Unbeatable price. I have to admit that they seem very cheap. I used them to store my winter wheels with tires, not just tires. The weight is about 60 kg each. The bag has never been torn or torn. I even had to lug a stack of 5 wheels on the bottom wheel by the bag handle and it didn't break. They were thrown in and out of Uhaul. And still no visible damage. I'm sure such violence will destroy them. But they held up well for 6 months.
