Digital Spedometer not displaying 81mph

Found a fun little quirk my DCLBOR AT has Was on the highway and noticed the digital speed readout would jump from 80 to 82, could not find a speed that would display 81mph. Anyone have any ideas as of why? I was thinking a possible rounding error if the speed is calculated somehow?

Also, the analog spedometer is off by 1-2mph, slightly annoying when readout says 61mph and the needle is just below the 60mph tick...but hey its a Toyota!

BTW, I LOVE THIS TRUCK!!!

T_T

 

Mine was off by 2 like tbat when i bought it, when i went up to 265 75 16 it was off by .5-1

 

It seems like they use the same ratio for every truck, even though wheel circumference varies by a couple percent.

 

81 is an unlucky number in Japanese culture. It's somewhat like buildings not having a 13th floor in many cases.

 

I believe the digital readout is based on GPS speed; which is not always correct. Though, one way to test that theory is to do 85 mph past a cop in a 35 mph zone and see what he clocks you at.

 

Seems legit.

 

Is it possible to adjust this?

 

Maybe the Hells Angels asked them nicely not to use it

 

Nice! Almost made me spit my coffee.

 

Doubt it.

I recommend slightly larger tires.

 

Mine is this way also with 264 75 16s.
