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 Yokohama iceGUARD iG65 Reviews

Toyota (205/55 R16 Q) on mostly country roads for 5,000 average miles
I want to try nordic tyres instead of european winter tyres, so this was the reason why I bought Yokohama IceGuard. Compared to the tyres from the past ( michelin A6, continental TS830, nokian w...) you can feel the difference from the first kilometer. Thy tyre is not designed for wet/dry/hot but the handling is still better then some budget class tyres, but when the real winter begins, then you can feel the difference, if you live close to the mountains or in countryside, where you have only 2-3class roads, then I suggest you to try...

I've had these fitted, now, for three Canadian winters. Consider this a mid-life/end-life review (depending if I toss them early). Snow? They're ok. Reasonable grip, reasonable clearing capability from snow/slush building in the treads. Ice? Surprisingly ok. For a winter-rated rubber, they're "as-expected". Ice really isn't fun to drive on, I've never really been caught offguard by ice on the roads, so I'd actually consider these to be pretty decent here. Dry? Mediocre-to-bad. On dry cold roads, the car slides and moves more than it should. Aggressive (or, spirited) driving is heavily discouraged by the Yokohamas and they will give-way quickly. Wet? Downright dangerous. These have got got to be one of the worst sets of rubber on a car for damp/wet/rainy/slush weather that I've ever experienced. Other comfort related notes: these tires wander in grooved pavement and brushed concrete surfaces and generally make the car feel unsettled. They provide little-to-no feedback from the front end which is exasperated by the wandering. I would not purchase again. Winter tires need to be capable in a wide range of weather from ice & snow, to wet & slush as the temperatures rise before you swap over to all-season/summer tires. The lack of traction in the rain is absolutely horrendously dangerous and forces you to drive so cautiously that you'd think you'd be on proper ice. Thankfully (or oddly) the traction in the wet, whilst braking, is not as bad as it is for acceleration/turning.

Not particular good in snow. Rather low grip in snow but much better on icy roads.
