How to Arrange Graphics (TikZ) If Using Input Command?

I am trying to arrange several figures e.g. as follows:

Those are .tikz files, and I am using input to insert them.

What I am trying right now is this:

begin{figure}[p]
        centering  
    begin{minipage}[t]{0.49linewidth}
        centering
        input{Figures/Versuche/Temperatur_Messprogramm_Messreihe_1.tikz}
        caption{Temperatur Messprogramm Messreihe 1}
        label{Temperatur_Messprogramm_Messreihe_1}
    end{minipage}
    begin{minipage}[t]{0.49linewidth}
        centering
        input{Figures/Versuche/Temperatur_Messprogramm_Messreihe_2.tikz}
        caption{Temperatur Messprogramm Messreihe 2}
        label{Temperatur_Messprogramm_Messreihe_2}
    end{minipage}
    begin{minipage}[t]{1.00linewidth}
        centering
        input{Figures/Versuche/Temperatur_Messprogramm_Messreihe_3.tikz}
        caption{Temperatur Messprogramm Messreihe 3}
        label{Temperatur_Messprogramm_Messreihe_3}
    end{minipage}
label{Temperaturmessprogramm}
end{figure}

This seems to work it would be includegraphics[width=1.0linewidth] instead of input. input however does not accept the [width=1.0linewidth] bit.

Can someone help me out?
