Just picked up a set of AT3's myself. I went with the blackwall, looks so much cleaner.

You're gonna love the tires! Smooth ride and almost inaudible on the highway!

 

The AT3's have been on for a few days now......blackwall out. Looks great! And indeed, very quiet and smoothe compared to the KO's. The only issue I have now is that a couple of the old wheel weights were a bitch to take off the rims and the effort by the tire shop put a couple of nipples on the edge of the chrome cladding that is on the face of the rim. Tried banging it back flat but it just looks a bit rough now. Any suggestions?

 

I'd keep the white letters out. Classic look and never goes out of style.

 

Blackwall out is the only way to go today.
