1910 Fire Dept. QRT ???
I think I'd air up that tire before hitting any turns hard.
I would have guessed later than 1910, since the motorcycle has electric lights. If that were pre-'16, I'd love to see it on an HCCA 1&2 cylinder tour!
Check out the rumble seat. I bet that was a wild ride.

The photo was taken at the 1915 Astor Cup Race that was held at the huge new Sheepshead Bay Board Track just outside of NYC on October 9, 1915.
The rig is a called a Dayton Tri-Car and a lots of info, another photo and press clippings can be found by searching "Dayton Tri-Car" on TheOldMotor.com
