A time trial tire in our 2025 road tire group test? The Continental GP 5000 TT TR is a dedicated speed specialist, but can it hold its own against more traditional race tires, or does the low rolling resistance come at the cost of grip and puncture protection? We put the TT specific tire to the test to find out. Here’s what you need to know.

Originally designed for pure speed in time trials and triathlon events, the GP 5000 TT TR has since gained a strong following among pros and performance-focused amateurs on standard road bikes, too. That’s because Continental have stripped this tire down to the bare essentials, disposing of anything that might cost unnecessary watts. The result? A minimalist construction with an ultra-thin tread and virtually no added puncture protection. At just 243 g, it’s the lightest tire on test, significantly undercutting the average tubeless models by nearly 40 grams. Visually, it’s almost identical to the popular GP 5000 S TR, though the TT version is exclusively available in 28 mm wide, underlining its uncompromising performance-first approach and a key reason behind its featherweight build. But does this pared-back design compromise its versatility on the road?

High on Performance – The Continental GP 5000 TT TR in our 2025 Road Tire Test

Our test revealed the full extent of the GP 5000 TT TR’s single-minded pursuit of speed: it’s ultra-light, incredibly snappy off the line, and blisteringly efficient at high speed, or, as our tester Jan put it after just one lap, “fast as fuck.” With a lab-measured rolling resistance of just 10.4 watts, it’s the fastest tire in the test field, edging 0.6 watts ahead of the GP 5000 S TR and a full 1.6 watts clear of other top-tier race tires. But such an uncompromising design doesn’t come without trade-offs. While the TT TR offers decent overall grip, it lags behind the test winner GP 5000 S TR and the Schwalbe Pro One TL, particularly during hard braking and tight cornering. Skilled riders will cope with this without issue, but less experienced cyclists might find it a little unnerving. On the flip side, it’s handling through corners is a real highlight, offering a direct and precise response without ever feeling twitchy. The TT TR delivers excellent road feel and a lively ride.

Despite its skinny 28 mm design, the tire feels surprisingly supple and comfortable. This is largely thanks to its ultra-thin sidewalls and the actual measured width of 30.5 mm on our HUNT 40 Carbon test wheels. When it comes to rougher terrain like gravel or cobblestones, the TT TR quickly reaches its limits. Its compliance remains acceptable, but lacks grip – unsurprising for a time trial tire, which really has no business venturing beyond the confines of smooth tarmac. As with all Continental tires on test, fitting it is refreshingly straightforward. The TT TR slips on easily, seats with a satisfying “pop” and seals perfectly, even without sealant. Finally, puncture protection is a common weakness amongst most TT tires. However, the GP 5000 TT TR surprised us here too. Despite its stripped-down construction, it performed just below average in our group test, easily outperforming tires like the Pirelli P ZERO TLR RS and Specialized RapidAir TLR.

Conclusion on the Continental GP 5000 TT TR

The Continental GP 5000 TT TR is the fastest tire on test and impressed us with a surprisingly fun character and decent puncture protection for such a lightweight, efficiency-focused model. Add to that its easy installation and sleek, fast look, and it’s a top pick for both racing and time trials. That said, if you’re after maximum performance with added grip and better puncture protection, the barely slower GP 5000 S TR is the smarter all-round choice. But for those chasing every last watt, the GP 5000 TT TR remains the ultimate choice.
