smallest tire for a 22" wheel

hey i know this has been covered before but i cant find the topic on here. i was wondering what the smallest tire i can run with a 22" wheel is? and who makes it? thanks for the help.

Nitto and Toyo make a 235-30-R22 thats pretty damn small.

there is a 235/30-22....245/30-22....255/30-22 and a 295/25-22....but the 295 is the same heighth as the 245/30 the 255/30 is the same as 1 255/35-22....there r tie calculators on the web just google search it i use the miata one type in the size and it will tell u overall diameter and width

thanks guys for your help. who makes that 25 series tire?
