To make all of your RV experiences safer and more enjoyable, it is essential that you understand your RV tires. Ozone in the air and UV rays from the sun shorten the life of your tires.
It is not uncommon to see RV tires with low mileage
and plenty of tread that are ruined by the damaging effects of
the ozone and UV rays. Ozone in the air causes tires to dry rot
and deteriorate and UV rays from the sun make it happen quicker.
This is especially true of the tires sidewall. Inspect your
tires for checking or cracks in the sidewalls. If you notice
any damage have them inspected by a professional. There are
basically two ways to protect your tires from these elements.
Keep them covered with covers that will block out the sunlight
when not in use, or for long-term storage remove the tires and
store them in a cool dry place away from the sunlight. I also
recommend that you place something like a piece of wood between
the ground and the tires. Be sure that whatever you use is
larger then the footprint of the tire.
