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.

Auto Express says the budget Triangle is better than a summer tyre in snowy conditions but warns that it is “worryingly poor in the wet” and that buying it “is false economy”. Its snow performance is acceptable, but its weak wet grip and high running‑costs undermine its low purchase price.

The Triangle WinterX TW401 receives a poor rating for driving safety due to its significant weaknesses on wet roads, despite decent performance on dry and snowy surfaces. It offers satisfactory feedback and precision on dry roads, with good control at its limits. However, on wet surfaces, it has a very low grip level and a tendency to understeer or oversteer early, resulting in poor handling. Its braking performance is also only just satisfactory, and its aquaplaning resistance is poor. On snow, it performs well with good braking, traction, and handling. Its environmental performance is average, with a satisfactory lifespan and low abrasion, weight, and fuel consumption, but negative marks for manufacturing residues on new tyres.

Latest Triangle WinterX TW401 Reviews

Given 36% while driving a Volvo v70 D5 (205/55 R16) on mostly town for 5,000 average miles
TW401... This tire is ok on dry frozen asphalt, not too bad at a thin layer of fresh snow, but in everything else (wet, dry with warmer temperatures, a bit more snow like 2cm+ and it doesn't matter if it's wet snow or dry) it's garbage. 0 confidence compared to Hankook, Yokohama, Sailun, Falken, Maxxis, Taurus(Kormoran)... 2nd worst i've ever driven, absolute worst was Westlake, but that was like 10 years ago. You can think if it's so bad, maybe it will last... – It doesn't, it's below average. You pay less and you get way less than expected, one of the worst value for money. This is my experience, yours could be different.

Given 58% while driving a Opel Astra G (195/50 R16) on a combination of roads for 8,000 spirited miles
after ~7000km of use - stay away from snow. 95% of the time I were driving on snow less roads. Didnt have much snow this winter but I did buy these TRIANGLE WINTERX TW401 becouse they did show good result on wet/ice in 1 and only test I found. Yes, they were realy ok on these. I knew they wont be excelent with deep snow - and I guess it right, but still driveable. My guess - after 3000km they do lose his best rubber for snow preformance. Now on the dry and wet they still ok, (the wear of fronts is 3mm). There is no way I will swap axles for the next winter. Just - keep going all summer or buy summer tires. Dont use/buy it if u are a line to line quick changer. They have soft sidewalls. I was expecting stronger sidewalls as they are made for middle europe winters. I would recomend these tires for down side england or channel island weathers in winter.
