It's okay I can take it.

The wider is better statement is just a notional idea not a hard and fast rule.

It is not as sexy to put in all the qualifiers: wider (with respect to length) matters and that it is the groups of tires that actually touch the ground matters and that location of CG matters (though often if you have an arm or other moving subsystem you don't always get control of the exact location of your CG with respect to the tires that are on the ground) and that it CoF for tires is often different for scrubbing vs. the direction of rolling and and and.
