This is the first used mountain bike tire I'm reviewing, it was used as a front tire for 3000 km. Wear of the central knobs is 0.3-0.5 mm, wear of the shoulder knobs is pretty much zero. This is mostly because it was used only on Dutch trails, which are very easy on tires (we have no rocks). These tires were donated to me by an MTB buddy. He upgraded from a Nobby Nic/Racing Ralph combo to a tubeless Rocket Ron/Thunder Burt Evolution set up. He had to do this because he couldn't keep up with me anymore after I upgraded my rear tire to a tubeless Race King RaceSport.
The 2012 model year Nobby Nic Performance was a single compound tire, this compound was called ORC (Off-road Racing Compound). Starting with the 2013 model year tires, Schwalbe started using a dual compound on the Performance line tires. I'm looking forward to testing a new Performance line Schwalbe sometime soon. Just like the Racing Ralph Performance, this Nobby Nic was very easy to mount as well. it's very easy to get the bead over the rim walls, the Evolution line beads definitely are much tighter.

Size and Weight Measurements
|Size and Weight Measurements (Bike Wheel: 622-17C, Pressure: 35 psi / 2.4 bar)|
|Specified Weight||600 grams|
|Measured Weight||605 grams|
|Measured Width Carcass||54 mm|
|Measured Width Tread||55 mm|
|Measured Height||54 mm|
|Measured Knob Height Center||3.2 mm|
|Measured Knob Height Edge||5.0 mm|
|Measured Total Thickness Sidewall|
|Measured Total Thickness Center (excluding knobs)|
Because this is a used tire, some measurements will be off when compared to a new tire. The measured weight is 605 grams, I'm not sure what the original specified weight of the ORC Nobby nic was, but 605 grams isn't bad. The size of the carcass is very close to the size a 2.25 sized tire should have. Height of the center knobs is 3,2 mm. I think this should be 3,5 - 4 mm for a brand new Nobby Nic. Knob height at the edge of the tire is 5 mm.
Rolling Resistance Test Results
|Rolling Resistance Test Results (Speed: 29 kmh / 18 mph / 8 m/s, Load: 42.5 kg / 417 N)|
|Inner Tube||Conti MTB 29 (225 gr butyl)|
|Rolling Resistance 55 psi / 3,8 Bar||
|Rolling Resistance 45 psi / 3,1 Bar||
|Rolling Resistance 35 psi / 2,4 Bar||
|Rolling Resistance 25 psi / 1,7 Bar||
|Use the formula: RR (watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load|
Although this is a used tire and wear is very low, the rubber did age for 2.5 years so take this into account. Rolling resistance is not bad at all for a tire with big knobs, the Nobby Nic even beats the top of the line Maxxis Ikon 3C MaxxSpeed, which has much smaller knobs. Rolling Resistance is 3 - 5 watts higher than a Racing Ralph Performance of the same age and mileage.
Puncture Resistance Test Results
|Puncture Resistance Test Result (higher is better)|
|Puncture Resistance Tread||12|
|Puncture Resistance Sidewall||Not Tested|
Puncture resistance is very good, with a score of 12, it's the most puncture resistant tire tested to date.
Considering it's medium price range and big knobs I think performance is decent, especially when you factor in that this tire has been used for 2.5 years. I believe tires get slower as they age because of the hardening of the rubber compound. After only 2.5 years, this effect might be quite small. Unfortunately, this is an experiment that can not be done in a day. Puncture resistance is very good, much better than the other tires.
I think this tire proves that tread pattern doesn't completely determine the rolling resistance of mountain bike tires. The Nobby Nic, with its coarse tread pattern, has less rolling resistance than a Maxxis Ikon MaxxSpeed, which is a tire with much smaller and lower knobs.
