Before I had this truly crap cheap Wanda king tires. But the walls are so thin it actually had much lower rolling resistance than my current Gravelking plus tires!! I can cruise a couple mph faster on it but flats so frequently I had to let it go. The walls felt like paper, crazy thin, while the gravelking plus felt like thick leader hide.
