Query: Waste of money.

I had to walk my bike home twice with these. And as if that isn't hard enough with a normal tire in the heat, the "slime" tires are slower than a normal one. I could hear a "slosh" sound and it felt like I was dragging lead. I've had other tires that lasted over a year and are still going strong. Will never buy these again.
