The Tire Reviews Score is the most comprehensive tire scoring system available. It aggregates professional test data from multiple independent publications, user reviews, and consistency analysis using Bayesian statistical methods, weighted normalisation, and recency-adjusted scoring to produce a single, reliable performance rating.

Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tire tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

2nd/7
The Vitour Tempesta P1 P-01R delivered a firm but cushioned road ride with well-managed noise and progressive steering buildup. Wet track performance was frustrating with razor-sharp but unhelpful steering, a rear prone to stepping out, difficult power delivery, and the longest braking distances with slow recovery. Once dry, it transformed into the fastest tested with strong mid-corner grip, very quick steering, the best dry braking, and excellent corner exit power delivery that rewarded smooth inputs. On the long road course this debut tire was capable but selective—braking was notably strong and lateral traction decent, but combining inputs felt unnatural with front-end push under acceleration if steering wasn't finished. Consistent after the first lap with second-fastest average times despite not feeling the best to drive. Wear showed 2-2.5mm loss on outboard shoulder with noticeable 1mm loss on intermediate ribs.

Latest Vitour Tempesta P1 Reviews

Given 80% while driving a BMW M3 (275/35 R19) on track for 2,000 spirited miles
The P1 is a really nice steering tire, and if you get it in the right window, it's fast. But on my vehicle, it overheats very quickly. A good autocross tire, but not a good track day tire.
