The wheel/tires of the ROC-DS are significantly larger than on the ROC. Do they give any measurable benefits to traction, speed, and stability?

All ground vehicles had changes in Alpha 3.13.0 to help improve their handling, but the ROC-DS also benefits from increased traction and stability over the base version thanks to its wider stance. However, the ROC-DS is currently 8m/s slower than the ROC due to the extra mass.
