I only ride for myself and don't do competitions or such. However I feel that I ride downhill twisty turns as fast or faster than others. You won't have the issue you are imagining even if you do leave the worn tire on the back.
BUT...You will put new tire on the back, won't you?
Unless you actually ride with complete abandon of your senses and safety, then you are unlikely to have this happen. Only if you have stuff like this happen to you on good tires should you expect it to happen with bad tires too. If so then your cornering technique is lacking something.
