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.

4th/7
The Nankang Sportnex CR-S impressed with surprisingly pleasant road damping and moderate noise, plus nice steering with accuracy and immediate reaction. Wet track performance was its weakness with the slowest laps, longest braking, and uncontrolled sliding that demanded careful, separated inputs. Dry conditions brought substantial transformation with competitive pace, strong braking, excellent mid-corner grip, and quick, authoritative steering, though communication remained limited. On the long road course it was uncommunicative but very fast with plenty of traction everywhere—braking, power, mid-corner—but lacking the feel to combine these elements confidently. Noticeable performance drop across laps but still very capable. Wear analysis showed excellent durability with only 0.5mm loss on ribs and 1mm on outboard shoulder, among the best in the test.

Latest Nankang Sportnex CR S Reviews

Initial Impressions Review
Given 64% while driving a (305/30 R19) on for 1,302 miles
Tires lasted about 5 track days. I found heat management to be a problem. First lap is needed to warm the tires and laps 2 & 3 are fast. But starting at lap 4, the tires already become greasy. The problem seems to becomes less obviously as the tires age, but I find the RE-71RS to be slightly faster, wear at at similar pace (maybe slightly slower), and manage heat better for longer. Because of that, I would choose the RE-71RS over the CR-S. The Track Attack Pro being more expensive and wearing a lot faster takes this competitor out of the equation for me for practice, but for a competitive time attack of time trial, I would absolutely consider it. I'm putting the new RE-71RZ to the test right now also. More to come on that...
