As long as those wheels aren't badly rusted or damaged, they should be safe to use. Just don't get careless while inflating them after a tire change, and don't mix up bits & pieces from different wheels. I like to do my inflating inside a safety cage, or at least wrap a piece of heavy chain through the hand holes and use a 10-foot-long hose with a clip-on inflator chuck and a ball valve to do the inflating. Another precaution- - - -if a tire on a sectional wheel is flat or seriously low on pressure, don't try to reinflate it without a complete teardown and inspection. Adding a few pounds is OK to keep the pressure right. Be safe!
