These are my favorite tires. I use them on a city – commuter – club bike. I do about 12 to 25 miles just riding for exercise, and then 40 mile group rides. I would not buy the tire with the wire in them, as they are heaver. These tires roll or pavement with little resistance, just the middle hits the road until you hit a hole or bolt then then pancake out and take the bump. Very nice smooth ride. They have kevlar so you tend to get less punctures. nice looking tire with a great tread design. When you are putting them on make sure you get the tread design going in the right direction. arrows point forward. This is my favorite tire. I will try the 25mm next time and see if that does as well, if so cutting a bit of weight is always good. I would not buy 32mm, unless you are going to use them in the park or in the woods or something. The tires are just too heavy. However with 28mm I am able to cruise about 16 mph for an hour or so on a cromoly – steel bike – that is a decent speed for just riding. That is all I know about that.
