Talion Talion 6s runs good in the air, but struggles to move on the ground

I just recently replaced my rear wheel hub, and recalibrated the esc, along with new wheels. Once I was off to run it, the car struggled to move at around 15%throttle. under that it was running perfectly fine. I held the car in the air and it went full throttle no problem. once I put it on the ground and gave it throttle, you can hear the motor spinning and giving the power it needs to, but the car barely moves. Does anyone know what this could be? Any response is appreciated!

I'd say punch setting too low or loose (solder) connection

I just finished going through all of it, punch setting, recalibration, factory reset, brake strength lipo nimh mode. And still nothing

Video? What wheels did you go from, and to? Gearing? Check gear mesh. Motor wire may be loose.
