- Vittoria Zaffiro Pro G+ 2.0 25
(100% is best)
Just like many other tires from Vittoria, the Zaffiro Pro has been updated and now uses their Graphene 2.0 compound. The Zaffiro Pro is a low price range tire positioned under Vittoria's slightly more expensive Rubino line of road bike tires. Vittoria advertises the Zaffiro Pro as a "Performance Training" tire that includes a strong nylon casing, good grip, and a long tread life.
The Zaffiro Pro looks like a decent tire as it comes with folding beads, a 60 TPI nylon casing, single compound Graphene 2.0 compound, and an acceptable weight of 280 grams for the 25-622 size. Vittoria also offers an even cheaper Zaffiro (non-Pro) that comes with wire beads, a 26 TPI nylon casing, a cheaper non-Graphene compound, and a weight of 380 grams for the 25-622 size.
As always, we recommend to at least go with the folding bead versions of the cheap tires as they are often just a slight bit more expensive and the weight savings and overall quality of the tires is definitely worth it.

| The Road Bike section is a multi tire size section, air pressures have been adjusted to the measured casing width. All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs. Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load. |

Conclusion
- Vittoria Zaffiro Pro G+ 2.0 25
(100% is best)
The Vittoria Zaffiro Pro is a decent tire for training purposes but be aware that its puncture resistance isn't any better than much faster and lighter racing tires. The main problem we see is that when we compare the Zaffiro Pro to other tires in the lowest price category, tires that perform better on our tests can be found.
When we compare the Zaffiro Pro G+ 2.0 to the more expensive Rubino Pro G+ 2.0, we see rolling resistance is pretty close between these tires. The Rubino Pro G+ 2.0 (read our review) performs a bit better in the puncture resistance tests, has a lower weight and comes with a more advanced 3C version of the G+ compound.
Another thing to watch is the 25-622 size of the Zaffiro Pro has a maximum rated pressure of just 100 psi / 7 bars which may be a bit low for some heavier cyclists.
