Worn Out Tires

After running the tire tread depth gauge on my tires, 3 out of the 4 tires are at 3/32, while the fourth tire is at 2/32th depth. Basically, all four of my tires are bald. A quick recap of Kijiji shows no used tires. So I'm going to have to buy two now, and two later. I just hope it doesn't fucking snow before the end of November. Or I'm fucked.
