I'm an averagely built rider weighing ~85kg living in a middle-sized town in west Germany. Up until recently the only bike I had was a 46/16 single speed on 28mm tyres. It was used for both commute and leisure totaling ~60km a week.
Back in March I bought a Croozer trailer to carry my 3yo to kindergarten and back which amounted to extra ~35kg of total towed weight. It was hard at first but I eventually got used to the grind through the almost flat city terrain.
My assumption is that for the maximum stability on ice I need some studded (spiked) tyres. The only suitable ones I found so far are Schwalbe Ice Spiker Pro that come in 57mm and 65mm widths weighing each 1.0kg and 1.2kg respectively.
I don't care much about the extra weight but I wouldn't mind the setup being lighter either. There's also a slight chance that the wider ones aren't going to fit under the mudguards.
My questions are:
- Do I even need studded tyres at all?
- Would the 65mm tyres give me measurably better traction on ice and light snow compared to the 57mm ones?
- If so, would the extra traction be worth the increase in weight and rolling resistance?
- Are there any other brands/models that beat the Schwalbe in this category?
