Two risks come to mind: 1. Pinch flats. This will be mitigated a bit by increasing your tire pressure but offroading with that much weight on a 38mm tire might just warrant exploration into tubeless territory.
2. Your rims will take more of a beating.with the narrower tire. I'd recommend extra spokes and tools for their installation in your kit. Best, D.
