The Ford squad was the last to finalise its enduro pairs, having signed Tander and Kevin Estre, but not formally assigned them to cars.
It was, however, long expected that Tander would be paired with Reynolds and Estre with rookie Matt Payne.
That has now been locked in, with five-time Great Race winner – and reigning Bathurst champion – to partner 2017 Great Race winner Reynolds.
The pair will head to both the Sandown 500 and the Bathurst 1000 as one of the more formidable partnerships in the field.
“I am thrilled to drive with Garth this year," said Reynolds.
"We have known each other for a long time and he’s as good as they come. He is really respected, his knowledge of the sport and his craft is fantastic, and if there is one person you want to be paired with for enduros, it’s him."
Tander said he was excited to finally partner Reynolds in a long-distance race.
“I’m excited to pair up with Dave for Sandown and Bathurst," he said. "With Dave being a former Bathurst winner himself, I’m looking forward to learning more about how Dave goes about the business of driving fast at those two events.
"Dave and I have been in the same team together in the past, but never shared the same car, so should be a bit of fun given how much of a character Dave is. But when it’s time to go to work, it will be full focus on the job at hand."
Payne and Estre are one of the more left-field partnerships in the field, with Payne set for a second enduro campaign, while Porsche star Estre will be debuting in Supercars.
“It’s really exciting to paired with Kevin," he said. "He is a bit of a global superstar with a mega amount of experience under his belt. He’s someone I am looking forward to working with and learning from as we head into the enduro rounds.
“I have done some endurance racing overseas myself last year and always saw his name at the top of the time sheets so it will be great to combine our experience and see what we can do in the back half of the year.”
Estre added: “Really pleased to share the car with Matt. He’s a talented young driver and has showed his speed many times in his career already.
“He’s a rookie in Supercars but I’m sure that he’s going to help me a lot to be on pace as soon as possible! I can’t wait to be racing with the whole team!”
