The Tire Reviews Score is the most comprehensive tire 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 tire 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 Toyo NanoEnergy 2 Reviews

Given 19% while driving a Fiat Stilo (195/65 R15) on mostly country roads for 5,000 average miles
Worst tire I have ever experienced. Those were installed back in 2016 on a Fiat Stilo 1.2 5D hatchback. On dry, tires would squeal on every single corner, they felt like Flintstones cement tires! On wet... well... The ABS would kick in with MINIMAL application of the brakes feeling every single time that you might lose control altogether. The factory fit Bridgestone Turanza ER30 even after 7 YEARS and 60.000km felt MUCH better in similar conditions. It was the first time I had to throw away my tires in less than 2 years. Bought some cheap Petlas Imperium PT515 as a stop-gap but I tell you even those cheap turkish tires were LIGHT YEARS better compared to this JOKE of a tire Toyo managed to create. If you ever come across a used cars with these tires THROW THEM TO THE GARBAGE AS SOON AS POSSIBLE.

Given 64% while driving a Opel Corsa C (225/45 R17) on a combination of roads for 21,000 average miles
On dry roads the grip is satisfactory but when it changes to the wet the tires attitude you drive like a soapy road.Ä°t is a little dangerous to break and grip on wet.Wear is good.Noise and comfort are moderate.As result i do not buy it again and do not recommend to anyone.

Satisfactory grip to dry roads, poor wet performance, the factory-mounted Michellin was much better

Given 84% while driving a Hyundai Accent (175/65 R14) on mostly town for 11,000 easy going miles
Very comfortable tire, will definitely go back again. The grip during dry and wet is superb. Not noisy at all and very comfortable. Will suggest it to small passenger cars.
