Once the plane started to move forward and generate lift, it would accelerate faster and faster until it generated enough lift to fly. It takes airspeed to generate lift, not tire speed. So if it takes 68 knots to generate enough lift to fly normally, it would still take 68 knots of forward airspeed, not tire speed to generate the lift required to fly regardless of how fast the tires were spinning.
