The answer lies in the manner in which you drive. If you drive fast and reckless, eg. slamming pot holes, banging curbs, off roading in rocks, etc., then yes they can break, they're, after all, only byproduct of recycled aluminum cans or extruded aluminum. If you have ever seen the inside of one, you'ld see lots of little "air pockets", this meaning it's "cast" or made in a mold from molten metal. correct use will result in a lifetime of use, WITHOUT the need for "extra protection", this only adds to the cost.
Hope this give you the information you need.
