Amos Roberts also ran in two tries in the win over Crusaders last Friday
Impressive Wigan maintained their fine start to Super League XV with a second stunning home win inside eight days.
Hull KR hit back from Wigan's two tries inside six minutes, from Amos Roberts and Martin Gleeson, to trail only 10-6 at half-time after Ben Fisher replied.
But Wigan ran in four second-half tries though Sean O'Loughlin, Pat Richards, Joel Tomkins and finally another from a flying Roberts in the dying minutes.
Richards landed four out of six with the boot to make Wigan comfy winners.
Hull KR were the last team to win at Wigan when they recorded a 20-12 victory there last May.
But Wigan, fresh from last Friday night's opening 38-6 win over Crusaders, looked invincible as they made a storming start.
Just three minutes had gone when new coach Michael Maguire's men went ahead on the say-so of a video replay after Cameron Phelps had sent winger Roberts over in the right corner.
Three minutes on, they got a second try when centre Gleeson proved the beneficiary of a questionable Phelps forward pass, improved by Richards.
Hull KR coach Justin Morgan responded with a string of substitutions, throwing on Mick Vella, Ben Fisher and Liam Watts.
And a neat offload by teenage prop Watts let in fellow sub Fisher to pull one back before the break, Michael Dobson adding the extras.
The excellent Phelps went off injured at half-time with an ankle problem, along with Rovers' former Wigan full-back Shaun Briscoe, but the home side had no shortage of playmakers.
After having another effort chalked off, loose forward O'Loughlin, again on verification of the video referee, after looking possibly offside from a Sam Tomkins high ball, skilfully gathered the slippery ball to snaffle the 50th try of his career.
Winger Richards then cashed in another neat Sam Tomkins kick, before Joel Tomkins sealed victory with try number five.
And it was left to Roberts to end the night as he had started it, going half the length of the field for a stunning finale.
Aside from the loss of Briscoe with knee ligament damage, Rovers loose forward Paul Cooke needs x-rays on his problem wrist.
Wigan Warriors coach Michael Maguire said:
"There's a long way to go but it's good to play the first two games at home and have the fans' support.
"I was very pleased with the fact we performed for 80 minutes. They are working for each other, especially in defence.
"Cameron Phelps is not looking great but we'll find out the extent from scans tomorrow."
Hull Kingston Rovers coach Justin Morgan said:
"Shaun Briscoe looks a four-to-six-week injury minimum. It's a huge blow - he's the number one full-back in England.
"In the second part of the first half we did well to battle back into the game but couldn't go on with the job.
"Unforced errors cost us second half. We were our own worst enemy. Maybe the scoreline was not reflective of how tight it was at times, but we were well and truly beaten in most areas."
