Hi,
I went to the mechanic yesterday, I have a 2008 Is 250. The issues they say the car has is the front camber, apparently is damaged and this is what is causing the issue of uneven wear on the tires. there might be other things affecting as well but this is what they recommended I should do first ( I went to have my car aligned but they said it was already aligned they even showed me the results the computer gave them)
