Maxxis Rambler EXO/TR 120 TPI road bike tire on a rolling resistance test machine

The Rambler is a gravel bike tire from Maxxis that should suit a large range of on- and off-road conditions. Although Maxxis is quite a well-known brand in mountain biking, they aren't that big yet in gravel bikes. The Rambler is their first tire designed entirely for gravel bikes.

Our first impression of the Rambler (looks and specifications) is positive as it looks like a well-rounded all-purpose gravel bike tire, and it's available in all of the popular gravel bike tire sizes. One thing to beware of is that Maxxis usually releases a huge amount of different specifications of the same tire, and the Rambler is no different. Be aware that this is a test of the 120 TPI "EXO/TR" version and the other versions might perform differently.


The Rambler is available in 120 TPI and 60 TPI versions and also a 60 TPI version with "Silkshield" protection which means it has a protective layer that runs from bead to bead, unlike the "EXO" protection that is sidewall only. The 60 TPI EXO/TR version comes with tan-colored sidewalls and the 120 TPI version has black sidewalls. If you prefer tan-colored sidewalls and the 120 TPI casing, that's not possible.


Maxxis did a good job with making the Rambler available in the most popular tire sizes for gravel bikes: 38, 40, 45, and 50 mm and also 47 mm for the 27.5/650b wheel size. 50 mm is a size we do not see all that often with gravel bike tires (it's getting dangerously close to a mountain bike tire) but it looks like there's demand for oversized gravel bike tires.


The compound used on the Rambler is a "Dual" compound and we're a bit disappointed it doesn't use Maxxis's 3C compound technology. Maybe the "Dual" compound is just as good but we couldn't find much information about it. Let's just put it on the test bench and see how it does in our tests.

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.

The 120 TPI Maxxis Rambler EXO/TR doesn't impress us as it lacks some speed and at the same time doesn't perform all that well in our puncture tests. We are positive about the tread profile of this tire as it looks like it will suit a very large range of conditions. A faster "3C" compound might have helped give it a bump in performance as we think gravel bike tires should have the fastest compounds to differentiate more from mountain bike tires.


If you're looking for gravel bike tires that perform well year-round, these might be fine, but you might miss that last edge in performance. As always, we recommend you to go to our CX/Gravel overview page and compare the Rambler against the competition.
