Speed symbol chart

Every speed symbol in speed order and again alphabetically, with the ZR and bracketed-symbol notes printed alongside rather than in a footnote.

About 1 page printed. Every figure on this sheet is free to read on the speed symbol chart, with its sources.

These are independent publishers, not independent measurements. Each one reproduces a table originally set by a standards body, so agreement between them shows a value was transcribed correctly, not that the underlying table is right. Where a figure is safety relevant, check it against the tire manufacturer's own data before relying on it.
