TIRE AIR PRESSURE……
…is probably one of the easiest things to forget. I always stress to my customers when they are picking up their new or used RV the importance of checking tire pressure. Sunlight alone does enough damage, but add under-inflated tires to the equation? That is definitely scary.
I have seen the damage done when tires blow out. Some folks get lucky, but when they don’t, damage can run in the thousands of dollars. What a sad way to start or end a trip! Now granted, not all tire damage is done by incorrect tire inflation pressure. Road hazards, over loaded RVs and old tires are some of the other causes of blowouts.
If you are not sure what pressure to inflate your tires, check on the tire sidewalls. The manufacturer will have the recommended tire pressure there for the maximum load. Most units provide the recommended tire pressure and size on the exterior tag of the RV. Of course they are

assuming you will not overload your rig. You must take into account the average life span for a RV tire is five years (that is, if you keep them covered up and out of the sun). Severe weather checking or cracks in the sidewalls can also cause a blow out or flat. In addition, you need to inspect your tires for any road hazard damage, don’t take chances! If you are not sure, get your tires inspected by a qualified tire center or store.
I am speaking from experience. I thought I could get six years out of my tires, buy was I so wrong! I didn’t have a blowout, but it was close. We were on our way up to the U.P. of Michigan, and a car that was passing us waved and pointed back towards our fifth wheel. I immediately pulled over, and I was sure glad I did. The driver side tire was smoking, almost ready to blow. I had to let it cool down even before I could take it off and replace it with our spare. We limped into a state park, and the next day was consumed by purchasing and installing a new set of tires. Definitely something I didn’t want to do on our already too short of a vacation trip!

I recommend keeping your tires covered up and out of the sun when not traveling, and checking your tire pressure on your RV along with your tow vehicle before every trip. Some of the problems associated with RVs not pulling very well are contributed to incorrect tire pressure on the tow vehicle itself. If you are not sure how much your RV weighs after you loaded it up, take it over a truck scale, which are usually around ten bucks. You will probably be surprised how much your RV weighs loaded after it is up for a trip.
Unfortunately, I do not currently travel enough to wear the tread out on my RV tires, but you can bet I will purchase new ones at the five year mark. Unless of course, they are damaged before then. And every RVer should not be without a tire gauge. Safe travels!
