Many commercially available tire dressings are aimed specifically at the automotive industry, where tires quickly wear out in a few years due to tread wear.Motorhome tires usually fail from sidewall damage, overloading/underinflation or age.For 95 percent of motorhome owners, tires will be replaced from age or sidewall cracking long before the tread is worn out, but tread depth is still part of a good tire inspection.In addition to looking for obvious problems such as road hazard damage or bulges, you need to also carefully look for sidewall cracking.So be careful and don’t assume that all products sold at the local auto parts store are suitable.

Most states consider 2⁄32-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 4⁄32-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.The first step in this process is determining the load range of the tires and then obtaining the load/inflation chart from the tire manufacturer.Most tire manufacturers state that 10 years is the absolute maximum that a tire should be in use, as long as it has been properly maintained, and preferably covered while in storage.This time limit is from the date of manufacture of the tire, not the date you installed them or purchased the coach.
