If a wheel gets significantly buckled (i.e., bent by sideways force so that it's out of true by a couple of centimetres) is it safe to use if it can be brought back to (acceptably) true? Or is it new bike time?
You can dismantle it, bend the rim back to a manageable shape and then build it back, but there's the chance the rim may crack with all bending and unbending. Not worth the hassle, if it cannot be saved by tensioning spokes its better to replace
