Tire knowledge can be broken into several categories such as, inspection, DOT date codes, load ranges, sizes, care/cleaning, determining and measuring air pressure, and storage.In order to determine the correct inflation pressure for a motorhome’s tires, you need to know the size and load range of tires installed on the coach.That info is shown here on the sidewall of the tire. Tires can fail for a variety of reasons such as UV/ozone damage, age, road hazards, underinflation and overloading.So, if you are interested in being a good steward of your tires, perform a visual inspection on a monthly basis and before each trip.
Sidewall cracking can be caused by many factors such as UV damage, improper cleaning chemicals and improper use of tire dressings that contain petroleum distillates, as well as due to environmental ozone and inactivity/improper storage.
If you allow tires that are already 1 or 2 years old due to sitting in a warehouse to be installed on your motorhome, you have basically bought tires that are already 10-20 percent used up in terms of their useful life.
With the expense of tires, that is a costly mistake that can be avoided.
It is rare for motorhome tires to “wear out” from mileage, but it is still a good idea to check each tire for proper tread depth.
Most states consider 2â„32-inch as the very bottom of acceptable for tread depth, but on heavy vehicles with a gross vehicle weight rating (gvwr) of more than 10,000 pounds, many states require replacement at 4â„32-inch on the front axle (steer) tires.
Tires are made to support a maximum specified load at a given tire pressure and it is important to maintain that pressure in order to achieve the best tire life and ride/handling of your motorhome.
