Confusingly, that wikipedia page cites the same IBTrACS system that I referred to, and in that page[0] the max intensity is listed at 213 knots. The data shows that the 213 knot speed was seen for measurements across twelve hours on 1958-09-24.

You are looking at the data for the CMA (China Meteorological Agency). The official data center for the Western Pacific according to the World Meteorological Agency is the Japan Meteorological Agency (JMA/Tokyo), but the IBTrACS dataset does not have wind speeds from them for 1958.

The Wikipedia article is sourcing data from the JTWC (Joint Typhoon Warning Center), the US wind column for 1-minute sustained wind speeds. In general, the Wikipedia convention is to include wind speed data from the JMA and JTWC when available.
