While we can't actully mesure it's bite force, The T-rexis actully presummed to have an incredbly powerful bite, some would say the strongest the Animal Kingdom has ever seen. Look at it's closest living realtives, Birds first and formost, some birds like the Parrot have very high bite forces for there size, and look at the crocodilain family also part of the Archosaurs group, have the strongest recorded bite force of any animal on the planet. So I'd say it's safe to say the T-rex had an extremly powerful bite, even for it's size, escilly given it would be realying on it's bite for hunting and survival, given it lack the Dromaeosauridae killing toe claw, or the longer arms of a Dromaeosauridae or Allosaurus.
