As a businessman, Sean “P. Diddy” Combs still gets mad props. (Do the kids still say that?) But as a brand, Sean John might be wearing a bit thin. Already a hip-hop musician and “entertainment entrepreneur,” the former limo driver is now branching out into the auto-parts business, selling custom rims for luxe SUVs, sports trucks and cushy sedans. There’s no doubt it fits well with the urban culture—spinning rims that run $700-$3,000 per wheel add extra “bling” to your Escalade.
