The Tyre Reviews Score is the most comprehensive tyre 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 tyre 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 Syron tyres Premium Performance achieves an "adequate" overall rating, primarily due to its weak performance in driving safety, especially on dry roads. It nearly achieved a "good" rating for environmental performance, but its overall performance is limited to "adequate." On dry roads, it exhibits significant weaknesses, losing performance with increasing temperature, providing poor feedback, and responding slowly to steering inputs, leading to unstable handling and oversteer. Its braking distance is good. On wet roads, it achieves a "satisfactory" overall rating, narrowly missing a "good" rating for braking. Its aquaplaning resistance is only satisfactory. Its handling performance is "adequate," struggling to combine longitudinal and lateral forces effectively, leading to understeer and oversteer. It nearly achieved a "good" rating for environmental performance, but also for projected mileage. Its abrasion is rated "good." It achieves a "very good" rating for fuel consumption and performs well in weight.
14th/15
Low price, low rolling resistance.
Low grip in the wet, high levels of understeer with spongy handling, loud noise.
Not Recommended.

Given 47% while driving a BMW M2 Competition (235/35 R19) on mostly motorways for 35,000 average miles
I took those tyres on a race track day on Grobnik/Rijeka Croatia, they were overheating massively after 2-3 laps. Front pushed a lot, I had to deal with under-steer a lot. I went for tourist drives on Nordschleife/Nürburgring Germany. On the first day we had rain, shortly anything more than road legal driving pace (not on German Autobahn :) ) made the tyre act snappy and very hard to drive. Hardly any traction in straight or in the curves. Not so bad with aquaplaning though. Tyres are sort of OK for daily commuting. Wouldn't buy them, I've got them with vehicle.
