But since you are already inflated to the max pressure, this won't help (and you are in danger of blowing the tire off the rim).
My advice is to learn how to ride to avoid these pinch flat situations, it isn't that hard but you do have to pay attention. Failing that, you could switch to tubeless tires which are more forgiving in this situation.
You're probably right, however, with the uneven pavement and frankly my desire to ride standing it'll be hard for me to change even though I know it puts more than the average amount of pressure on the front tire. Like I said, I avoid direct impacts to both tires by hopping but i'm sure the incessant landing from sidewalks on the tires at high pressure doesn't help. I just didn't think I rode that differently to have this issue so often.
I'll check out the tubeless, too.
