thanks for the info
you did not do any modifications regarding the chainline?
i did some measurements today - just for fun -. my 150 / 80 Avon Azaro is 165 mm (on the 5' rim of the Paso).
there is almost 10 mm left to chainline, hence, any tire that is below 180 mm (mounted on the 5' rim of the Paso) should have no serious connection to the chain.
given this table
viewtopic.php?f=1&t=3042&start=255indeed the Metzler is the only 180 / 60 that should do it.
just as an info, i know there are more points to consider when trying to find a tire solution for the paso. still - beside the current goldentire option which the corret size - it is still nice to hear that there are at least some possibilities.
all the best, hardo
