Assault 4×4 Wheels Review
There were a few reasons we went from 18 inch rims to 17 inch.
Firstly, we are running 17 inch in our caravan with five studs as well, so this gives us the option of switching the tires between the car and caravan in extreme circumstances. They won’t match up completely as the hub in the caravan is quite a bit larger, but it allows us the option if we were ever in an emergency.
Secondly, a smaller wheel means we have more of the tyre to work with when we let them down for beach driving or tough terrain. It gives us a larger surface area which ultimately means more traction in the softer sand and boggy terrain.
