The tuner adjusts either the ractance or capatance of the antenna (or both) so as to match whatever impedance the antenna is to the impedance of the transmitter so as to maximize power transfer. NOTE that there is loss in the tuner and the greater the adjustment it needs to make the greater the loss so resonate is best for the antenna.

Note also that though an invrted V can approach 50-52 ohms... Neither a dipole or a folded dipole nor a verticle are 50 ohm Dipole 75, folded 300 verticle 32.5
