The article contains experimental evaluation of technological possibilities of the wave-shaped profiles and confirmation of classical metal flow on profiles of wheel rims with toroidal flanges. The following parameters are recorded during the experiments: temperature in the finishing gauge, rolling force in the 2$^{nd}$, 4$^{th}$, 6$^{th}$ and 7$^{th}$ passes, current, voltages and motor speeds. The analysis of experimental data of rolling profiles 7.0-20-03, 8.5-20-03 and 228G-020-01 shows that technological capabilities of special rolled products for the truck wheel rims with wavy central part are much higher than serial profiles, where the central zone is of rectangular shape. It is possible to reduce the mass of profiles without changing the process parameters, $i.e.$, rolling force and torque. This indicates the influence of additional and kinematic effects on the deformation zone in real production conditions.
Key words: wheel rims, metal intensity, energy and power parameters, rolling, workpiece.
