Hello @Lorenzo Candelpergher
I have just changed my tyres and wheels, and I do know for a fact that new tyres cause some trouble offroading in the first couple of weeks until they sit tightly on the wheel bead
Nevertheless, my new wheels are Method with bead grip technology that should be preventing pop-outs better than normal wheels, yet of course not as good as bead locks
I will leave this to your judgment. If you believe its not recommended to be on an intermediate trip when trying new tyres, then I will gladly withdraw
