One more speedo gear question

[akirshbom]

Speedo shows 60, GPS shows 50. Was running a 17 tooth. 31" tires 4.11 gears.
Theoretically what tooth count gear do I need?

I just installed a 16, but have not checked it yet.

60/50=1.2 or 20% over speed

17 x 1.2=20.4 or 20 tooth gear

Thanks Viperwolf1 I clearly misunderstood how this works. I thought I needed a lower tooth count not higher. Good news I can go higher, can't go lower.
