Just installed the first one on a Narrow Gauge. Clearly a more vertical profile, this tire does not touch the inside edge of the track. Centres easily in the cleat cup.
There is 3/8"s to 1/2" clearance on both sides. All the other Dunlops appear to rubbing slightly.
Rated at 70 psi, Dunlops are rated at 35 psi and is usually where I run them.
I think a less jarring softer ride in loaded conditions, they do need regular air pressure checks.
I have the new rim, waiting on an excluder retrofit.
