The Vittoria Diamante Pro Tire is constructed from Kevlar Carbon 3D to give you good traction on the road while maintaining a low rolling resistance. The twin tread system from Vittoria uses a harder tread on the center where most wea...
I have owned quite a few tires in my few years of riding, and these are among my favorites. The only one I have experience with is the 25c version. I switch wheels and tires often, but i have had this tire since the spring and I have done at least two races on it. No flats to speak of, and I train a lot on chip seal roads. I also don't run much pressure in it either (about 105 when on the rear, 90-95 in front) and I am around 190lbs. I suppose everyone has different luck with tires, but racing tires aren't meant to ride or wear like Gatorskin Hardshell.
Strengths: Color...seriously, thats it. Oh, and that they are "from Italy" although likely the rubber is from Thailand, just like Vittoria tubes....so...color only, maybe brand name.
Weaknesses: Where to start: Price (in relation to the REAL weakness...) durability, rolling resistance, tread pattern, sidewall quality, center ream thickness, handling...
Wow. I have been racing since 1985, not just riding...racing. Raced pro for several years throughout the mid to late 90's and still race as hard as ever, and NEVER EVER have I had the kind of flats I have had with the vittoria Diamante's. Absolutely mind-boggling.
Of EVERY ride I ahev ahd on these in the alst month, I have ahd at least one flat. EVERY RIDE!!! Last night (10/4/12) I had three! THREE!!! In less than 23 miles.
I am an ULTRA loyal Vittoria fan. Tires, tubes, tire liners, valve stems, valve extenders on all bikes, heck, even my levers are from vittoria. but never, have I EVER felt so totaly screwed by Vittoria. I will likely just send these back to my local rep and expect nothing in return, just to voice my absolute disgust with these tires. I am absolutely flabbergasted that I ran almost an entire season with a set of Zaffirro pro's on my trainign wheels, passed them onto my wifes bike for her to use, and she has yet to ahve ONE single flat. But the higher quality, higher TPI count and MUCH higher priced Diamante's have had a flat EVERY single ride.
Please...for the love of our sport, and for my hope and blessings to be on anyone reading this as a fellow rider, PLEASE do not waste your money on these tires. This is my second pair, with the same results. Less than three weeks old, and a flat on every single ride. No exageration, no kidding, no joke.
Amazingly worthless and ridiculous tires that have cost me time, money and countless wasted rides this year thus far.

Strengths: Vittoria Diamante Pro II - great grip, excellent weight, very puncture resistant, super speed
I use these form over 4 years and they are great! I train and race on them without any mercy and they suffer a lot but still I can count on them. Last pair lasted 12k km. They wear but if you want to have a grip you have to accept the wear. There is no other solution. I don't believe in stories of super resistant, super grip, super cheap, super long lasting tires. Any plastic Kendas will last longer but the biker himself possibly will not survive. In the race or hard training you have to trust your tires... and Diamante Pro are worth of trust.

Strengths: Fast Rolling
Came on the bike and have only lasted 3 months (2000) and all the tread is gone on the back, down to the casing. Never gave much confidence in cornering, felt squirmy and didn't like to be lent over (tall narrow profile?)
