Cheap and tires are two things that should not be used in the same sentence. I run azenis tires, the steel belt runs around the side wall and is extra stiff, hard as a rock, low rolling resistance, really good stability, and is either z or w? rated, whatever higher than z is... The tread compound is pretty grippy because its an import Road race tire with normal tread. Mine are 22" tall on a 15X7
