Review on Serfas Drifter Tire FPS 2 0 Inch by Kenneth Wood

My daily commuter has been using them for years. they hold up very well. my current daily 30 km round trip is a combination of concrete bike path, hammer road and city streets. I didn't know there were two versions of this tire. I usually buy them through my local bike shop and they seem to only stock the Survivor series version. The one I got through Amazon was the DRIFTER CITY CTR version, which has two layers of protection against three survivors. The tread of the new tire I got also doesn't wrap around the sides of the tire as much as the old one, and the sidewall feels a bit thinner. The city seems lighter, which could be an advantage, but at the moment I'm not sure if it will be as durable as the survivor. Just wanted to let people know that the model code for this product says CTR but the detailed product description as well as the photos included in some of the reviews are from the surviving version.
