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.

Top 3 Westlake Sport SA37 Reviews

Given 55% while driving a (205/45 R16) on mostly country roads for 10,000 spirited miles
Had to replace it pretty early due to a sidewall bump but these budget had very good dry grip when I first purchased it. However with wear the grip falls off quicker than expected, I wouldn't recommend trusting it in the wet. Pretty bad in terms of Comfort and Noise. If you need some cheap tyres with good grip temporarily until you get something, these will do the job.

Given 84% while driving a Toyota Camry (215/55 R17 V) on mostly town for 1,000 average miles
First, I'm not confident for the China made tyre after too many rumors heard from online and offline. When comes to tyre replacing time, I choose to give it a try all because of the costing matter. The all-in cost of a tyre I bought that made in PRC are almost 1x times lower than the Bridgestone Turanza retail price in Malaysia. After 1500km traveled and tested, first I realized the steering feedback are excellent for the front wheel. Even though only two pics of it for the front wheel, the braking for both dry and wet surface shown good result. The cabin sound slightly higher than before maybe it generates from the thick tread of SA37 which I'm not mind. At this trip I tried high-speed cornering when downhill, the grip are way better then before. Not much different on the ride comfort. After 10000km I'll rotate the front and rear wheel to test on the acceleration due to my car are a heavy duty rear wheel drive platform.

Given 46% while driving a BMW 118d (225/45 R17) on a combination of roads for 900 average miles
Very budget tyre and the price suits its quality, ideal for a family runabout that does not stretch its performance levels as frankly its dire and will find yourself in a ditch with any reaql load of power

Given 94% while driving a Volvo C30 T5 (215/45 R18 W) on a combination of roads for 4,000 average miles
Pretty amazing how they are. I bought these tyres because I thought I would change the car soon, so why to spent a lot of money?..., but after a couple of month using them, they perfomed really good. Not tasted in wet or winter conditions, so waiting for that. In dry they are awesome. Of course I did not change the car yet...
