Continental Grand Prix 5000 S TR Tyre Review for Triathletes 2026
The Continental Grand Prix 5000 has been the gold standard road tyre for years. The S TR (tubeless-ready) variant doubles down on that reputation — lower rolling resistance, better puncture protection and genuine tubeless compatibility make it the benchmark tyre for triathlon training and racing in 2026.
Two Versions: Which One?
Continental makes two tubeless-ready GP 5000 variants for triathletes to consider:
- GP 5000 S TR — the all-rounder; BlackChili compound, 23/25/28/32 mm widths, 320 tpi casing. Best for training, sportives and longer triathlon courses. Check price on Tredz. Affiliate link.
- GP 5000 TT TR — the race tyre; lighter casing (440 tpi), slightly faster rolling. Available in 25 mm. At £86.99 per tyre it’s race-day-only money. Check price on Tredz. Affiliate link.
Key Specifications (S TR 25 mm)
- Compound: BlackChili — Continental’s highest-grip, lowest-rolling-resistance compound
- Casing: 320 tpi — supple, fast
- Protection: Vectran Breaker puncture belt
- Recommended pressure (tubeless): 70–90 psi for a 70 kg rider on 25 mm
- Weight: approx. 265 g
Running Tubeless vs Clincher
For training, run the S TR tubeless with sealant — you’ll lose almost no punctures to small road debris, rolling resistance drops by 10–15% vs a butyl inner tube, and comfort improves noticeably at lower pressures. For racing, the GP 5000 TT TR tubeless with nitrogen-inflated sealant is about as fast as any road tyre gets outside of full disc aero wheels.
Longevity
The S TR rear tyre typically lasts 4,000–6,000 km before the tread wears through. Front tyres last considerably longer. At that mileage it’s competitive value against cheaper tyres that require tube replacements every few hundred kilometres.
Verdict
If you do serious training volume on the road, the GP 5000 S TR is the tyre to fit and forget until it wears out. The TT TR is only worth the premium for A-race days when every watt matters.
