Speedo gears

[Wrangled]

Anyone running 255/75R17 tires and 4:10 gears, and know what speedo gear they have?

I've seen charts that recommend anywhere from 34 to 37 teeth on the speedo gear to get an accurate reading.

Thanks for any info or experience.

That's roughly a 32" tire which with 4.10/4.11 gearing you want a 37 tooth gear. The chart in http://www.4x4xplor.com/speedo.html is GPS verified and is known to be accurate.
