The Proper Way To Check Tire Pressure On Your Motorhome

The Proper Way To Check Tire Pressure On Your Motorhome


Tires are the topic. Hi, I am Steve DuVal
from Thor Motor Coach. Before you hit the road, you make sure your tires are ready
to roll. So we’ve enlisted the expertise of doctor Tred to give us the ins and outs of
tires…Here he comes now. I’m Here…Hey, Dr. Trent thanks for being here, can’t
wait to get started but we need tires for this right? Of course we do…Well yours are rolling away…Oh Pythagoras! In order to check your tire pressure, you
need this. That particular gage goes up to 160 psi which means what Dr. Tred? Pounds per square inch. Have you ever taken a close look at a tire? That sidewall is chock-full of
information. Here, you can find the load rating, inflation pressure, speed rating, size, and even
when and where that tire was made. Some of that information can also be found
inside the coach. On this particular model it’s inside the door jam. Now it’s
important to remember to check your tires when they are cold, right Dr.
Tred? Factual! Gas expands when heat causes molecules to move faster. As heat energy is converted to kinetic energy, this means the volume of the gas increases more than the
volume of a solid or a liquid. however gases that are contained in a
fixed volume can NOT expand and so they increase the temperature and as a result
increased the tire pressure. Checking the pressure easy peasy. Remove the cap, put
the gauge on and here’s your readout remember maximum tire pressure and
recommended tire pressure are not the same. You want to go with ideal. On rear
dual wheels, to locate and check that inner tire too. If you need air, put some in
but do not over invite that tire. If you need to let some air out, you can, but never let air out of a hot tired you
could under inflate it. So what happens if you over or under inflate your tires
Dr. Tred? Improper inflation? Well, that would lead to all kinds of chaos, like dogs playing with cats. Peanutbutter not
going with Jelly, and, I will take over the world! What are you doing? You can’t say that. What if your grandma was
watching? I should smack you with this. Okay, I’ll explain this. Under-inflated
tires will build up excessive heat. Over inflation can reduce traction, braking,
handling, and cause uneven tire wear. You should check the air pressure every two
weeks or at least once a month before any major trip. Your tire pressure should
be checked every morning on long trips. As Dr. Tred said, you want to check your
tired when they are cold. Now a cold tire is one that has not been driven on
for at least three hours, not considered cold because it’s chilly outside. So it’s
important to check that pressure after but before you hit the road right Dr.
Tred? Exactlly! Properly inflated tires include improved handling, fuel economy, increased
life the tires, and it’s easily it’s a safety issue. Air pressur e supports the entire RV, so
proper inflation is important. Air pressure and load limit go hand in hand and you never want to exceed that load limit. Overlading makes the vehicle hard to drive and it can cause damage to your motorhome and again, it’s a safety issue. Fascinating stuff Dr. Tred. Science! you can let go.
