I've only had my L322 about 6 weeks or so but I've already had a flat tire, imagine my shock when I couldn't remove one of the wheel nuts. It turned out that the wheel nuts have an outer stainless steel cladding and this had been damaged preventing the wheel brace from fitting. I've never seen this type of wheel nut before and can't believe Land Rover used them on the Range Rover. I was lucky, I managed to get to a Canadian Tire store and buy an over sized socket to remove the damaged nut. Since then I've replaced the street tires with a set of 5 Goodyear DuraTrac tires. Talking to the tire store manager he told me that my problem was a common one, that several other car brands use the same type nuts as well, that he often has problems with customers cars having distorted nuts. He said the problem is that water can get under the cladding and cause rust that in turn distorts the cladding. Not wanting to get stuck off road with a flat tire or damaged wheel that I could not replace I've replaced all my wheel nuts with new replacements that do not have cladding. I would suggest you do the same if you don't want to end up stuck with a flat that can't be replaced.
