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.

Latest Michelin XWX Reviews

Given 80% while driving a Chrysler Jensen C V8 (205/70 R15) on a combination of roads for 7,000 spirited miles
I am old enough to have driven on these tires when they were the supercar tire of choice back in the 70’s! Clearly although looking the same they have been upgraded with modern technology as they are grippier and more precise than the originals. They do sacrifice a little grip to a modern tire but as compensation they seem to give more feedback and a more progressive breakaway then is now customary. On a powerful classic car that is a good thing. Just like the originals they emit a slight whine that increases in pitch with speed - I don’t find this annoying, it adds to their authentic classic character. On wet and slippery roads they are remarkably effective with strong grip, excellent feedback and smooth breakaway. If you like driving your classic car fast you will enjoy these tires. Happily they
ride softly and quietly over bumps and best of all they have worn extremely slowly on a powerful car driven with enthusiasm. Yes they are expensive, but I really feel they offer good value for money and they look right too.
