Q: What is the maximum psi for this tube?

The maximum pressure or PSI is determined by the information on the sidewall of the tire and not on the inner tube. Hope this helps.

Q: Does the same tube fit 38- 43c tire or are there seperate tube sizes in this listing? I dont see how to select the 700×38C that i need.

The same tube fits multiple wheels. I needed the 700x38C and this was a perfect fit. Just follow the instructions on the box.

Q: Will this tube fit700x38c 28 x 1 5/8 x 1 1/2 ?

Yes, my bike is 28" and the tube worked great.

Q: What is max inflation psi?

it's a pressure you should not exceed. Most tires will have this printed on the side wall. for bike tires it's normally 60 PSI, but you need to check the tire and tube.
