The change will not affect Saturday qualifying.
NASCAR informed teams of the switch Friday night, after a second consecutive day of soaring practice speeds at the newly repaved track. Goodyear says the higher speeds caused increased left-side tire temperatures, leading the company to change its tire recommendation.
Drivers routinely exceeded 200 miles per hour in practice, with Greg Biffle topping out with a lap of over 204 on Friday.
