To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value 3.82 (round up to 4), and then divide by the tool diameter. For example, the ridiculously priced All Season 235/55R19 tires are a smidge over 29 inches in diameter, so that would mean (3.82 x 1320 SFM)/29.2 = 173 rpm.
