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 Toyo 330 Reviews

Given 44% while driving a Renault Clio 1.2 8v 60hp (225/45 R17) on a combination of roads for 3,000 easy going miles
These tires are good only if you live in the desert. Bought them in the beginning of the summer, and with the first autumn rain I managed to totally smash my car and get some nasty fractures. If you expect any kind of rain in your area DO NOT BUY THESE. They have close to zero grip on wet. My car slided like it was on ice while driving with speed below 50km/h and fell out of the road. I cannot believe that toyo manifactures these. I have driven some recycled noname tyres for 15 gbp per piece back in the days that had considerably better handling on wet.

Given 51% while driving a Vauxhall Corsa (225/45 R17) on a combination of roads for 15,000 average miles
I used to have a set of 330's on the front of my Corsa, and being that I did deliveries, I was used to being out in all sorts of weather (including the snow).

In the dry, they were good, and provided good feedback.

However, in the wet, I found them to be the worst tyre I have used.

Never again shall I buy them.

Given 77% while driving a Vauxhall 1.7 TD estate (225/45 R17) on mostly country roads for 1,000 spirited miles
Huge improvement over budget tyres and reasonably priced.

Are quiet and ride very well. Good traction away from the line.

Would recommend as next step up from budgets.

Given 77% while driving a Renault Clio 1.2 mark RL Oasis (225/45 R17) on a combination of roads for 5,000 average miles
Came with a second hand car, grip is mostly ok. Wear seems ok, had the car a year and only now needing new tyres.
