Dec 20, 2003 8:08 AM | | what type, size, make and model is the tire in question? 42 could possibly be its width in millimeters if it's a pretty narrow mtb tire, or a pretty fat 700C cross tire. no clue what the A stands for. |

It is the hardness of the rubber compound. Lower the number, softer the tread. 40 & 42 is usually a downhill tire. XC tires are usually in the 60-70 range.
