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 GT Radial Champiro WinterPro HP Reviews

Given 79% while driving a Ford Mondeo ST220 (225/40 R18 W) on a combination of roads for 10 spirited miles
I first fitted a set of GT-Radial Champiro Winter Pro HP's a couple of years ago and was pleasantly surprised with the all-round capabilities of the tyre, especially factoring in the price! The dry grip and handling is pretty good on these, and is certainly better than the price would suggest, but they fell a little short in the wet. I found myself backing off somewhat while cornering in the wet due to a rather understeery nature in those conditions, but by no means excessive or unpredictable.

I also had chance to use these tyres in rather bad snow and ice, and was really impressed with them in this department. These tyres got me all over the place in fresh snow, compacted snow, ice and all combinations of the above, with little effort.

The negatives of this tyre, at least for me, was the fact that they needed a LOT of balance weights to get the wheel in balance, suggesting they're not made all that precisely. And the tread blocks also wore unevenly, dispite the pressures being obsessively maintained, and with no issue with tracking or suspension geometry, etc.

I decided to go with these tyres again for the rear, so clearly I've been happy with then for the price!

it has balance problems. it requires lots of extra weight to balance the wheel. the car grips both in the dry and wet conditions well. i havent tested in snow yet but the design of the tyre gives an idea. the category c is the exact point of this tyre. not the best but if you compare with the other tyres, the price is very good.

Have not driven extensively in heavy snow, but some snow and slush as well as ice. Great tire and would be a great all weather tire all year round.

Love these things. Put them on my Passat W8 and it's a beast in the snow. I bought used (one year old). I'd buy again. Driven in deep snow (6 inches) and excellent side grip (minimal sliding).
