M+S won’t cut it. It needs to have the symbol below on it or be studded.

As for the weight, more weight does not necessarily equate more better. There is a sweet spot where going on either side of it makes it worse. Too light and it gets no traction. Too heavy and it just sinks into the snow and digs itself deeper instead of moving forward, especially if the tires are too skinny for the weight which is likely the case for Cybertrucks judging from all the videos of them getting stuck in sand. I presume that where this sweet spot is depends entirely on the conditions.

Also the RWD pickup trucks are especially bad in the snow not solely because of the lack of weight over the rear driving wheels, but mainly because it has to push along the undriven front wheels that are carrying most of the truck’s weight. It isn’t as much of a vehicle weight problem as it is a weight distribution over the driving wheels problem.
