The 26-year-old rapper presented his girlfriend with a Mercedes-Maybach ahead of her birthday next week.
Kylie posted a short video featuring the car on Snapchat and said: ''Happy early birthday to me. Yay! I love you, T.''
She added a picture of the interior and wrote: ''Almost too boss for me.''
Tyga previously admitted he had some difficulty trying to decide on a gift for his girlfriend.
He said: ''It's really just about what you feel. How do you get someone that has everything, you know?''
Tyga's present came just days after Kylie treated herself to a new luxury custom-made Land Rover.
The 'Keeping Up With the Kardashians' star splashed out on the SUV, which features flat screen TVs, two-tone leather seats and glows purple in the dark from the inside.
Taking to her Snapchat to share a video tour of her new wheels, she said: ''My new car, this is one of a kind. I got a little excited and treated myself for my birthday. How f***ing amazing is this white and maroon interior.
''The car glows purple inside in the dark.''
The motor also features black tinted windows, maroon seats and steering wheel, as well as drinks holders and trays.
She captioned the video: ''One of kind. Happy birthday to me.''
It's not the first time Kylie has shown off her cars to her fans on social media.
In November, she boasted about four of her luxury vehicles, including a Range Rover Autobiography, Mercedes-Benz Wagon and Rolls-Royce Ghost.
Her fleet also included a white Ferrari 482 Italia, worth $320,000, given to her by Tyga for her 18th birthday.
Kylie hasn't always had great luck when it comes to cars though as she and Tyga were involved in a car crash in October when his $320,000 Rolls Royce was hit from behind by another vehicle.
The incident occurred in Los Angeles after he had performed at nightspot 1OAK.
