Tufo Gravel Swampero 40 road bike tire on a rolling resistance test machine

If you're looking for a gravel bike tire to get you through more challenging conditions, the Tufo Swampero might be what you're looking for. Tufo currently offers three gravel bike tires, and we've already tested the Gravel Speedero and Gravel Thundero, both made for lighter/dry conditions. The Gravel Swampero comes with bigger and wider spaced knobs for better off-road grip and mud-clearing.


Technically, the threesome of Tufo gravel bike tires are pretty much identical, with all three using the same 210/375 TPI casing and compound. As we found the Gravel Thundero (read our review) and Gravel Speedero (read our review) to perform very strongly in our tests, the more open tread pattern should make this a very versatile gravel bike tire.


Like the Gravel Thundero and Speedero, all sizes of the Swampero are available with either full-black or black-with-beige sidewalls. We've tested the 40-622 version with black sidewalls, which is the exact same size and color as the Thundero and Speedero we tested and will make for an excellent comparison of Tufo's gravel bike tires.

The CX/Gravel 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.

Like the Gravel Thundero (read our review) and Speedero (read our review), the Gravel Swampero performs very strong in nearly all of our tests. Of course, it's a bit slower rolling as the tread pattern simply isn't made to provide the absolute lowest rolling resistance. The main weakness with the Tufo gravel bike tires seems to be in the puncture resistance of the tread, as you'll have to rely on tubeless sealant to seal small punctures.


We also see the wet grip on a hard surface is much lower than the Speedero and Thundero, which we attribute to the higher and wider spaced knobs, which results in more flexing and reduced contact area that both decrease grip on a hard surface. The grip should be much better on softer surfaces where the knobs can dig into the surface.


All three of Tufo's gravel bike tires are excellent choices, and it will be up to the individual and the expected conditions to decide which will best suit their needs. If you're still undecided on which version of these tires will suit you best, drop over to our comparison section, where you can compare the Gravel Thundero, Gravel Speedero, and Gravel Swampero side by side.
