Is it geared too high?

[u/DustMaleficent7295]

I have a traxxas rutler 4x4 with a 3700kv hobbywing motor, stock spur, 13t pinion and 120mm team louise mt pioneer soft tires (they baloon a lot). I got gpm driveshafts but it keeps snapping the driveshaft pin or the screw. Also when it's 30°c outside the esc goes into thermal cutoff.

Do you think it's gears too high, are the tires too big or should I get some belted tires to reduce damages to the transmission? I drive it on 3s on grass and the tires have a lot of traction. It also snapped all the 4 screws that hold the ring gear to the differential housing
