OK, thanks. They must have only looked up the "effective date" of the overall set of tire and wheel specs regulations that contained the tire marking rules, without bothering to actually read all the tire marking rules to see when they were actually required to start. Also must not have read the rule about stickers and tags being allowed until 8/1/68, or the preamble to the final Regs that discussed the mfrs' various requests for delays, and the accommodations that DOT put in place as a result, extending the deadline to comply with the marking rules well past 1/1/68.
