all you have to do is pull the centre cap out(where the S is) undo the nut behind it and get the wheel off.
when you undo the nut dont use the steering lock to jam the wheel, in can f**k it, try a breaker bar and hit it with a hammer to crack it, you may also need a steering wheel puller to get the wheel off the colum, DONT hit the end of the colum with a hammer, i believe like most other cars its age it has a collapsable steering colum designed to collapse under impact, if it collapse's you need a new steering colum.
