The Black Country side have conceded just seven goals in their 12 League One matches so far.
Ikeme believes that fielding a regular back four of Matt Doherty, Danny Batth, Sam Ricketts and Scott Golbourne has made a big difference for Wolves, who have been relegated twice in the past two seasons.
"Everything seems a lot more stable here now," Ikeme told BBC WM.
"It's nice to go into games knowing what the players in front of you are going to do. It gives me less to do. Some of the last-ditch tackles the lads have been putting in have been brilliant."
