It's not unusual for kevlar bead tires to be more difficult to mount than wire bead tires. It was really obvious in the early days of folding beads -- Turbos, etc. Depends on the tire and rim combination. Make sure it works and you can do it at home before you set out and have to fix a flat at the side of the road.
IMO using tire levers to mount a tire is a bad idea. Use a tire jack if you need a tool.
