What are the smallest size tires for 20's?

I have a 225/30/20 on the CL, IF I ever need new tires I will probably give the 215/30/20 a shot.

Well I ordered 225/30/20's last night, thanks for all the info and opinions!

I'm running the 215/30zr20's on x8.5's and I was scared about driving on them, but with running 48-50psi, (Which is high, but recommended to run higher pressure the lower the profile) in them and not driving locked up and going around big bumps like you should be with any small profile they actually ride great. Of course mine isn't a daily, and doesn't make state to state trips but have driven around on them before cutting out all the suspension for a re-build. There is a difference in size between the 225/30 and 215/30, it all depends on what width wheel you are running the more it stretches the shorter the tire will be. And all tire manuf. tires might say they are the same size but the overall diameter will be off slightly from brand to brand.
