I WAS STUNNED BY HOW MUCH COLD TEMPS AND MASSIVE TIRES LIMIT EV RANGE ON A SNOWY WINTER ROAD TRIP!

EV Channels Review

This video details the impact of fitting larger 37-inch BFG Mud Terrain KM3 tires on the GMC Hummer EV's efficiency during a snowy winter road trip. The reviewer notes the aesthetic improvement and off-road capability offered by the larger tires, but highlights a significant decrease in miles per kilowatt-hour, dropping from an expected 1.5-1.6 to as low as 1.1 and ultimately settling at 1.3 miles/kWh by the trip's end. Cold weather and uphill driving at highway speeds exacerbated this reduction. While the Hummer EV's robust build and all-wheel-drive system handled the challenging conditions well, the reviewer points out the trade-off between off-road prowess and on-road efficiency. The video also touches on the Hummer EV's charging speed, the inconvenience of charging infrastructure for large battery EVs on long trips, and the ongoing debate about the future of driving versus autonomy. Despite the efficiency penalty, the reviewer concludes that the 37-inch tires look 'right' on the truck and are a worthwhile upgrade for those prioritizing aesthetics and off-road capability, though it comes at a considerable cost.
