Very stiff and hard rubbery and I fell like oval or a bumps shape, you fell it more when driving slow

I depended on the name, Pirelli. This tire is very noisy on the highway. My RAM has on-board tire pressure display and has been steady over the years. These tires do NOT maintain a constant pressure during summer and they will lose 7-8 pounds of pressure on very cold days. Normally 38-39 psi drops to 30 psi in single digits. I can't recommend these tires.
