Sprocket, Wheel, Tyre sizes and ratios

[Stevie Wonder]

I recently picked up 19” YZ rim that’d been laced to a DT hub, it also came with a set of AC10’s that where brand new and I paid less then the pair of tires alone. Anyway since doing this I’d had some trouble trying to find wheel sizes and the sprocket sizes they run and stumbled across this and thought it could be useful to someone in the future
I’m pretty sure it has the majority of mx, trail bikes and off-road bikes of all years and manufactures.

Also any info on what the DT’s gearing will be like with a 19” rear and 13-51t sprockets
