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.

Latest Dunlop Direzza ZIII Reviews

Given 76% while driving a Subaru BRZ (225/45 R17) on track for 5,000 spirited miles
An excellent 200tw alternative if you want a good do-everything tire. The tire won't win competitions without compromising wear, but if you have seasons in your region, the Dunlop handles consistently well in the wet and high grip in the dry with a linear fall-off of grip in high speed cornering. You'll have consistent times until the start to grease up and then you just do a cool-down lap or two and you're ready for another attempt at your PB. It's not a good AutoX tire (unless you're in some place consistently hot like California or Mediterranean because it takes too long to heat up, get to temperature. Its a fun, inexpensive (relatively) tire for learning on that will get you ready for a faster tire like the Falken RT660 or Yokohama AO52 or Nankang AR1. Wear isn't bad either if you have a good alignment and flip/rotate tires regularly.

Given 80% while driving a Lexus LS400 (/40 R17) on track for 0 spirited miles
These are our "baseline" tires for our 24hrs of Lemons Lexus LS400 (we run 255 in the back). They wear great, are predictable and super easy to drive on, while not being the fastest unfortunately as we are otherwise very happy with them. Good for about 1000 race miles on our car, though we put new ones on each event.
