This bike came with Kenda Kwick Trax 700x38. I took it on a long ride today on city-segregated bike lanes is about 3cm of slushy snow and salt. The bike did really well but there were a couple of instances in heavier drifts where I felt unstable. Overall pleased but wondering if there's a tire upgrade that will improve things. I'm 90% on dry roads so not willing to sacrifice much and not interested in swapping tires in the winter.
