Panaracer Race A EVO3 Tubeless Tire
The long awaited Panaracer Tubeless tire is here. After literally years of testing which includes micro-managing the minute details in pure Japanese fashion, Panaracer brings us the Race A EVO3 Tubeless tire. Personally, we have tested many tubeless road tires over the last few years and we can attest to the fact that these tires mount up square to the bead and seat-up better than any other tire we have used. Usually, we do not lean towards particular products in copy writing, but these tires are simply the best design as the time of this product review.
With tubeless tires, the majority of engineering concern is focused on the bead. The all-important bead is required to seat properly and stay in place. Sounds simple enough, but from an engineering perspective, there is a lot of thought and effort that requires specific materials and tight tolerances. This design would be focused equally on performance and safety. Back to the bead: this was the birth of Probead. Most tubeless manufacturers use a standard carbon based design. Carbon is elastic and resilient, and while it's an easy answer in the modern day, Panracer's engineers felt straight carbon wasn't the complete solution. Hence Probead, a proprietary carbon-based hybrid bead that has the distinct advantage of staying seated on the rim bead while flatting due to the carbon additives which produce a superior composition. What you get is optimized safety, with no degradation of performance.
Beyond the tubeless concerns, the tire is of pure Race A Evo 3 designation, and receives all of the Race A technology. This includes Panaracer's All Contact profile. For those unfamiliar, this refers to the actual shape of the tread that is laid on the casing. Unlike most tires, it's not round. The center of the tire features a a slight angle that descends down to the end of the tread where it meets the sidewall. The concept is simple, when the tire rolls over to a lean angle, you get complete contact or in this case All Contact. The angled tread on each side creates a point in the center of the tire for minimal rolling resistance. This angled tread design is not unique, it has been used in the performance motorcycling world for many years.
As far as durability is concerned, the Panaracer ProTight belt is what keeps these tires from flatting. ProTight is a soft woven belt which offers the ultimate protection by keeping road debris from penetrating the supple casing. And what's more remarkable than the protection, is the ProTight belt is so pliant and finely woven, it has virtually no negative effect on ride quality.
It's a fact that the ride quality is always dependent on the casing. The Race A EVO3 Tubeless features Panaracer's supple AX casing. The casing's composition features soft and flexible fibers that are strong enough for durability and handle high tire pressures, but still conform to varied and uneven surfaces. This flexibility and suppleness results in maximized grip, comfort and a certain surefooted feel in corners.

25mm mounted on Easton EA90SLX, 17mm internal width, by hand, repeat, by hand. Inflated sans compressor, no sealant, voila! No leaks, repeat, no leaks! Tubeless have come a long way from my frustrating experience w leaky tires and savagely difficult tight fitting tires from early days of road tubeless. Very pleased with these Panaracers and I was already a fan of the tubed Evo3. Lastly, tire width measured with calipers on these Eastons, pretty much 24.0mm. After a few hundred miles, measurement didnt change. All good, no clearance issues with 2014 Cannondale Evo...and yes, I dumped an oz of Stans down the valve just in case.
Pros Mount up without drama.
Cons None. Great product.

First ride on these tires yesterday - first ride ever on road tubeless - and I am impressed. Supple, grippy, fast, they ride like the best tubulars of my youth. I rolled into an Indiana speed bump (pothole) at speed. Never even felt the impact with the edge of the road crater. The Panaracer Race A EVO3s just shrugged it off and rolled through. Looking forward to many more kilometers on this new technology
Pros Sweetly supple, sticky, speedy
Cons Worried I cant set one up myself to change tires

The 23C tire measures exactly 23mm wide when inflated on a 17.5mm internal width rim, in this case Easton UST rims. They look right, they don't look "stretched" like other tires on wide rims. Panaracer clearly designed these for wider rims. Inflated with a floor pump and soapy water and so far there have been no nagging slow leaks while running dry without sealant, but that's expected with a UST rim. The rubber compound is high grip. Riding and especially turn-in and corner holding characteristics are outstanding, almost motorcycle-like if you will. Build quality inside and out is top shelf as well. Nicely done, Panaracer.
Pros Made for wide rims, build quality, handling

My first foray into the world of road tubeless, I mounted a set of these in the 25c size to a pair of HED Jet 6+ wheels. After racing the chip seal roads at the Tour of the Gila, lots of miles on dirt and gravel and even a little smooth pavement on this setup, I am a convert. No flats to-date and the tire wear has been decent running 85 psi up front and 90 in the rear. If they were a little cheaper and offered with a "D" or durable tread, I'd use them year round.
Pros Easy to mount, excellent ride quality, very aero
Cons A bit pricey for an everyday tire and a tad heavy
