I notice your rims are clean, rust-free, and are being assembled and inflated in a safe environment. I'm going to assume you're also using a safety cage during the inflation process? A wheel that's been sitting on a derelict truck half-buried in a mudhole for 10 years and then gets some air put to it to inflate a half-flat tire is the one that can get deadly, no matter what the design might be. I've seen a few idiots pull a stunt like that and get away with it, but the law of averages will eventually catch up to them.
