So after using these "spider tires" I've come to the conclusion they are junk for urban driving. The smallest rock, thumb tack, etc.. goes right through the tire wall. The rubber is so soft after driving 10 minutes my thumb nail could dig a hole in it. So I'm in the process of taking these off and leaving them for winter or I might sell them to someone who likes these tires.
I've ordered a replacement tires that are higher quality. Lets see how that works out.
