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.

Low price and costeffective tyre. Half the price of premium brands. Very good performance in snowy conditions, good in dry conditions. wet road performance is average. Wear is mediocre. The noise level is at medium levels, but it gets louder as it ages. I think this tire has two major weak points; The first is avaragr wet handling, and the second is that it belongs to an unknown and unknown brand. But just because it's not recognized doesn't mean it's a garbage tire. Because this brand is a brand that can produce tires for heavy military vehicles and planes... I have been using Petlas winter tires on my vehicles of different brands since 2010. I bought my first petlas winter tire on the recommendation of my mechanic. I had my doubts at first. After a cold and snowy winter, I changed my mind, I was satisfied. After that, I started to prefer tires of this brand. So I've had a lot of experience with this brand. I have used it in many vehicles such as Ford mondeo, Renault clio, skoda octavia. I used it carefully in wet conditions and had no problems. I highly recommend it to those who do not want to spend double the money on premium brands.

Given 60% while driving a Skoda Citygo (215/65 R17) on mostly town for 2,040 average miles
My car is a Skoda Kodiaq. I bought it in 2017. I used it with a separate set of wheels. My storage conditions are perfect. These are my first snow tires for this car (2040 km). I used them at the end of 2024 (16590 km). I can say there is no excessive wear (tread depth).
For two years, their performance in snow and wet conditions was average. After that, they hardened quickly. Noise increased. Road grip decreased. I used them with caution, especially in puddles.
Still, I used them on the roads between Bolu, Turkey - Abant and Kartalkaya. They didn't let me down in the snow. I didn't use chains.
A good price/performance product.

Given 96% while driving a BMW X5 3.0d Sport (225/45 R17) on mostly country roads for 60,000 average miles
Petlas is a Turkish brand and manufacture tire, petlas mainly equips aviation tires for the Turkish army, so basically Turkish petlas = French Michelin, it's clear Petlas is not a tire known in Europe for this. is a not too expensive tire which does not mean bad tires

Given 58% while driving a Suzuki Jimny (205/70 R15) on a combination of roads for 1,500 average miles
This tyres have indeed just average performance on packed snow and ice as the manufacture suggests. However they are terrible when it came to the sidewall stability and running at speed on highway. In just 50-60km wind and running with anything above 70km, the car bounces scary all over the road with a 70mm tall sidewall and that became critical when the temperature rises to 7-8 C degrees. The lateral stability is not that good either, when on tracks in packed snow a 4x4 goes side to side more than a street car does on good tyres. I do not recommend this, for just a few more you can get better.

Given 83% while driving a Nissan Qashqai (215/55 R18) on mostly country roads for 3,000 spirited miles
I was reluctant to buy these as I had never heard of the brand and I always buy premium brand Tyres, mostly Goodyear. They have been a very pleasant surprise, handling well in all conditions including slush and snow. A lot of my driving is on muddy back roads and they perform very well in these conditions. Comfort and noise levels are very good, in fact no worse than the Continental tyres that came on the car. Fuel consumption has not been affected by these tyres either. Overall I can only say that I am very satisfied with these Tyres, especially considering I only paid £80 each Inc vat so they are something of a bargain. After just under 3000 miles of fairly hard driving on mostly poor quality back roads they still look like new with no apparent signs of wear.
I would definitely buy again.
