I remember one time I rode to the pet food store and came back home with 40# of dog food on my back, and the lightweight racing bike with narrow tires remained unscathed.

I eventually found I liked slightly wider tires (like 32 or 35mm) but none of those narrow tires was ever damaged simply from me sitting on the bike.

If both your tires 'popped' when you got on then something else was wrong. And if you don't figure out what went wrong with those tires, it's likely to happen again.

It can't hurt to upgrade your tires or wheels, although the wheel mounting standards and spacings are changing so (if you have a bike that is a few years old) the longer you wait the less options you will have.
