The tires were initially designed for use on regional delivery trucks and were not properly tested for RVs. Goodyear G159 tires were not designed to carry the loads that big RVs haul; overloading tires can lead to tire failure.
According to Goodyear's "Recreational Vehicle Tire and Care Guide," "Overloading your tires carries serious consequences for passengers and your RV. Too much weight can cause problems such as: RV's suspension system failure, brake failure, shock absorber damage, handling and steering problems, irregular tire wear and possible tire failure." However, the RV manufacturers put the Goodyear G159 tires on their vehicles at Goodyear's recommendation, even though Goodyear does not have the data to show that the tires are safe for RVs.
Both Fleetwood and Monaco have carried out some form of recall on the tires but there are still RVs on the road with those tires on them.
Goodyear has been involved in other tire recalls. In 2001, the company replaced Load Range E and Wrangler LT tires after a 14-month investigation by the NHTSA. The investigation looked into reports of 86 accidents, including 18 fatalities. In 1996, the tire-maker began putting extra nylon in the tires. That move came in response to a discovery that some tires were prone to failure at high speeds or high temperatures.
Goodyear was also in trouble for what was known as a "silent recall," fixing tires with tread problems when customers complained but not ever making a recall publicly known. The silent recall was associated with the Load Range E tires that are used on pickup trucks, SUVs, vans, RVs and ambulances.
If you have an RV, check to make sure that the tires are not Goodyear tires, model number G159 275/70 22.5.
