Tyler, the Creator -- I Was Driving Justin Bieber's Ferrari

Tyler, the Creator says Keyshawn Johnson is DEAD WRONG -- claiming HE was driving Justin Bieber's Ferrari during the infamous chase through Calabasas.

Tyler tweeted the admission this weekend ... writing, "That Was Me Behind The Wheel Of Justins Vehicle."

He added, "Don't Blame Him. People Are Actually Evil Swearing Up And Down That It Was Who It Wasnt."

Bieber tweeted a response -- "All good buddy. i deal with this everyday. thanks though. the baby aint mine either."

Tyler's message was clearly intended for Johnson -- who told TMZ he personally witnessed Justin in the driver's seat after the car dangerously sped through their gated community. We're told at least 3 other people also saw Justin behind the wheel.

Either way, the residents of Justin's neighborhood are PISSED -- and are threatening to withhold their HOA dues until the community takes action against Bieber.
