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.

The GT Radial WinterPro 2 Sport fails to achieve good results on dry, wet, and winter roads, resulting in only a satisfactory driving safety rating, and also only manages satisfactory environmental performance, leading to a satisfactory overall judgment. For driving safety, the tire shows weaknesses in precision and steering feedback on dry roads, lacking the accuracy and directness expected during steering input and cornering - steering corrections are needed to maintain the desired path, and during sudden evasive maneuvers the WinterPro 2 Sport doesn't fully convince as the test vehicle tends to oversteer, especially when counter-steering, with sliding phases that could be shorter, resulting in overall limit behavior that isn't critical but only achieves satisfactory ratings for both responsiveness and limit performance, while dry braking distances are also rated as only satisfactory compared to the test field. On wet surfaces, the GT Radial also only manages satisfactory ratings, failing to achieve good scores for braking distances or longitudinal and lateral aquaplaning resistance, while its handling performance is rated as merely adequate due to poor combination of longitudinal and lateral forces, causing the test vehicle to tend toward under- or oversteering early and for extended periods depending on the curve, preventing precise control over the course with low limit performance and only adequate safety reserves. In winter conditions, the WinterPro 2 Sport also fails to achieve good results overall, though it manages good scores for snow braking and snow traction, its handling performance is rated as only satisfactory since it would need to clearly better combine longitudinal and lateral forces for more precise course control, with moderate limit reserves, and it also narrowly misses good ratings for ice braking. Regarding environmental performance, this Chinese-manufactured tire also only achieves satisfactory ratings due to satisfactory predicted mileage that impacts the environmental score, though it earns good ratings for tire wear and fuel consumption while having above-average weight.

Decent performance in braking as well as in cornering grip on wet surfaces. In dry corners at reduced grip level, easy to control. Rolling resistance and rolling noise are low.
Weak performance with significant oversteering tendency on snow, somewhat indifferent handling on wet surfaces, weak aquaplaning protection.
Good.

Latest GT Radial WinterPro2 Sport Reviews

Initial Impressions Review
Given 81% while driving a BMW E63 645Ci (245/45 R18) on for 3,000 miles
I got these to replace Dunlop winter sport 5's as they had started cracking due to age.

These have been brilliant since installation on 3.0i rwd car. Really impressed me on very slippery Scottish side streets at -7C that hardly seen much traffic.

Very comfortable compared to the runflats.

Gives me great confidence manoeuvring in the winter.

Would recommend them to anyone looking for winter tires.
