Hello Alex, The "Profile" struct information can be found here - https://api.projectchrono.org/structchrono_1_1vehicle_1_1_ch_a_n_c_f_tire_1_1_profile.html. It describes the entire contour with a cubic spline approximating the points. See piece of code below from the source code
src/chrono_vehicle/wheeled_vehicle/tire/ReissnerTire.cpp // Create piece-wise cubic spline approximation of the tire profile. // x - radial direction // y - transversal direction ChCubicSpline splineX(m_profile_t, m_profile_x); ChCubicSpline splineY(m_profile_t, m_profile_y); To define a mesh on the tire, you need to provide the "Profile" as input. I don't see how you would not have access to it already if you defined it yourself.
