D1 speedo accuracy

[loanrangie]

Went out to Warburton/Nojee on an LROCV run today after doing the camel cut to the rear guards and fitting my set of steel rims with 265/75/16 MT's, on the way up on the highway using my gps i reckon my speedo was close to spot on maybe 0.5 kph under but close enough to rely on the speedo alone.
Also was surprised how little performance i lost with an almost 3" taller tyre, really only noticed it on a long uphill section at 80kph and needing to boot it to keep momentum up .

I found mine is spot on with 255/70 16 as well as 245/75 16.

i run 31's and i thought my speedo was out by 6/7 klms
but using my gps its reading the same...?

my d2 is near on, perfect(actually reads a bit slower than actual with the standard tyres at 50% worn. this is throughout the speedo range. with a peculiar "slow" reading at around 70-90.

Thats about right then, 31/10.5/15's 245/75/16's 265/75/16's are with an inch of each other or there abouts.
