Higher is better. The Relative Score follows your weights below; category scores do not change.

Weight the categories that matter to you

Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.

Pros, cons & observations

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

Tire A Courser CXT

Pros

  • Long tread life with multiple users reporting over 50,000 to 68,000 miles of use
  • Surprisingly low road noise and smooth ride for such an aggressive tread pattern
  • Excellent traction in diverse off-road conditions including mud, dirt, and heavy snow

Cons

  • A slight road hum or howl is present at highway speeds, as expected from an aggressive tire
  • Heavier load range options (such as Load Range E) inherently provide a firmer ride
  • Limited long-term data for some users who installed them very recently

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.
