I have no idea whether many or any of us here use or own RVs or motorhomes. It seems, however, that at least one tire manufacturer for many years is likely to have been concealing major defects resulting in highway speed tire failure, an extremely dangerous situation. I won't name the manufacturer here on the DBR. But,
Jalopnik has the story.
So check your vehicle for these tires. If you have them, change them out! I understand that these tires are now old--an even better reason to get rid of them.
