I switched from winter to summer and noticed that the car was dragging to the sides on the same roads. Therefore, either Ventus Prime Three is sensitive to slope, or my winter one did not respond to road slopes. Although the sidewall of the primacy always appears black, this is obviously an aesthetic choice, but the michelin looks better, this tire is comparable to primacy 3 in terms of sensations and impressions. I'm ecstatic with the purchase.
