My IS200 has just been up on a ramp to have a tyre changed. The mechanic noticed that all 4 of the alloys have got a flat spot. Apparently this can be caused by going over a pot-hole/cattle-grid, etc at high speed. I don't recall ever doing this (I'm the only person to have driven the car). Lexus are now telling me I need to replace the alloys. I'm planning on challenging this, as I think they should last longer than 20k miles of normal use. Has anyone else ever experienced a similar problem?
Thanks.
