I do t think I’ve ever done tyre calibration, is this something you ‘need’ to do especially if you don’t change the gearing? I’m having new tyres fitted but I’m not really sure why I need it, I don’t have the tyre pressure monitors fitted either.
Apparently to account for rolling circumference that varies from brand to brand as well as accounting for swapping from a worn to a fresh version of the same tyre. Not sure if this means the system learns, over time, the wear of a tyre from fresh to worn, but not for a sudden change, or not? Has an effect on the DQS system making changes smoother, not sure on any other benefit with the DTC etc. but it only takes a few minutes, if that, to do given a clear bit of road.
Nothing quite like the feeling of new tyres (after they have been scrubbed in properly), especially if the previous ones were really worn and squared off.
