Everyone knows that tire health is important on the family car, but how about your RV? At over $100 for just a single tire alone (not counting rims and installation), proper tire care is vital to ensure that your RV remains safe for everybody on board. Obviously, without tires you wouldn’t exactly be driving very far, but what can you do to make sure your RV doesn’t wind up in the junkyard?


1. Know Your Tire Pressure

Make sure that you’re using an accurate tire pressure gauge to make sure your tires are properly inflated.  Often, people might forget to just check their tire pressure and might wind up with a flat that seemingly comes out of nowhere.  In addition to possibly causing sudden flat tires, tires that are under-inflated can cause significantly more tread wear than properly inflated tires.

Aside from that, be mindful of temperature changes.  Air particles will expand when they reach higher temperatures, causing them to take up more space and apply more air pressure to the inside of your tires.  Make sure that your air pressure is measured on cold tires to ensure as much accuracy as possible.


2. Check for Tread Wear

Take a look for any uneven wear and cracks in the sidewall of your tire. While it’s basically unavoidable,  and nothing to get too worked up over at first.  You should look at replacing your tires if you have cracks in your tires that are any deeper than 2/32″.

The tread of a tire is the raised outer portion of a tire, which makes contact with the road.  Tires should be replaced when the treads are any less than 6/32″ deep.  An easy way to test this is by taking a penny and placing it between the tread ribs with Lincoln’s head facing downwards.  If you can see his entire head at any location, then your tire should be replaced.

3. Monitor Weight Distribution

When possible, try to make sure that weight throughout your RV is distributed as evenly as possible.  The best way to weigh your RV is through wheel position weighing, which is available at most RV stops.  The advantage over this over traditional weighing is that you know how much weight is on each tire, and it becomes easier to balance your weight accordingly.  Traditional truck scales will give you the weight for the entire RV, which can end up giving you a false sense of security and cause permanent damage to your tires as a result.
