Pretty much.
I had to replace a tire on my pickup when the pickup had a flat and another tire turned out to have a bubble in the tread (and I originally thought it was just a crappy truck, silly me!) and on a Sunday the only tire place open that I would at-all trust was the Firestone/Bridgestone service center. No Costco, no Discount Tire, no Big-O, etc. In hindsight I suppose that Walmart might have been open for tires, and probably pepboys, but after pepboys broke a lug on the Cordoba and then tried to hide that they did it, I won't let them touch anything on a car ever again if I can absolutely avoid it. No three-stooges of the auto repair industry for me...
Over on
the poll, almost half of respondents have had a flat in the last 12 months, and more than 60% have had a flat in the last five years. More tellingly,
no one has said that they've never had a flat or haven't had one in 25 years, with 22 respondents as of writing this. That tells me that the ability to properly stow at least a bare-minimum of a spare tire is essential, even if the wheel and tire itself is undersized, light-duty, or even optional equipment. Someone may purchase a vehicle when they live in the heart of a major city with at least one shop open off-hours that can do tires so they wouldn't absolutely need a spare, but if they moved then that might change and if the vehicle can accommodate one, then they could correct the situation even if they have to pay dealer prices to do so.
