Is it dangerous to buy used tires or is it just being overly cautious?
I've got an old car, and I'm thinking about getting used tires for winter. But if they're actually dangerous, maybe I should find new ones instead?

I bought used tires once, and here's what I figured out: the thing that matters isn't how old the tire is in years, but how many miles are actually on it and how it was used. Tread wears unevenly - one tire can be half worn out in a couple years of aggressive driving, while another one's still going strong after five years of careful use. So you need to look at them yourself, don't just take the seller's word for it. Check the tread depth with at least a ruler, look at the sidewalls - see if there are any cracks, bulges, or scuffs. If a tire was underinflated for a long time or sat in the sun, the rubber loses its elasticity, and you can see that.
Here's the honest story: I grabbed a pair of tires from a salvage yard, they looked fine, but already in the first season they started whining at speed and didn't grip well on wet asphalt. Turned out there was a hairline crack inside that I missed during inspection. After that I didn't mess around - bought new budget ones and stopped worrying. On an older car you can find a budget option, but then the tires really need to be in good shape, not just "no obvious holes."
If you're unsure or don't have time to hunt around, then yeah, easier to just buy new - they'll last longer and you'll drive with peace of mind. But if you're willing to put in the effort and pick carefully, there's nothing wrong with used tires, just don't be lazy about checking them before you buy.
It all depends on the condition - if the tread is fine, there are no cracks, and they weren't stored in the sun, used tires are safe. The main thing when buying is to check the manufacturing date (no older than 5 - 7 years), inspect the sidewalls, and ask them to measure the tread depth, especially for winter tires where that's critical.
The main danger with used tires isn't the fact that they're old, but that you don't know their real history. Sure, if you're lucky enough to find tires that have only been driven around the city for two seasons and stored in a dry garage, that's a perfectly normal option. But in practice, sellers often hide the real condition: there can be micro-cracks on the sidewalls, balancing issues, hidden bulges under the tread. This is especially true for cheap listings.
The biggest thing people often miss: imported used tires often come from warehouses where they've been sitting in poor conditions for a long time. Rubber dries out over time, loses elasticity, and even if the tread looks decent on the outside, there can be delamination inside. This is especially critical in winter - when it's cold, stiff rubber doesn't grip as well, drains water worse, and the risk of aquaplaning goes up.
If your car's already getting on, like you said, and you've got the extra money, it's better to buy new budget winter tires. First, budget doesn't mean dangerous - there are plenty of reliable lines at reasonable prices. Second, you'll know what you're getting, you won't risk hidden defects, and they'll have plenty of durability left for several seasons. On a car that already needs attention, you don't need to add variables with unpredictable rubber.
My friend drove on used tires in winter, and she ended up in a situation: the tires looked fine, the tread seemed adequate, but after the first icy patch one started slipping before the others - turned out there was a hairline crack inside that's hard to spot during an inspection. So the risk is real, simply because you don't know how the tire was used or whether it was ever in an accident.
If your car is old and your budget is tight, you can go with used, but only if you do a thorough inspection - look not just at the tread but also at the condition of the sidewalls, check the manufacturing date. It's better to buy from an honest seller who'll tell you the history. Or look for cheap new winter tires - sometimes the price difference isn't that big, and peace of mind is worth it.
