Okay, I have my new Marathon Winter tires. They were relatively easy to install on my Alex rims (stock on LHT).
I don't really need them at this point, Sunday was in the 60s and melted most everything. It's cold again, and there were some flurries this morning. I don't believe we'll get slick roads again, but I'll ride the studs a few more days just in case.
They are a little slower. They do make the "sizzling" noise on dry pavement. Other than that, they're just tires. I wish I could find some ice to try them out.
