You need to inflate it to just over 100 so that the air that escapes when you pull the inflater leaves the tire at 100.
An easy trick is to press in on the tire with your shoulder as you’re inflating; really push into it, and it adds just enough to offset the air loss when you stop inflating. Dad used to use his head, and that worked great because the smaller surface area of the top of his head meant more PSI, but I’m not as tough as dad and it hurts my neck to do it that way, so I use my shoulder.
Anyway, don’t give up! You can get there, and a properly inflated tire can improve your mileage. Most people don’t keep their tires properly inflated and are just wasting money.
Use cold air so it’ll expand in the tire. Alternatively heat the tires, put them in the sun.
