I would prefer more rubber between the road and wheel rim during the winter months here in West Michigan. I'm not a tire expert, & I'm struggling with wheel circumference and its affects on the speedometer and GPS systems. I'm wondering about decreasing the the Rim diameter while increasing the Tire height, to achieve the OEM tire height / circumference. Any thoughts on minimum rim ID and adjusting tire height height to acheive the correct OEM wheel circumference? Please include any thoughts on tire widths, the 8.5" seems a little wide to me.
