My tires are pretty old, dry rotted, and aren't as round as they used to be. I'm looking for new tires with wider spaced lugs to improve snow traction. The current tire size is listed as 4.10/3.5 to 6 but Im not exactly sure what that means. When im searching for new tires, I see some listed as 4.10 to 6 and I'm wondering if that would be a good replacement. Do you think that size would work? Also any recommendations on what kind of tires to get and where I might find them?
