Battlax BT 015

Pros, cons & observations

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.

Tire A Spirit ST

Pros

  • Excellent grip in dry, cold and wet conditions, with confidence-inspiring braking and wet-weather performance, and capability extending to occasional track use
  • Stable, predictable handling at high speeds and under heavy loads (pillion and luggage), with a comfortable ride and low noise
  • Good tread life reported by several riders, who describe even wear, resistance to squaring off and mileage up to nearly double that of Michelin tyres

Cons

  • Wear complaints from a minority, including one rider who got only about 2,000 km
  • Reluctance to turn in fast direction changes and a lack of feedback from the tyres, according to one reviewer
  • Front tyre vibration and shaking over 60 mph on one BMW K1600GT, which persisted after rebalancing at two garages

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
