Typical stainless lockwire is 304 alloy rated at 75,000 psi tensile strength.
0.041" is good for the wheel spinners.
0.041^2X3.1415927X75,000=396.07 lbs

0.032" is strong enough though.
0.032^2X3.1415927X75,000=241.27 lbs

Both more than enough to prevent a light weight spinner from rotating during heavy braking.

Please don't use the excuse "I like to leave my safety wire loose so I can see that the spinner has moved and destroyed my wheel by the time I noticed it".
Its along the same lines as "I like to leave the chain binders loose on my Frontend Loader so I can see when it shifts off the trailer".

Loose safeties in Aviation are simply put: An embarrassment and and subject to immediate replacement. Same goes for Neutral and Negative safeties.
