One thing you can do is run a bigger tube. What I mean is that most 26" tubes are available in two thicknesses. Usually a 26" x 1.25-1.75 and then a 26"x1.75-2.25. If you choose the second, you'll have more rubber there.
Also tube quality isn't an issue with pinch flats or "snakebites" tire pressure and/or sidewall strength is. If you're getting a fair share of snakebites, increase your tire pressure by 5 psi, get a tire with a stiffer sidewall, or switch to Stan's or UST.
