That does not sound safe. Can you call and reschedule, explaining that it’s not safe for you to drive?
If my tires were better I would consider making the drive, but I don’t trust them in a split-second decision-making event. I DO know how to drive in snow. It’s like riding a bike or roller skating — you never forget. But would the tires hold up if I had to brake or swerve or both? I don’t know. I wouldn’t think so, since they’re five years old. They will have to be replaced this year or I won’t even get to Walmart.
