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.

Given 43% while driving a Ford ba falcon (245/40 R18 W) on track for 2,500 spirited miles
These were 9month old date stamp very understeery in the dry and massive oversteer in the wet and very loud compared to mpsc2 not worth the money IMO

Perfect tire for track days.
Not the best on wet condition but they defeat well on an heavy car like mine (e39m5).

The wear is good, they are predictable and responsive. They can compare to hankook rs4.

They are noisy and not suitable for daily driving. (I use it to go from the track to the house.. 4 hour drive and it's enough)

Given 66% while driving a Proton Satria 4G63 (225/45 R17) on track for 100 spirited miles
very noisy tires but get the job done nicely for track days. May not be suitable for daily driving as this tire is very noisy and wears very quickly but dry performance is identical if not better than many other more expensive tires.
Definitely will buy again after this set wears out.
a good alternative to Yokohama AD08, Achilles 123S and the likes

Given 87% while driving a Mitsubishi Evolution X (245/40 R18 W) on mostly motorways for 500 spirited miles
Fitted on my evo x about a couple of weeks ago. The dry grip and feedback is super awesome, much better compared to my previous set of bridgestone re003. However, the wet grip of the tyre is much inferior compared to the re003. On a damp road it performs good, similar to the bridgestone but if theres a thick layer of water on the road or its raining heavily this tyre is going to give you a heart attack. You have to maintain a max speed of approx 80-100kmh to stay safe.

A little note for evo owners, this tyre performs much better on an evo compared to Michelin Pilot Sport 4. Its mainly due to the hard sidewall of the tyre i guess. Soft sidewall tyres like the ps4 dont work too well with the evos. I tried once and sold off the ps4 a week later. It really makes the car unstable, almost feel like floating at higher speeds.
