I have them on mine and there is no highway noise. My VX is on the highway 80% of the time when its out and I have yet to even give them any thought because of noise.

As for traction, they hold very well on dry and wet pavement. I have yet to have them in the snow since I only got them around Dec and it never came out of the garage in snow because the Rex was too much fun in it with its summer shoes on, heh.
