Decided yesterday to rotate my tyres from to back and reverse. I managed to get the wheel nuts off with a bit of mucking around with different sockets, swapped wheels on one side and then tried to tighten the nuts. No way was I able to fit a socket that would tighten them. Looking at them showed all had rounded the edges. New nuts were required so calls to Repco, Supercheap etc came up with no results except advice to try a type place as they change wheel nuts often. Sure enough, my regular tyre place, Jax, had them at $3 each. I asked if they were genuine as I did not want them and was told it would cost me $500 for a set of genuine nuts. So $72 and another 2 hours later and a lot more descriptive adjectives of Mazda and Ford, I had all wheels rotated and 6 new solid nuts per wheel. I had to hammer a socket onto every nut to get it to bight enough to turn off.
The original nuts are a plain steel nut with a stainless steel cover which is what gives up under loosening and tightening. I cut one open to see.

Here are a couple more pics of the other nuts. I am just glad it did not happen on the open road as there is no way I could have tightened the nuts if I had to change a wheel.
