Crime Fighters and Calibers also make decent grass tires.
For gearing in the grass, I would start out around 44/16 or 44/17 with that motor. Grass is hard to predict. Taller grass will require a smaller pinion to control heat. For dirt use, an 18 or 19 pinion would be perfectly normal. I would start low and monitor the temps. If you find the motor and ESC temps to be right around 100F, you can go to a taller pinion.
On a side note. You may need some capacitors on your receiver if you are using the MMP's BEC with that servo.
I found the MMP was fine with that Servo but not the 1015 which the SC8 has (MMM Speedy) but I have put a Spektrum Cap in anyway.
Grass track is usually very short and well maintained which is why I queried using the AKA tyres. Badlands I was told trimming the outside lugs and dropping ride height would help with traction rolling?
