I am thinking of purchasing the 22 inch overfinch tiger wheels. Can someone explain to me the disadvantages of having bigger wheels?

This is going to be my first SUV so I really don't know much about the subject at all.

I am just going to be driving on city roads and highways my definition of off roading would be to cut through a median to pass trafic. How easy is it to bend these wheels? Would I even be able to go over a curb?
