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 Nexen N'Fera Sport SUV SU2S represented something of an eye-opener for the test team, showing significant improvement over previous Nexen products while landing in a tie for fifth place. The Korean manufacturer has clearly addressed many prior criticisms, delivering impressive objective performance in braking and hydroplaning resistance. However, the tire still lagged behind the leaders in subjective handling characteristics, with testers noting a spongy feel with poor response and diminished stability that made the vehicle feel disconnected from the road. Interestingly, the historically budget-oriented brand has now priced itself alongside premium competitors, reflecting the costs of their performance improvements but losing their previous price advantage.

Latest Nexen N Fera Sport SUV Reviews

Given 10% while driving a Kia Motors EV6 GT (235/55 R19) on mostly country roads for 16,000 easy going miles
Out of four of these on a KIA EV6 with road noise suppression foam, three have failed at 16000 miles, resultant vibration makes the vehicle undriveable above 35 mph. They have got to be changed now at significant cost, stuck to main brand tires and avoid these at all costs. KIA were being cheap using these on a £52000 vehicle.
