i say, unless snow is forecast earlier, put them on mid december then if the weather is awful over xmas when some places are closed down you are not left not being able to see family etc due to poor summer tyres.
am leavin mine till about 15th dec, as i say fitted them last year 1st dec and was too early, but want them on before xmas
early Dec by the looks of the weather
It is decided - mine will go on on Saturday. The weather forecast sounds pretty gloomy from the middle of next week
