Tire tread height difference on AWD

[SmokingTires]

Hey guys,

I'm just curious what you guys would do. I have two brand new Blizzak WS-50 and two lightly used ones. The new ones are 12/32 and the used are 9/32. 1/8 total height difference, or .5% overall height difference.

I've been brainwashed to believe in what the automakers say, not if you can help it. However on the Evo, I worry a bit. I have seen Audi's with AWD wear tires to bigger differences in normal driving.


Will I be find putting these on there? If so, where should I put the newer ones so they get worn down first (front or rear bias)?

Thanks,
-Mike
