The tests found some tire claims are too optimistic.
Consumer Reports says a Kumho tire with a 75,000 mile warranty should only last around 55,000 miles; a Continental tire with a 90,000 mile warranty projects a tread life of 60,000 miles; and a Nokian tire with a 80,000 warranty will wear out around 35,000 miles.
The tire tests also revealed some tires will exceed their manufacturer warranties.
"Michelin was a standout," said Rechtin. "The three models we tested all met or exceeded their mileage warranty and came in with a projected tread life of 80-thousand miles or more."
The longest lasting tires in the tests are the Pirelli P4 Four Seasons Plus. Pirelli claims they will last 90,000 miles. Consumer Reports estimates they will go 100,000 miles.
