This is the answer I got today.
We have had customers who have fitted the hugger to bikes with both size tyres. It seems to depend on the profile of the tyre.
We advised our last customer with a 55 tyre to fit it (maybe with some spacers) and to see how it sits in regards to the tyre, and if it’s sitting too close, to send it back. He has been back in touch; to let us know it fit fine.
We only leave the suggested tyre size on, so we can tell customers individually of the reasons. J
