Tyre pressure / circumference and the VC. New dog old trick?

[footstuck]

My useage
In 4wd: 5 days snow 15 days off road meets and work.
In 2wd: Tarmac the other 345 days. That’s 345 days of risking your VC
to the above problem of r/radius. I don’t need that headache.
Much easier to couple-up when you actually need it
Why wouldn't you?. . . . (cost accepted of course).

Oh sorry Freudian slip , I meant to say was keep doing
your calculations and rotations, and pressure adjustments there after.
Regularly. It must help to prevent cooking your VC,
unless you get a slow puncture without noticing it of course.
In this case refer to 'VC replacement' in the Wiki.

30,000 miles in 5 years with a new vc and it's as good now as it was when new, but 1 set of tyres, but hey 5 years is fine they should only do 6 years max anyway

light will only come on when coupled regardless of switching arrangement, telltell is operated by the pin moving to the coupled position not by the knob on the dash
