I need advice for micheline tires pro race2

Hi girls!

I need advice.

I have a trek 1000. My bike came with bontrager select tires 700 x 25c and Alex alloy rims.
I tried to put micheline pro race2 700 x 23c tires, but it didn't work.
They look small on the rim.

I'm using same tubes. The tube says from 18 to 25 tires.
Also the tire tag recommend 87 psi.

Do I need to buy 23c tubes? Or these tires do not fit the rims? Or psi is wrong?

Please help.

(Feel free to correct my english).

87 PSI is the minimum. 116 is the max.

I use 23s also and use 100-105 psi.

What do you mean? You did not get them mounted on the rim; or they just look small on the rim? They are smaller tires so they will look smaller on the bike?
