Can you cross rotate radial tires on a car like left to right Some people say that it could cause a blowout and some say otherwise.?

Unless the tires are directional (indicated by an arrow on the sidewall), radial tires can be cross rotated. On FWD vehicles the front tires are moved straight back and the rear tires are crossed to the front. On RWD vehicles the rear tires are moved straight to the front and the front tires are crossed to the rear.
