Way too late on this one, but if anyone is in the PDX area I really like working with A-N-T Tire and Wheel. I've brought them some weird problems on my Ranger, Blazer and other vehicles I've owned. Reasonable rates too.

I started going to them because they've always got old Saab race cars in the parking lot, and when the Oregon Trail rally is in town you see built Fiestas on trailers in there. They know what they're doing, for sure - although they're probably not a great "drop in" shop. They are apparently the only people that could balance a set of Goodyear Duratracs on my Ranger (Goodyear ****ed up the install so bad they forgot to add adequate air pressure, didn't even try a balance, Les Schwab said they balanced them but they weren't) and they've done front-end rebuilds on a few of my vehicles and have never tried to sell me on anything.
For drop ins, the best experience I've had in town is Gill's Point S:
