The ”natural” end for studded tires is often when the studs wear through the casing and begin to rub on the tube, causing flats.
I’ve tried to get a tire to last the season out by taping the inside with duct tape.
And the result was marginal.
While it did give maybe 2-3 times the mileage between rub-through flats, we’re talking about 40-60 miles instead of 20-something.
Between the cost of studded tires, the longevity of the studs and how seemingly easy the fix is, I’ve heard about a few others who’ve tried as well. And their experience seems to match mine.
