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.

The LASSA SNOWAYS 4 provides good steering feedback and precision on dry roads, with satisfactory limit behavior and good braking performance. On wet roads, it performs well in braking and aquaplaning tests but lacks the precision needed for a good handling rating. On winter roads, the tyre struggles, earning only satisfactory ratings in braking and traction tests and a poor rating in handling. It loses traction early and has a narrow limit of safety, making precise maneuvering difficult. Ice braking performance is also only satisfactory. Environmentally, the tyre narrowly misses a good rating. Its projected lifespan and wear are rated as good, but its high weight results in only a satisfactory efficiency rating.

Top 3 Lassa Snoways 4 Reviews

Given 87% while driving a Hyundai i30 (185/65 R15) on a combination of roads for 4,000 average miles
I purchased these tires this winter and have been very impressed with their performance. They provide excellent grip on both dry and wet surfaces, as well as on the light snow we experienced this season. I tested their limits and found that they only begin to exhibit slight understeer when exceeding the speed limit by 50% in corners. These tires are ideal for drivers who prioritize a defensive driving style.

Given 88% while driving a Mercedes Benz E220Cdi (245/45 R17) on mostly motorways for 12,000 average miles
I was skeptical at first. The tire looks heavy but surprisingly it is consuming less fuel than the goodyear asymmetric 3(which are completely garbage).
I am very satisfied so far, I have not tried them on snow and ice yet. I would buy them again.

Given 77% while driving a Ford Focus MK2 1.6TDCI 2008 2011 (205/55 R16) on a combination of roads for 9,942 average miles
First of all, I would like to express that I am satisfied with the Lassa Snoways 4 series, which I have been using for 2 seasons. The wear rate is less than I expected, yet it is around 10-15%. I did 16000km in 2 seasons. In terms of where I live, it did not upset me once in the harsh and harsh winter conditions. Of course, my vehicle has a great effect on this, but the tires surprised me. It greeted me as a tire that has successfully managed to climb even on hard snow with a bottom of about 30 cm. My vehicle is front-wheel drive and even though I had a sinking problem, it was able to oscillate without skidding too much. I provided a rating, but if I were to give an average score, I would say 10/8 by adding price/performance. Their patterns work well at keeping snow. When the vehicle tends to slip, the tires do not directly stop holding onto the road. If you are a driver who knows how to drive in winter conditions, Lassa Snoways 4 is quite enough for you. If we were to consider 3 tires in the form of Bridgestone Blizzak LM-005 / Dunlop Winter Sport 5/GoodYear UltraGrip Performance+, I would place them somewhere between them in a certain ratio for all conditions. In other words, it is not bad enough to be at the bottom of these, except for road noise, it is not in a position to be the best among them, so it is close to the ideals, neither at the bottom nor at the top. 2nd in some subjects and 3rd in some subjects.
