Continental Ultra Sport III road bike tire on a rolling resistance test machine

The Continental Ultra Sport III replaces the Ultra Sport II as Continental's cheapest road bike tire. We tested the Ultra Sport II back in 2015 and found it to offer a lot of value for your money as it offers just slightly less performance when compared to more expensive tires. Over the last 5 years, the Ultra Sport II has been the only tire in the lowest price range that we recommend (rating of 3 / 5 or higher).

The updated Ultra Sport III is still very similar to the Ultra Sport II (read our review). The most obvious change is the new tread pattern of the Ultra Sport III that gives it a more modern look and feel. Also new is an E25 rating for use on E-Bikes with a maximum speed of 16 mph / 25 km/h. Unchanged is the 3/180 casing and PureGrip compound which both are ranked just behind Continental's 3/330 casing and Black Chili compound.


Just like the Ultra Sport II, the Ultra Sport III doesn't have an additional anti-puncture layer under the tread which is something we see more often on cheaper tires. Some of this is made up by the thicker 3/180 casing that offers a bit more protection when compared to the thinner 3/330 casing that's used on Conti's more expensive tires. The biggest drawback of the 3/180 casing is a higher weight and a higher rolling resistance.


This is a test of the 25-622 folding version of the Ultra Sport III. An even cheaper wire bead version is available as well but we always recommend the folding versions as it saves you ~200 grams for a pair of tires at very little additional cost.

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


  • Continental Ultra Sport III
Performance compared to all other road bike tires
(100% is fastest - lightest - thickest - strongest)

It's quite obvious from our test results the only change made to the Ultra Sport III is a new tread pattern and an E25 rating. While no improvements have been made that show up in our tests, the Ultra Sport III still offers the most bang for your buck when we compare it to other tires in the lowest price class.


When we compare the Ultra Sport III to Continental's top of the range Grand Prix 5000, rolling resistance of the Ultra Sport III is 40% higher, weight is 20% higher, and puncture resistance is the same. In terms of price, it looks like you can buy 2 Ultra Sport III's for the price of a single Grand Prix 5000 (read our review). We leave it up to everyone to decide whether that performance difference is worth it.
