Pilot reported a NMAC while entering the traffic pattern at a non-towered airport. Pilot maneuvered past the aircraft and landed.

Narrative

I was returning to my home airport and was aware of a couple of light aircraft in the traffic pattern. As I approached on a 45 to Runway 30 one of the aircraft had made a touch and go and had turned to crosswind. Both of us were making proper position reports. From his radio calls I felt I would be ahead of him but stayed outside a normal traffic pattern to ensure good separation. I was at about 1100 feet when I spotted the other aircraft in front of me at about 1130 position and slightly above me. At the same time I received a warning from my TCAD. I maneuvered lower and to the right of the other aircraft to ensure separation; since my speed was greater than his. I passed about 100 feet below and 300 feet to the right of him and landed without incident or other conversation with the pilot; other than normal position reports.I was surprised that he was that wide on downwind and was actually in front of me. In retrospect I should have been even further away from the airport on downwind and at a higher altitude to avoid any possible conflict.
