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.

Given 23% while driving a Hyundai H100 (215/55 R16) on mostly town for 22,000 average miles
Absolutely shocking of a tire however it was a company vehicle... wet weather grip is virtually non existent - even in a Hyundai iload van with the traction control system on.

These tires are very noisy and dangerous in wet conditions. In dry conditions not bad the life span is good . I won't be buying these again will use trusted leading brands again . I gave them a try but not very satisfied over all its the noise they create that is the most annoying

Given 43% while driving a Kia Motors Sportage (215/70 R16) on a combination of roads for 17,005 easy going miles
Traction control kicked in almost every time I touched the brakes in wet weather, cornering was done at below 30mph to ensure no drift. Dry weather was better if road surface was very rough.

Since these tires are Mud and Snow rated that makes them an all-season tire, not a summer tire. In general pretty good for a budget range tire. Not my choice since they were on the car when I bought it, when due to change will go for a premium tire.

Very good tire for road holding in both wet and dry, with good stopping power... can't comment on longevity. If u want better expect to pay a great deal more.

Given 65% while driving a Suzuki Grand Vitara, 2.0 diesel (225/65 R17) on a combination of roads for 100 average miles
First week and first 100km with these tires. Seems to be holding up well. The price was less than half of premium ones like Bridgestone and Michelin and the warranty was decent. Wet weather grip was a concern as the reviews highlighted but here in Sri Lanka, it's 365 days summer and warm dry weather and zero ice with only intermittent rain so went for them anyway. Tire noice is very less and very smooth and the same level as the previous Dunlop Grandtreks. Took a large amount of weights to balance though.

bought them from tireleader.ie which have provided false information on their website. Return was not possible due to enormous high costs involved hence mounted them. Driving in wet conditions is actually a risk of your life with these tires, avoid !
