I used Luganos for London commuting for years because they were cheap, coloured and worked, but I did get some flats and they did wear, LB moved me up to Cont Super sports plus which are much much more robust but still go well, I've worn those right through the rubber and ridden on the orange breaker layer without problems
bit hard to find in shops though but frequently on promotion online
tyre threads are rubbish anyway because everyone recomends they tyres they have on their bike
What are Winter Tyres anyway? There's enough wet around all year to use a tyre you trust in the wet, perhaps something slightly more robust but again who has a problem with robust as long as it rolls (Marathon ...), if you want to ride on ice and snow then yes, that's a winter tyre
