Hi Andy, I run lease vehicles and have never been instructed to change tyres to a winter specification. It would be an expensive exercise? Change 120 tyres (assuming not a 6 wheel tractor unit) plus the spares and then change them back in the Spring or put them all onto new rims. Depending on the severity of the snow in the areas that you visit, you could use snow chains. Bit of a nuisance having to take them off everytime you hit tarmac for a long period though. Driven correctly and with sufficient tread depth on a normal tyre, moderate conditions can be tackled without an issue to driver or vehicle. If you talk to your local constabulary road safety department, they should come out free of charge to give advice. I've had Leicestershires in for several years now around Christmas for drink driving presentations.

As Andy said, it will be down to the risk. Here in Shetland we use winter tyres year round!

Thank you all for your advice, its very much appriciated Kind Regards Andy

It is ultimately down to your risk assessment. For example, if in the past you have had damage accidents or genuine near misses etc due to skidding ice/snow, you could cost benefit it. Alternatively, you could make a judgement on the basis that due to better performnce, i.e stopping distances etc , it is a sensible thing to do based on you organisations safety culture etc. Winter tyres use a different rubber compound that is claimed to perform better when the temperatures are below 7 degrees C
