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.

Top 3 Toyo Open Country MT Reviews

Given 81% while driving a Mercedes Benz ML (275/75 R17) on mostly country roads for 30,000 miles
I've had these on my Merc ml430 for.nearly 30k miles . They are only half worn . The side walls are very strong helps with handling and I've had a slow puncture in one tyre for over a year and it will drive like a run flat with hardly any air in the tyre. Dry grip is excellent, wet grip is good and hydroplaning is non existent even at speeds over 70mph . Decent in the snow . Would definitely buy these again. I'm running Yokohama geolander 003 on another 4x4 when they need replacing I think it will be with toyo mud terrain.

Given 84% while driving a Vauxhall frontera (255/75 R16) on a combination of roads for 2,000 average miles
Fantastic off road tyre, amazing grip in both wet and dry - whether its uphill or downhill.
good traction in gravel, mud, grass, snow - you name it :D

only drawback is that they are quite noisy and the ice grip is not that good

Given 79% while driving a Toyota Landcruiser (225/45 R17) on mostly country roads for 40,000 spirited miles
First, I bought them in LT 275/70R18 size, increased from original 285/60R18 size for 200 series Landcruiser. They are a beast of a tire for offroad, mud, gravel, rocks, anything you throw at it will be OK for it. Sidewalls are very stiff, I had 0 punctures. After around 40 000 miles I'd say they are at little below half life. I piched them on roots, stones, drove them at 1.2 bar over lot of stones and mud, nothing hurt them. They are rotated every 6-10 000 km, whenever I find some time to do that. Pretty noisy on tarmac (luckily sound insulation is great), lots of grip for a mud tire on dry road, although they seem to activate ESP a bit earlier than AT's in slower, sharper corners, but I'd say that is also due to changed tire size. On wet road handling is decent, not like road-tires, but decent. I can drive behind everyone going average speeds and not have problems. Aquaplanning is non-existent for these. They do swallow a lot of fuel, I'd say 1,5-2 liter per 100 km increase... They are very heavy compared to AT's. Due to stiff sidewalls, car will tend to sink in mud, especially heavy car.

Given 27% while driving a Jeep wrangler jk (315/60 R20) on mostly motorways for 0 average miles

Given 74% while driving a Land Rover Discovery 2 (275/70 R18) on a combination of roads for 7,500 spirited miles
Having used BFG KM2s and General Grabber ATs I can confirm these are the best out of the bunch. Very quiet and genuinely brilliant road manners. They are extremely tough and durable, strong sidewalls that take a beating. Mud performance is great too. Only downside is that they wear reasonably quickly but they are a far superior product in pretty much every way I can measure everywhere else.

Given 71% while driving a Toyota Landcruiser (285/75 R16) on mostly town for 6,000 average miles
The best MY tyre on asphalt. Still feels like using normal tyre on highway. But, whenever using on steep hill with clay terrain, the grip is very low compare to other MT tyre.
