Speedometer adjustment
I'm running smaller tires and it's thrown the speedometer off by 10MPH.

Does anyone know how to adjust this???

There is an option within the Instrument cluster settings page to change the tyre size fitted.


Click image to enlarge

You will need a diagnostic tool to do this though.

@T1G UP,

a nanocom or MSV will allow you to do this, though the stored tyre sizes are minimal and relate to LR stock sizes and not after market larger tyres.


@Sockpuppet,

if you do it yourself then you know for a fact it was done correctly. Whistle Thumbs Up

I'm running 245/75 on Wolf wheels (16"). They are Cooper M&S for light truck.

Sorry if it posted 3 times.....I might have a twitchy finger from too much coffee.

I don't have access to a dealer nearby so I may be screwed.

With that tyre size you will only be 2.4 mph under from a stock tyre of 235/85/16 NEVER TAKE LIFE SERIOUSLY. NOBODY GETS OUT ALIVE ANYWAY

I agree with everything said but it is "off" almost twice that amount.

Before I installed the tire I noticed it was fairly smaller than what I "calculated" based on the stated size. Apparently there are differences from manufacturer to manufacturer.

This is on a Puma.
