Tire size ???

I just bought a new 06' pickup . It comes standard with chromed 22'' wheels . My question is this : Is there a tire company that makes 22'' snow tires ? Thanks .

why would you even want to install 20" snow tires???
buying smaller rims and good snow tires will probably cost alot less than 20" snow tires and it'll prevent your chrome rims to get damaged in winter.

Thanks but that dosen't answer my question ... By the way my wheels are 22'' not 20'' .
