This sounds a little suspect, I hope you don't mind me asking. Are the tyres winter tyres, do they have the sipes across the tread and show the snow flake symbol? Also are the tyres fitted the correct way around?
Winter tyres should enable you to drive on almost anything in winter.
Knitware - thanks for the post I dont mind your questions atall
On the way to my "Phd in tyres", I have been out to check the tyres and they all have the snow flake symbol (so they have passed the nationally agreed standard for Winter Tyres) and having researched "sipes" have checked them all (and against my neighbours tyres)and they are across the tread.
I am not sure how I check whether the tyres have been fitted the correct way round?? but they were put on my National Tyres so I blinkin hope they are
I now have two bags of building sand in the boot!!
Currently researcing which fwd I will swap the Lexus for!!
