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 Tyre Test Results
The Goodride Zuper Snow Z-507 was the cheapest Central European friction tyre found on the market when the test started, and with that price comes performance that can almost be said to over-perform given the cost. It rolls genuinely lightly, achieving excellent fuel efficiency that nearly matches the test leaders. However, grip-wise it's poor, delivering inadequate ice performance and merely acceptable snow grip - well behind the leaders in winter conditions. On bare pavement, the performance is a mixed bag - aquaplaning is reasonable, and it doesn't completely fall apart on wet or dry roads, but it lacks the precision and confidence of better tyres. The comfort is mediocre and stability unremarkable. For drivers in southern Sweden who primarily drive on motorways and rarely encounter snow or ice, needing winter tyres mainly for the occasional snowfall, this budget option might suffice. But for anyone who regularly faces genuine winter conditions, the poor winter grip makes this a false economy. You get what you pay for, and while it avoids being catastrophically bad, it provides minimum acceptable performance at a minimum price.
17th/18
Good dry braking.
Poor drivability in the dry, weak in the wet, very weak on snow, worst wear in the test.

Latest Goodride Z507 Reviews

Given 76% while driving a Lexus GS (235/45 R18) on a combination of roads for 6,000 spirited miles
I have these tires on my rear-wheel-drive Lexus GS. I'm pleased with the traction in winter conditions. I previously had Yokohama winter tires and didn't notice much difference. The only downside is increased road noise. I recommend these tires and would definitely buy them again.
