Snow studs will be on shortly and they are like armoured - my risk is frosty mornings on canal cobbles with water overflow. I'll fit these and I should be thorn free. Although looking chilly tonight ! I've gone all year on these tyres off road (just bridleways etc for this particular bike) and not had an issue, but the canal banks have had the hawthorns cut.... Not too fussed as I'm only commuting two days a week and can check the tyres next day. Got a big supply of patches and glue, and it doesn't take long to sort.
