Get a floor pump that has built-in pressure guage, and pump your tires five pounds over pressure every night before you go to sleep.

"Over pressure" doesn't mean over the highest pressure listed on the side of the tire, but, rather, it means over the correct pressure for your body weight.

Let's assume you ride with 700 X 25mm tires.

I specified 25mm instead of 23mm because 25mm most closely corresponds to an inch, and it makes the math easier.

If you weigh 200 pounds, you need a total of 200 pounds of air pressure pushing against the pavement to hold your rims up and away from damaging objects that will pinch flat your tubes and dent your rims.

With a 25mm, or one inch tire, that means each tire should have 100 pounds of pressure pushing against that one inch of contact, so that two tires together would push with 200 pounds of pressure.

If you had a 50mm, or two inch tire, then you would use 50 pounds of pressure, so that two inches times 50 pounds would equal 100 pounds, and two times 100 pounds would equal 200 pounds, your body weight in this example.

Now, to complicate this a little, some of us, maybe most of us, ride with more weight on the rear tire than on the front tire.

For myself, I weigh 225 pounds, and I ride with 125 pounds in the rear and 100 pounds in front.

Every night before I go to sleep, I pump up my rear tire to 130 and my front to 105.

Most people ride with a 23mm tire; close enough to one inch for all the above to apply.
