Hm err... I'm afraid whoever told you that "tires is more speed efficent" was just spreading an (un)educated guess.

How so? This "tuning log" video by HectorX (that you can check when you're back or maybe now over a VPN) clearly shows that, from tires levels 0 to 10, the car gains 96 in rank fat and 52.3 km/h in fake top speed (45.6 in real top speed)... whereas upgrading drivetrain from 0 to 10 adds 96 to rank and 52.3 km/h to fake speed (45.6 real).
