Bikes: Currently just an old GT Tequesta MTB, but just rebuilt from the ground up as a single speed and love it! Next project is a road fixie, looking for a donor....

MTB tire size question

I've converted an old GT MTB to a SS and am enjoying it. It has 1.5" wide rims running 1.9" tires. Can I safely run 1.5" tires on the 1.5" rims??

IF they are "marked" 26x1.5", then you could safely go to 1.25" if you want.
