Tufo Thundero HD 700 x 48c Review

I purchased and installed a set of Tufo Thundero HD 700 x 48c tires (beige) in late May, 2025.

My initial impression upon unboxing was pleasant as the casing consistency, tread geometry, and return to shape were all excellent. Among the tire brands I’ve used, the ranking for initial impressions would probably go:

1. Tufo (2025)
2. Continental (2024)
3. American Classic (2024)
4. Maxxis (2022)
5. Kenda (2023-2024)

The tires were installed tubeless onto Spinergy GX Max wheels (hooked aluminum in rim with 24mm internal width) with Reserve Fillmore valves and Silca Ultimate Tubeless Sealant (2025 version). Installation difficulty can vary wildly depending on tape installation, equipment used, experience, etc, but I will say the tires fit my rims fairly snug and beading did require a short blast using an air compressor after failed attempts with a floor pump. A bit of sealant escaped in the process, prior to the tire beads seating, but after that instant, zero bubbles or leakage has occurred in four months of use. No tire/tread wobble was apparent as I have witnessed on other brands, with the worst being Kenda. The initial width at 50 psi (3.45 bar) on my rims was 47.5mm as shown in the images.

Against all traditional logic, but with great confidence given by initial impressions, my first real ride on the tires was a loaded, three-day, 160 mile, mixed surface bikepacking trip that traversed Pennsylvania’s Michaux State Forest. The full loadout weight (bike + rider + gear + water) was 310 lbs (141 kg). On pavement the new tires exhibit an audible, but not unpleasant whine. The scale-like center tread rolls quite well on hard surfaces, accepting both acceleration and braking inputs predictably and efficiently. The 48mm width offers the option for great comfort by tweaking your pressure as the sidewalls aren’t overly stiff. Overnight rains provided good tests on wet, packed gravel, an MTB singletrack descent, and damp grass. Traction was exceptional on the first two surfaces, with braking modulation and lockup being tactile and predictable. The tire easily endured several pings when rolling/slipping off of sharp rocks and roots. I was amazed how the corner knobs were unscathed – especially considering the loadout. As one may expect, traction on wet grass was lacking. Luckily, that is not a typical requirement for a gravel or bikepacking tire in my region. Upon returning home from the trip and cleaning the bike, the tires cleaned well and looked nearly unused.

I have ridden an additional ~500 unloaded miles including all manners of gravel chunk, tar and chip, pavement, dirt, sand, and mud with no issues or leakage. The tires do have some slices in the center tread that are likely from braking lockups on rocky mountain bike trails. These cuts do not seem to affect anything as of now. I also have one small gouge that runs from the corner knobs onto the sidewall, but see no major concern with it.

Overall, I feel these tires are the perfect match for the riding I do thanks to the width, reinforced casing, good road performance, and strong cornering knobs. They have endured punishment that typically requires a hundred more grams of weight penalty to survive and have performed exceptionally on the load-bearing and traction front.
