I'll certainly look at a different tire next time but the original is still going strong on the back and the front is near new.
I don't think you are over inflating the tires but I
do think you misunderstanding terminology. A "blow-out" is when the tube is no longer contained in the tire and expands rapidly to the breaking point. If it is a true "blow-out" you won't even hear a hiss of air as all the air is expelled at once...and loudly.
A "pinch flat" or "snake bite" is when the tire can deflect far enough for the tube to become pinched between the rim and the tire. It is a slower event. I find it a little hard to believe that you could have a pinch flat even if you are landing straight legged off of a curb with 90 PSI in the tires. Even if you were to pancake onto a flat surface from 10 times the height of a normal curb, you'd be hard pressed to pinch flat with that kind of pressure. The tire is going to slip off the rim first and actually "blow-out".
I'm wondering if you really have as much air in the tires as you think you do. Gauges can be inaccurate, although to pinch flat a wide tire like yours, it would have to be off by 20 or 30 PSI.
Check your pressure gauge, try to land "softer" and/or get a bike that is better designed for launching off stuff.
