Tire Test - Vittoria Rubino Pro Speed

The Vittoria Rubino Pro Speed G+ is the fastest and lightest member of the newly introduced Rubino G+ tires. With a specified weight of just 180 and 190 grams for the 23 and 25 mm versions, this is one of the lightest tires on the market. Even the much more expensive Corsa and Corsa Speed have a higher weight. According to Vittoria, the Rubino Pro Speed should also provide a lower rolling resistance than the new Corsa G+.

To achieve this low weight and low rolling resistance, the Rubino Pro Speed comes with an 180 TPI nylon carcass without any additional puncture protection. A thin layer of triple compound rubber provides a high suppleness and low rolling resistance at the cost of shorter tire life.

When I first heard about the Rubino Pro Speed it seemed like a strange tire. The Rubino tires are mostly known as mid-range tires that provide decent rolling resistance and puncture protection. Most people that are willing to sacrifice puncture resistance and tire life for a lower rolling resistance seem to buy the most expensive, no compromise tires. This seems like a no compromise tire as well, but is it fast enough to justify decreased puncture resistance and tire life?

Size and Weight Measurements

Size and Weight Measurements (Bike Wheel: 622x17C, Pressure: 100 psi / 6.9 bar)
Measured Weight 206 grams
Measured Width 27 mm
Measured Height 24 mm
Total Tire Thickness Center 2.3 mm
Total Tire Thickness Sidewall 0.5 mm

With a measured weight of 206 grams, the 25-622 Rubino Pro Speed weighs 16 grams more than specified. Measured maximum width of the tire comes in at 27 mm, height is 24 mm. This tire is a bit bigger than specified, most other tires seem to come in close to 26-27 mm.

The total thickness of the tire at the center of the tread is only 2.3 mm which is much thinner than most other all-round tires. When we compare this to the Rubino Pro G+ (read review), the Pro Speed is 0.7 mm thinner. Because the Speed doesn't have an anti-puncture layer, my estimate is that there is 0.3-0.5 mm less rubber to wear down. The sidewalls are a bit thinner as well at 0.5 mm Vs 0.55 mm for the Rubino Pro.

Rolling Resistance Test Results

Rolling Resistance Test Results (Speed: 29 kmh / 18 mph, Load: 42.5 kg)
Rolling Resistance 120 psi / 8.3 Bar 11.9 Watts
Rolling Resistance 100 PSI / 6.9 Bar 12.6 Watts
Rolling Resistance 80 PSI / 5.5 Bar 14.3 Watts
Rolling Resistance 60 PSI / 4.1 Bar 17.4 Watts
Rolling Resistance Coefficient (Crr) 120 psi / 8.3 Bar 0.00357
Rolling Resistance Coefficient (Crr) 100 psi / 6.9 Bar 0.00378
Rolling Resistance Coefficient (Crr) 80 psi / 5.5 Bar 0.00429
Rolling Resistance Coefficient (Crr) 60 psi / 4.1 Bar 0.00522

Rolling resistance is very low at high air pressures. With a rolling resistance of just 11.9 watts at 120 psi, the Rubino Pro Speed outperforms popular tires like the Conti GP4000S II (read review), Schwalbe One (read review), and Vittoria Corsa G+ (read review). This strong performance shows us what can be accomplished by using a thinner carcass, no anti-puncture layer, and a thinner layer of rubber. I'm not sure if Vittoria uses a different kind of 3C compound mixture on the Speed G+ Vs the regular Rubino Pro G+.

At lower air pressures, the performance of the Rubino Pro Speed isn't as impressive as at the higher end of the pressure range. At air pressures lower than 80-90 psi, the performance of the Speed falls apart and it gets overtaken by the previously mentioned competitors. When using this tire, it's important to keep the pressure up. Maximum air pressure is 130 psi, which is slightly higher than most other 25 mm tires.

Puncture Resistance Test Results

Puncture Resistance Test Results (higher is better)
Puncture Resistance Tread 8
Puncture Resistance Sidewall 3

What can you expect from a tire with a thin carcass, no anti-puncture layer, and not a whole lot of rubber when testing puncture resistance? Not much, unfortunately. With a tread puncture score of just 8 points, it scores much lower than the premium tires that offer close to the same low rolling resistance. Those tires do use an anti-puncture layer and a thicker layer of rubber and seem to score in the 11-12 points range.

On top of a low tread puncture resistance comes a low sidewall puncture resistance. With a score of just 3 points in the sidewall test, it sets the lowest score of all tires I've had the chance to test up to now. Most other road bike tires seem to come in at 4-5 points.

The Vittoria Rubino Pro Speed offers a low weight and a low rolling resistance at the higher end of the air pressure range. This comes at the cost of a very low puncture resistance and only a thin layer of rubber. I can't imagine a situation where I would prefer this tire over a Conti GP4000S II or Schwalbe One which offer close to the same rolling resistance but offer a much higher puncture resistance.

The Pro Speed also seems to be priced higher than the usual Rubino pricing. Prices might come down a bit in the future as the new G+ tires are still new. At the moment, pricing is similar to the GP4000S II (read review) and Schwalbe One (read review) which should last just as long or maybe even slightly longer. I rate this tire 4/5 recommended because it does offer a very low rolling resistance which is what it promises.
