Goodyear Drops Its Fastest Road Tire Ever: Eagle F1 SuperSport RS Reviewed

Goodyear just dropped its most significant road bicycle tire launch in years, and the numbers are genuinely impressive. The new Eagle F1 SuperSport RS and Eagle F1 RS — announced July 31, 2026 — represent a generational step forward in the brand's Ultra High Performance road tire lineup, and the claimed performance figures are hard to ignore.

If rolling resistance is your religion (and if you ride seriously, it probably should be), listen up: Goodyear claims the new Eagle F1 RS delivers a 32% reduction in rolling resistance compared to the outgoing Eagle F1R, translating to a 4.8-watt reduction at 72 psi. For context, aero gains that cost you four watts in drag savings would typically run you hundreds or thousands of dollars in a new frame or wheelset. Here, you're looking at a tire change.

What's Actually New Under the Tread

Goodyear's engineers built these tires around three core technologies that work together rather than independently.

First is the Advanced Profile construction — a non-overlapping double-layer casing architecture with a reinforced shoulder turn-up and extended tread profile. By eliminating traditional casing overlap within the main contact patch, the tread deforms more efficiently under load. The practical result is lower hysteresis, which means less energy lost as heat during each tire revolution.

Second is the Power Tensile polyamide casing material — a higher-modulus construction that keeps the tire shape more consistent under cornering loads. Consistency here means predictable grip, which matters far more than peak grip when you're descending at 60 km/h.

Third is the UUHP (Ultra Ultra High Performance) compound — a new rubber formulation that Goodyear says delivers improved wet-weather adhesion alongside the rolling resistance gains. Wet grip and rolling speed have historically been a trade-off. Goodyear is claiming they've meaningfully narrowed that compromise.

Two Tires, Two Roles

The SuperSport RS sits at the top of the lineup as the pure race-day weapon — no puncture protection layer, minimum weight, maximum speed. Think criteriums, Gran Fondos with fast finishes, or the 20-minute morning blast when you want to feel what "fast" actually feels like.

The Eagle F1 RS is the all-arounder. It carries the same Advanced Profile, Power Tensile casing, and UUHP compound as its sibling, but adds R:Shield puncture protection. You still get the 32% rolling resistance reduction. You also get the confidence to ride through gravel patches and broken chip-seal without treating every pothole like a minefield. For most enthusiast riders doing training rides mixed with race days, the F1 RS is the smarter long-term investment.

Both tires drop 23mm sizes entirely — a clear signal about where the industry's rim and tire width consensus has landed. The widest wheels are now standard, and 25mm is the new narrow.

The Context: Why This Matters Now

Goodyear re-entered the bicycle tire market seriously about a decade ago, and the Eagle F1 series earned genuine respect — winning Editor's Choice awards and appearing on WorldTour bikes. The brand manufactures its bicycle tires at a dedicated factory in Taiwan, which allows for tighter quality control than outsourced production.

The timing of this launch is notable. It arrives just as the professional peloton heads into the Vuelta a España, where riders will face sustained mountain days and the kind of high-speed descending where tire confidence is everything. Expect to see these tires on pro bikes before the race ends.

What This Means for Your Riding

A 4.8-watt rolling resistance saving is not marginal — it's the difference between sitting on a wheel and slowly drifting off it over a 3-hour ride. But the number only matters if the tire is properly set up. Run tubeless if your wheels support it (and most modern road wheels do): you'll gain an additional 1-2 watts versus the tube-type version, and you can safely drop pressure to 65-70 psi on 28mm tires, which improves vibration damping without sacrificing speed.

The Eagle F1 RS is available now at goodyearbike.com. If you're due for fresh rubber before your next big event, this is a genuinely compelling option — and one of the more honest performance claims to come out of a tire launch in recent memory.
