Motorhome tires are usually sturdy and tough. The tread is intended to cover many miles with minimal wear and tear. The most significant factor nonetheless in avoiding blowouts is the age of the tire. Deadly blowouts at high speeds are repeatedly caused by possessing tires that are too old.
You could see the amount of tread on your tire and consider that the tire is in wonderful condition where as it is actually in an exceedingly risky state and on the point of blowing out. The most hazardous thing about this is that as Motorhome tires are normally changed as sets or at least as axle sets then if you have one blowout it is extremely likely that you will have more within a very short time. When you are thinking about purchasing a used Motorhome at an auction, from a supplier or a private vendor then it essential that you inspect the tires thoroughly. If the tires have a decent amount of tread then this will undoubtedly be pointed out by the vendor or the dealer, this is not the most significant thing to consider here.
Tires on an Rv need to be changed every seven years. Because of exposure to the sunlight and the elements, the side walls of a tire will tend to lose its natural oils. Small cracks will start to materialize to start with and these will shortly convert into larger ones until finally your tire blows out on you.
If you do not have your tires inflated enough then this can be an additional reason for a blowout to occur. Certain owners wanting a ‘soft ride’ will intentionally run their Motorhome on lower tire pressures, this will just generate a load of heat and will cause major problems.
Here are some photos of a blown out tire to show you the gravity of the effect:
Verify the tires of a vehicle with attention to detail by searching for the small cracks in the side wall, then attempt to locate the DOT number. The DOT numbers should be somewhere on the side wall of the tire and will consist of a sequence of numbers and letters. It is normally in the format of DOT xxxxxxxx0393, the last digits will correspond to the month and the the year of manufacture. In this example the tyre would have been made in March 1993. Scary if you are recommended to change every 7 years regardless of the mileage of the tire.
A blowout on the freeway can be truly serious. If it’s a front tyre it has the result of slamming the brakes on one front wheel only. The possibly of striking the crash barrier and maybe rolling over is high. Should you be ill-fated enough to have a front blowout you will need to struggle with the steering wheel to control the Rv and steer it to the side of the road.
Your steering is not affected if the blow out is on one of the rear wheels. If you have twin rear wheels and the blowout occurs between the two tires on one side of the Rv, The blast from the one tyre can often kiss the other and cause that to go as well. If the blowout is on the outer wall of a tire then this too puts your bodywork at risk.
With a blowout occurring at the top of a wheel rotation the damage from the blast can literally rip away any fiberglass bodywork. If you were to have a blowout on your vehicle then the best place to have it (if there can be a best place) would be on the inside wall of one of the rear tires.
As an ending note, Unless you are really athletic and have all the right gear, don’t try changing the RV wheel by hand. Always call the insurance or rescue truck as these are heavy duty wheels and need qualified and experienced people to handle them.
