What is going on here? (Bug or just weight?)

https://reddit.com/link/1u7dmj8/video/ekfpiphaan7h1/player

Truck gets pressed to the road surface and seems to clip with it (wheels are partially below asphalt). I thought that weight could be the reason for it and in the end of the video, it seems like it but when I drove up the road, near farmers market, the truck began to clip with the road again despite the weight being significantly lower than before. Is this a bug or was my load still too heavy? Trailer is vanilla, Truck is from the Mercedes-Benz DLC and only mod involved here was Auto-load.
