WIM is Wheels in Motion, a company that specialises in sorting your geometry, and tyres, and I think lots of other stuff :D
many members have been to WIM to have their Geometry checked and adjusted and if you have uneven wear, you need Wim'ing
its unusual the patterns of tyre wear we experience, its a known fact the IS standard set up has given many owners premature tyre wear, I had 18's on my car originally and they wore evenly the whole time on the car, admittedly only for about 6 months, but when I went back to 17's my inner edges on the front wore quickly and had to be replaced, I have budget tyres on the fronts now and have had for a while and they appear to be wearing evenly, they have been on since Oct, and have done 9000 miles
