I have 235/45x17 tires on my e34, and after a year I see that my front tires have an uneven wear - they both wear about the same ammount on the inside. The car goes straight, have been changed everything that looked a bit suspicious on the front suspension and steering, the rear tire wear is even on the inside and on the outside.
The rims are Borbet 17" x 8J /20 (hope I wrote it right).

Is it normal? Any ideas?
