I would say that your Acura might have some sort of barke asist? Or yor Titan is just heavier on the downward transition during inclimate conditions. I doubt tires would do any better given the situation. Maybe I am wrong as i live in Alabama. But i have driven in snow and ice and it depends on the vehicle........AND dont get me wrong the tire selection too. But i think your Acura has an assist feature that the Titan never offered.
