I usually find that those that are round, made of rubber, OD larger than the ID, yada yada seems to work well.
So much depends on where you drive, how you drive, what you look for in a tire, how much you want to spend, etc.. I usually read thru the reviews on tirerack.com after deciding if I want an AT tire, a highway all season, performance all season, high performance all season, ultra high performance all season, touring, highway summer, performance summer, high performance summer, ultr high performance summer.... (get the idea?). After I decide what category I want, then it's off to the tire comparison charts and reviews.
I used to run Michelin LTX and Bridgestone REVO's but they're pricey and I have found other tires that I like just as well for 1/2 to 2/3 the cost. Firestone Destination LT's (highway AS), Destination AT's, General Grabber UHP have all done me well.
