Winterforces came off mine last Monday and the Triple Treads went on.
The Misses W409 I-Pikes are coming off today or Sunday.
40 degrees here during the day. No reason to let them waste away in the higher temps, just slow down if a small snow storm comes. If I see a forecast for a lot of snow(6"+ a couple days in a row), I'll take and hour and swap both sets back on.
