to be helped cuz they know it all. Surely we have both met that kind!!!!!!

    1. Dave,

      Whether under inflated, over weight, driven over obstacles — they are almost all owner induced problems as opposed to road hazard related problems, don’t you agree? Most of the times it’s we who create our biggest problems.

  2. Dave is 100% correct. Howard Payne at RV-Dreams.com gave me that advice, and it has saved my bacon after picking up a nail in a tire once. Also, people need to weigh by EACH INDIVIDUAL WHEEL through the RVSEF http://www.rvsafety.com, as it is very possible to be overweight on one tire, but not on that axle. A CAT scale won’t tell you that. I am heavy on my refrigerator tire, but not overweight. A great deal has been said about Goodyear Marathon 10 ply tires being ‘China-bombs’, but it is usually because they are overloaded….not because they are made in China. Once you weigh your rig, take an inventory of what is in it, and where. Redistribute and purge, if needed. Reweigh, if needed. After that, if an item comes in, know the weight and remove something to allow for the new item.
