I just want to throw my 2 cents worth in.

I have (HAD) 20" Staggered with Atturos and they are the worst tire I have every had. They are so noisy, and hitting water on the road makes for a very slippery time. I have travelled on mud and the whole back end started to fishtale before the traction control took over (never had this with Michelins and I was only going 20 kph).

With the tread on them, it seems to be holding the car back, free rolling was limited.

Since the 20" rims/tires was killing the car (extra load killed the transfer case, another story), I switched back to the 17" with Michelins and couldnt believe the difference, you could hear no road noise unless on a really bad road.

Here in Australia, I could have paid a few hundred dollars more all up for Bridgestone Duelers which I think would have been a much better choice.

The only two good things about the Atturos is that (1) after about 7000km, no wear on them at all and (2) the chunky edges protect the rims if I accidently get too close to the gutter.
