If anything that tire will probably afford the rim more protection from the road and curbs. My silvertip has probably the same double walled kinetix comp rims as your uno and they are holding up just fine.
As for rolling resistance I have found it is a component of both pressure and tire compound. My Dahon came with 20x1.35 scwalbe kojak tires and it felt fast until I built my bully with hookworm tires, bikes with near identical geometry and identical drivetrains at the time. To maintain a similar speed on the same terain would require significantly more effort, when I switched that bike hookworms the performance improved imediately, I verified speeds with identical cateye strada cycling computers. In between I had tried animal ASM-R folding 110psi 1.95 tires which were soft compound and they sucked worse than the kojaks, the hookworm tires are thick enough with a hard enough compound to have minimal deformation at opperating pressure, I run mine at 80-95psi.
I would try the hookworms they are a cheap experiment
