The Tire Reviews Score is the most comprehensive tire 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 tire 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 Evergreen EW66 receives poor ratings on all three surfaces, with wet road performance being the main factor in the overall downgrade, plus satisfactory environmental performance due to low predicted mileage for a poor overall judgment. On dry roads, it shows poor responsiveness and steering feedback with very imprecise handling requiring constant corrections, oversteering tendencies during dynamic maneuvers with adequate limit behavior, and only satisfactory braking distances. On wet surfaces, it receives poor ratings overall with very early under/oversteering tendencies and poor force combination compared to other test products, plus very low grip and limit performance, with only adequate braking and lateral aquaplaning but satisfactory longitudinal aquaplaning. In winter conditions, it also receives poor ratings due to poor ice braking performance, despite good snow performance with good braking, traction, and handling that combines forces well with safe, precise control and good limits. This Chinese-manufactured tire receives satisfactory environmental ratings with satisfactory predicted mileage and weight, but good tire wear and fuel consumption.

Is this tire suitable for a 2016 Chrysler Town and Country 225/65 R17 ?

As long as the tire is the correct size and load rating then the tire is suitable, however as with many budget tires, they don't perform as well as premium or mid range options so research your choice carefully.

I installed 19 inch and tight profile but its amazing. Best one Michelin alpine 5 second one this tire. I did not stack anywhere and i did not get any problem. Just one thing should be better ice performance. Its not bad but should be better

Wears out very fast, mediocre grip. You get what you pay for. I've had this tire for almost a year now and it's already beginning to wear out.

Chinese-made tires. I regret wholeheartedly after buying this set of tires. It performs quite badly in the snow. I might've gotten on a dud, but my experience has been downright horrible so far. NEVER cheap out on tires

DOT 1812. On dry conditions tires are good but on wet conditions cornering is bad after second year, very bad after third year, cannot trust them over 25mph anymore. Never used on summer season.

Did very well on deep snow and slush. Not worse than my previous Bridgestone WS70 by much if you consider the Bridgestone cost almost double the price of the Evergreen.
Very quiet and comfort on highway surprisingly. Feel confident even with my RWD set up, will definitely give it a shot again once my current set used up.
