Cooper Discoverer Winter

Cooper Tyres Premium Touring Winter

The Discoverer Winter has been specifically designed at Cooper's Europe Technical Centre to meet the needs of SUV drivers during the coldest months of the year. Whilst four-wheel drive can help keep traction on slippery surfaces, it does not stop vehicles. Tyres are the vehicle's only connection with the road surface to deliver grip and stopping power, so tyre choice is critical.

Manufactured in the United Kingdom and developed using Cooper Tire's expert 4x4 and off-road knowledge, the Discoverer Winter is the result of Cooper Tire Europe's most comprehensive winter development programme to-date, having been extensively tested in a range of winter conditions. This included punishing tests of snow acceleration and braking, snow handling, ice braking and acceleration at Arctic Falls in Sweden and at Test World in Finland.

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.

Still decent braking and traction on snow. Very quiet and quite comfortable tyre.
Unexpectedly low cornering on snow with respectable traction and braking grip. Poor performance with risk of oversteer in the wet and less secure balance in dry corners. High rolling resistance.
Sufficient.

Inexpensive branded tire with a balanced performance profile, impressive suitability for snow, stable handling in the dry, short braking distances in the dry.
Average comfort.
Exemplary.

Latest Cooper Discoverer Winter Reviews

Given 76% while driving a Land Rover Freelander 2 (235/60 R18) on a combination of roads for 10 spirited miles
Compared to the all season Pirelli Scorpion and Michelin Pilot Sports I have used before I am amazed by how well these winter tyres perform. In the dry they are a
fraction less precise and grippy but only by a very small margin. Rolling comfort is a little better on the Coopers as compensation. In the wet, particularly as the
temperature drops they are vastly superior to the all season tyres with really clingy grip even on greasy surfaces with super progressive breakaway. You really can take liberties. On fresh light snow they grip well and on icy roads they retain control where normal tyres would just let go. I have not driven them on snow deeper than about 5 inches. Naturally being a low temperature tyre they wear quickly if driven at high speed in summer relative to an all-season. I fit them during the winter and use the all-seasons in summer so I get the best of both worlds. Highly recommended for winter safety and security!
