The agency said new research indicates that 74 percent of all 15-passenger vans in the United States were likely to have "significantly mis-inflated" tires, compared with 39 percent of cars, the Detroit News reported Friday.
The NHTSA said improperly inflated tires can change handling characteristics and increase the likelihood of a rollover.
"The risks associated with 15-passenger vans can be minimized if users take some basic safety precautions," said NHTSA administrator Dr. Jeffrey Runge.
