On a cast wheel, that is somewhat common for the companies that have really low prices on them. Ive had a set break open on me like that as well. Low profile tires done help at all. I had a set of 225-35-18 tires on some boss wheels, and had the same issue. Broke open like it was made of ceramic or something.
On a billet wheel, thats down right awfull.
