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 27% while driving a Toyota Perodua Myvi Toyota Passo (195/55 R15) on mostly motorways for 0 spirited miles
Honestly, i did not research anything prior to this incident. I spun my car and rammed into the side wall one a ram going up the highway. It was a rainy day, where i was travelling around 50-60km/h. VERY BAD WET TRACTION.

I recommend to search other tyres as its not worth it in any occasion.

Got these stock fitted. These tyres are good for normal driving below 120km/h. On wet road, bad grip. Very dangerous to use on wet road above 60km/h. Its cheap an economical, saves fuel. Buy these if you need short-term tyres.

Got them second hand. Dry grip is acceptable. Spun my car today in the rain making a larger u turn. No grip at all during rain, total disaster and dangerous to be fitted on any cars.

Given 41% while driving a Kia Motors Forte (215/45 R17) on a combination of roads for 0 spirited miles
these tires camestock for my first car. i was clueless back then and used these impending doom tires for 3 years until they were worn. dry grip is fair. wet grip is absolutely horrible. i was driving 40 km/h on a wet road and my car slid to the opposite lane when taking a corner. that, and other numerous incidents. switched to PS3, felt more confident and understood about tires more.

cheap rubber, only possible use is to burn them on track during dry condition

Given 43% while driving a Daihatsu Perodua Axia (185/55 R15 V) on mostly motorways for 0 average miles
These tyres were fitted new in my car 6 months ago. But the rear tires began to exhibit a slight bulge that caused the tires to go out of shape. Prior to that, these tires do not perform well at all, they are loud and extremely harsh.

Given 21% while driving a Kia Motors (225/45 R17 W) on a combination of roads for 15,000 average miles
I finally got rid of these tyres which came with my car. Around 30,000km in and 2 years. It ended with a puncture, one side wall crack, one side wall already cracked (replaced with spare), and one tyre with a bubble about to explode. Ask the while dealing with poor grip and noise. I don't know what's up but i don't see how these tyres are allowed to be sold.

this is my stock tyre..very dangerous on wet road, my car had slipped numerous times during rainy day, even in moderately hard breaking under 50 kmh, even for an economical tyre, not worth your family safety, plus very noisy especially on highway..changed to michelin, felt safer and confident in breaking and cornering but very expensive!!!

Given 43% while driving a Renault Clio 1.6 16v (225/45 R17) on a combination of roads for 130 easy going miles
I have had 4 Synergy M5's fitted recently. Today was the coldest day since last winter in the UK & at 7.45am the temperature was -0 with black ice on treated roads. I can confirm that these tyres are not good atall in these conditiions with my vehicle constantly loosing tractirebberon at relatively low speeds & on straight roads. I had to reduce my speed to around 40mph for self preservation which meant I had heavy goods vehicles having to overtake me.

Using Silverstone M5 in my Forte. Noisy and hard tyre. Wet drive is good with or without stability control. Will not change to this brand again. But good for long term use with sacrifice in comfortable. I will go for Michelin tire which i use in my previous car. Michelin make differences with just two tires replaced.

Given 44% while driving a Mazda MX5 (205/45 R16 W) on a combination of roads for 15,000 average miles
Tyres have very little grip in wet, aquaplaned into side barrier writing off front of vehicle. Tyres telegraphed nothing of pending doom. I ended up being a passenger. Better dry grip however had rear wheels slide in dry with little effort whilst cornering. I only drive a 1.6ltr hence god help those with more power through drive wheels....

My stock tyres..It has very bad wet grip and wet braking performance. Experienced nightmare with its wet braking ability. Emergency brake with just 40kmh, your car can drag very long before it comes to a complete stop. Gentle acceleration on wet road is enough to spin the tyres. Wear however is very minimum, 80% of tread when i hit 24k KM and then i change all 4 to Michelin PS3.

I have bought these tyres for my new toy car Nissan Micra, an eco car. Hence, I didn't want too much performance. just only for daily drive that's all ok for me.
Good price as well
