The work analyzes various ring-theoretic properties of the endomorphism rings $\tilde\Lambda^{op}$ of strong tilting modules in the category of left modules of some truncated path algebra $\Lambda=KQ/\langle\text{all paths of length }L\rangle$. The indecomposable summands $T_i$ of the strong tilting module $T$ are described combinatorially and graphically. The endomorphism ring $\tilde\Lambda^{op}$ is analyzed by means of the homomorphisms between the $T_i$. A bound for both the Loewy length of $\tilde\Lambda$ and for the right finitistic dimension of $\tilde\Lambda$ are obtained in terms of the quiver $Q$ and the number $L$.
