Hi Adam, In a similar vain to Geoff, we don't have sustained winter weather in this country to justify a second set. I do a lot of travel to Sweden and Finland and it's a whole different story. Hire cars are fitted as standard with winter & studded tyres October through to March. Many of the guys I work with have two sets of wheels for their car, winter tyres on a set of steel rims, these are bolted to the garage wall March onwards. The steel rims help stop damage to precious alloys in any sliding action and minimise the corrosion when grit is laid on the road. Like Geoff, I've managed without them since 86 having only one moment where a rapid snowfall (in April) caught me (and the road authorities) unawares and with just under 2mm of tread - grip was an issue. Best regards, Dave
