Dry, and they can just push on, but tap LIGHTLY with a 10 or 11mm 1/4" drive socket.
 
If you put them on dry , you stand a chance of ripping the inner seal lip that rides on the valve stem.
Just a dot of oil is all you need.
 
Ive done mine and friends the same way, socket and a bit of oil on the inner seal, but u know there's a tool out there that steps them at the perfect height on the guides..dont know exactly where to get it, but it exists..didnt really think that a few mm's would make a difference on them. the seal rides on the valve, but the valve doesnt change in diameter or size at all, so why make a tool instead of just bottoming them out on the guides???..thats my .02, none of my seals or my buddies seals have ever leaked yet, ok im out!:hellyeah:
 
the tool is made so you do not cut the inside of the seal from the metal clad outside and let the rubber part of the seal go for a ride on the valve stem..
