Mine has 13 inch tires and I have never had a problem with clearance.

Cobra say that the ground clearance is 16cm (if trailer is level or nose down obviously). If you were towing along ruts then if the axle is clear than the drawer should be clear. If you are driving over crosswise big humps or deep ruts then there could be a problem. I would like there to be a quick tool-free way of removing the drawer in such situations but as far as I can see it would need removing one of the latches.

The drawer takes a lot more stuff than I anticipated.
