Tires don't protect you from snake bites. It is all about the tube, and you can get heavy duty tubes that will help keep your wheel from bottoming out.
The better solution is to increase your tire pressure to 80PSI plus. This is standard practice for park, vert, and flatland riders. There is no real reason not to increase your pressure for dirt as well. The higher pressure will decrease your ability to bottom out the tire and pinch the tube against the rim.
90% of beginner riders run WAY to little pressure in their tires and run into pinch flats on a regular basis. In comparison, in the last 12 months I have not had a single flat. This is achieved by running high pressure and changing your tires whenever they start to get bald so small rocks and glass can't get through the skin of the tire and pop the tube.
