(b) any rear wheels originally certified as meeting SFI Spec 15.3 must bear a wheel conformance label indicating compliance with SFI Specification 15.3 properly affixed to each wheel per the specification (including re-certification if applicable); and

(c) any rear wheels originally certified as meeting SFI Spec 15.4 must bear a wheel conformance label indicating compliance with SFI Specification 15.4 properly affixed to each wheel per the specification (including re-certification if applicable).

If your wheels had SFI stickers on them when NEW they better have them on come January 1st.

Don't want anyone getting bounced because they thought the rule didn't apply to them.
