how many miles per hour can you drive on a spare tire? Most spares recommend that you do not drive over 50 mph, and you do not drive more... how fast can you drive on a donut (spare tire)? Normally speed on a spare tire is rated to 50mph.
Thus, airbags can go off at any speed, you can even be stopped and someone can hit you and they can go off. But typically it is over 15 mph/10kps. Older cars will only deploy from a front or rear impact, but new ones will do it when ever the car thinks it is necessary. So, to specifically answer you question, it only occurs at high impacts, not necessarily related to speed.
