smallest 22 and 24 inch tires

i need to find the smallest matchin set of 22 and 24 inch that i can.......takin an inch outta the rocker on the ram so im jus that much lower........of course on 22/24 combo.......

I called cooper tires and they have a 285 30 24 that they said they could get me in 6 weeks. i believe that bill WAS runnin them on his 300. they are around 450 a piece. not a lot of people heard about them, but cooper gave me the specs, price and measurements so i guess they are available.

Cooper is supposed to realease its new tire by X-mas. 285/30/24.
