Greetings Doodle,You might find that, going forward, the original ones are fine without the second pair. I suspect it's a learning curve in action. After the winter season, try one set again; I think you'll be surprised. Gathering your senses in tune with each other goes a long way as the miles tick on. Studded tires... my only experience is on a mountain bike. That was so much fun some time ago, as the winters are now much warmer. Seeking out ice to ride on seemed counterintuitive at first. Motorcycle-wise, I've ridden my K75s in all winter conditions, even fell on ice. Oh well... youth gives one an amazing jeopardy pass. Enjoy the coming seasons, bit by bit. Remember your tires without studs become hard with little to no grip. Ride upright as much as possible with plenty of distance between front and rear.
