Tire question?

I often see experts on here saying that if you have one flat you should change all four because of the "overloading" that occurs on the other three.
I am putting on new brakes, how do I jack it up so that additional stress won't be transferred to the "off" tires?

What makes you think they are experts? If your tires are old, look at the DOT code, like 8 years; I would consider replacing them all.
Going down the road, with humps and bumps and turns, you will transfer more load to tires then jacking ever will.
