Just a week ago I was deep in the W.A. bush and destroyed a tire on my BT50, to my horror I discovered that my wheel nut spanner did not fit on the nuts, I was lucky not to be on my own, so Kim and Linc. helped me, it was very difficult to get the wheel nuts off. After the trip I went to Kalgoorlie Mazda, they could not help me, and they sent me to Tyrepower down the road. The tyrepower manager told me that I was not the first one with this problem, the original wheel nuts got an alu.capping, and after a certain time they swell and you can't get a spanner on the nuts, so I had to buy 24 after-market wheel nuts from Tyrepower. This is good to be aware of. Cheers, Hermann.
