I believe you are referring to the MSA Offroad M44 Cannon Beadlock. This is a true beadlock wheel that includes a bolt-on center cap with a removable star and MSA logo cast into the wheel 1. The wheel is available in two sizes: 14x7 and 15x7 1. The wheel is designed with a concave modern round hole design and a forged 6061-T6 beadlock ring 2. The wheel requires aftermarket lug nuts and valve stem
