OK, so today had the PS4S tyres fitted. Did not drive 10kms and had the S4 dash going bananas about the loss of tyre pressures. Even tried the IT first rule - turn it off, wait 20seconds, then re-start. No difference. Only from reading this forum did I restrain myself from throwing the MMI out the window. Not knowing the pressures set by the shop, I drove to the petrol station & dropped the pressures from 41:39 to 39:39 logged into the MMI.
Soon as I got home, ever suspicious SWMBO said “it’s lower!!!!! (giving me the look), the tyres are closer to the wheel arches!!!!!”. the old tyres were P Zeros. I think I said something dumb like “no it’s not, same tyre pressures”. Might as well have talked through my @$$. Absolutely no doubt the matter will be re-visited the next time we are in it together, with, at minimum, identical attitude.
So, how do I explain that one, without anything in her hand becoming a missile?
