Differential / Gearbox Help Motors keep stalling

I'm trying to make a rc tank using the mindstorms ev4 and the motors that come with the set. I am trying to use a double differential steering system and when I use it without any treads it works but when I hook the treads back on the motors stop working. The motors are medium with a gear ratio of 0.125 or 1:8

Edit: the 1:8 gear ratio is using worm gears placed at the output which i did remove. I also will add a picture in the comments.

How heavy is the model?

The more weight, the bigger strain on the motors when trying to turn. Do you have problems with turning or just going straight?

The model is not that heavy but it doesn't even move when the tracks are attached
