is there really a difference in performance with the newer model tire ? and which do you guys prefer or currently in running and how do you guys like it?
Too bad nobody has figured out how to do a blind test on tires, because I really doubt that most people could tell one comparable tire from another. And for those who could tell them apart, I'd be surprised if their feelings would correlate with any real measurements.

We have found with the Pro3 Race there is up to 27% more grip on the tires in wet weather, while decreasing the weight by 20 grams and having the same longevity and durability all while only raising the price by $2.00.nismosr said:is there really a difference in performance with the newer model tire ? and which do you guys prefer or currently in running and how do you guys like it?
Open Tubular is just a marketing name for a company's tires. The argument is something like "same construction as our tubular tire, just not sewn up and with a bead for mounting." There is no standard definition of what makes an open tubular. Any manufacturer can claim that any of their tires is an open tubular. That said, typically this designation is given to the higher-end tires in the line. Pay no attention to that designation.gitoutdaway said:Anyone have extra opinions on open tubulars?
Tires wear due to power disipation - the rubber is sheared off the tread due to either pedaling or braking forces. If you don't do a lot of heavy braking, a front tire will hardly wear at all. I have weighed front tires after 6,000 miles and seen around 5 grams of weight loss and no measureable tread thinning.cpark said:The front one looks like a lot more miles left on it while the back one might last another 1000 to 2000 miles.
It is market-speak. It *might* relate to a different construction method (tread glued to the casing rather than vulcanized?) but there is no improvement in Crr or "ride" as far as I can tell.gitoutdaway said:Thats kinda what I thought but a few bike shop people have been touting their vastly superior ride lately. IS it just a way to sell an even more expensive product?
"Open Tubular" is a term that came out of Europe, and from the makers of tubulars who finally came around to supplying high performance clinchers. Since it used to be that race tires were only tubulars, these folks wanted everyone to know that their high end clinchers were "just like their tubulars" and gave the impression that these tires were tubulars with a bead and not stitched up. Hence the "open" reference.gitoutdaway said:Figures. It is s interesting how market pressures force everyone to come out with the "latest greatest" every single year no mattter what. I'm sure this also leads to progress but so often its like re-inventing the wheel so to speak.
the 20/23/25 in 700x20/23/25 has nothing to do with width. That number denotes the height of the tire. You'll notice that across brands, there is no consistency reagrding the width of a 700x23 tire. They are all 23mm tall though. You may find that 700x25's are no wider than 700x23's once mounted (although they probably are).tarwheel2 said:Is is true that the new ProRace3 tires are narrower than ProRace2s? One of the things I like about Michelin tires is the wider tread. My 700x23 Michelins measure 25 mm, and my 25s measure 27-28 mm wide. If this is true, I will need to order 700x25 Michelins from now on. Also, do the wider treads apply to Krylions as well?
Uh, I think you are completely confused. With the exception of the thickness of the tread, an inflated tire is just about as close to round as it can be. If one tire is a 23 and another is a 25 (same brand/model) then the 25 will be pretty darn close to 2 mm wider (and taller) than the 23.wilier said:the 20/23/25 in 700x20/23/25 has nothing to do with width.
