Kring was born in El Dorado County, California. He is Jewish. He has two brothers. He graduated from the University of Southern California School of Cinematic Arts in 1983. Discussing his beginnings, Kring said:
"I never even thought about scripts when I got out of film school. I pulled
cables and shot documentaries. I finally got a gig with commercial
house where I would come on with a camera crew as second assistant
shooting Japanese cigarette commercials. I had an oppportunity to get
into the camera crew and decided I did not really want to do that with
my life. So I sat down and wrote a script and went back to all the
people I had met, got an agent out of it and started going out on a
gazillion pitch meetings, and pitched anything I could."
Kring's first job as a screenwriter was for the television show Knight Rider. Other early projects included co-writing an episode of Misfits of Science (which, like his later project Heroes, featured super-powered humans as a main theme) and Teen Wolf Too with Jeph Loeb. Kring and Loeb would collaborate again when producing Heroes. Kring also co-wrote the 2010 book Shift: A Novel (Gates of Orpheus Trilogy) with Dale Peck.
After the cancellation of Heroes in 2010 Kring created the TV series Touch, a drama focusing on a father (Kiefer Sutherland) who discovers that his mute son can predict future events. The series premiered on January 25, 2012 on Fox and was cancelled after two seasons on May 9, 2013.
On February 22, 2014, during its Olympics coverage, NBC announced Heroes is coming back as a 13-episode event miniseries titled Heroes Reborn. It will premiere in 2015 with creator Tim Kring as the executive producer.
