The Panaracer Race A Evo 3 is Panaracer's all-round version of their top of the line 'Race' series. Panaracer also offers a Race D (Durable) version which comes with a thicker tread, and a Race L (Light) (read review) version which is the lightest and fastest version. Although Panaracer calls the Race A an all-round tire, it does come with a puncture belt that runs from bead to bead. Take this into consideration as most other brands call their bead to bead protected tires something along the lines of 'protection' or 'endurance'.
The Race A Evo 3 comes with Panaracer's 'Zero Slip Grip' (ZSG) compound which is a dual compound optimized for wet and dry conditions. The casing is made from an 'Ax-Alpha Cord' and a 'ProTite Shield' anti-puncture belt covers the entire tire from bead to bead. The Race A Evo 3 is available in the 23-622, 25-622, and 28-622 sizes.
As this is the first Panaracer road bike tire I've tested, the results will be very interesting for a lot of you. In the next few weeks, I'll also have reviews of the Race L (read review) and Race D coming.

Weight. My sample of the 25-622 Race A Evo 3 has a weight of 247 grams while the specified weight is 240 grams.
Size. Just like many other 25-622 rated tires, the Race A Evo 3 has a maximum width of 27 mm and a height of 24 mm when inflated to 100 psi / 6.9 bars on a 17C rim.
Tire Thickness. The total thickness of the tire at the center of the tread is 2.7 mm. The sidewalls have a thickness of 0.80 mm which clearly shows us that this tire comes with a puncture belt that runs from bead to bead. Most other high-performance tires have a sidewall thickness of 0.50 - 0.55 mm.
Rolling Resistance Test Results

|Inner Tube||Conti Race28 (100gr butyl)|
|Rolling Resistance 140 psi / 9.7 Bar||
CRR: Not Tested
|Rolling Resistance 120 psi / 8.3 Bar||
|Rolling Resistance 100 PSI / 6.9 Bar||
|Rolling Resistance 80 PSI / 5.5 Bar||
|Rolling Resistance 60 PSI / 4.1 Bar||
|Use the formula: RR (watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load|
In the rolling resistance tests, the Race A Evo 3 doesn't come close to the fastest tires in this category. When compared to the Michelin Power Competition (read review) and Continental Grand Prix 4000S II (read review), the Race A lags behind by 4 - 5 watts at the highest air pressure. At lower air pressures, the gap grows to nearly 7 watts.
Comparing the Race A to the Michelin Power Competition and Conti GP4000SII might not be entirely fair as this tire has reinforced sidewalls and a much higher puncture resistance score (see below). When we compare the Race A to the Michelin Pro 4 Endurance though (which scores similar in the puncture tests), it's still lagging behind in the rolling resistance tests by 2 - 3 watts.
Puncture Resistance Test Results
|Puncture Resistance Test Results (higher is better)|
|Puncture Resistance Tread||16|
|Puncture Resistance Sidewall||9|
In the tread puncture test, the Race A scores a very impressive 16 points which is higher than any other 'all-round' tire and even comes close to the Conti Gatorskin (18 points) (read review). The 'ProTite Shield' used by Panaracer seems to be doing a great job at protecting against punctures.
In the sidewall puncture test, the Race A sets the highest scores of any other road bike tire tested to date. This once again shows the Panaracer 'ProTite Shield' to be one of the strongest puncture belts available.
Although Panaracer calls the Race A an all-round tire, it scores much higher in the puncture tests when compared to traditional 'all-round' tires likes the Conti GP4000S II (read review). Rolling resistance on the other hand, is higher than the competition even when compared to tires that nearly score the same in the puncture tests.
I have a feeling the Panaracer Race A (all-round) should actually have been marketed as a 'protection' or 'endurance' tire as it's a much stronger tire than many other all-round tires. I'm looking forward to testing the Race D (durable) to see how it compares to the already strong Race A. Rated 4/5 because puncture resistance is that good.
