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.

Top 3 Nexen Roadian CT8 Reviews

Given 63% while driving a Peugeot Boxer (215/75 R16) on a combination of roads for 20,000 average miles
Cargo tire with great wear and good dry handling. Unfortunately they are terrible in the wet and the wet characteristics get worse every year as the tire ages. Cornering in the wet is especially bad and feels like a 20 year old tire was fitted. Also very sensitive to temperature, as dry grip decreases significantly if the temps are

Given 74% while driving a Citroën Relay (215/70 R15) on a combination of roads for 10,000 easy going miles
Two tires developed bulges after short time of being used, with still plenty of tread left to use.

Given 62% while driving a Peugeot Boxer (225/45 R17) on mostly motorways for 0 average miles
We bought a van with Nexen tires. After one week we had to change first time the front left tire (cause of breaking the steel thread in the tire) The second tire kept for appr. 1 month, and the same situation. Now (after half year) the same condition with the rear left tire. 3 from 4 with normal urban and suburban usage. No overload, no overspeeding. I can’t guess, what happened. Can’t fail anything else, but tires. We’ll try now the Vanhawk. Regarding this I not suggest the Nexen for vans.

Given 44% while driving a Fiat BURSTNER i640 (225/70 R15) on mostly motorways for 8,000 easy going miles
The tire pointed ways on the role of the characteristics (higher index of load and speed than the originals). At 11000 km the rear wheel burst on the highway without justifying cause I have also been noticing for a month that it is going to the right with what I suppose, the rest of the tires go the same way. They do not generate confidence in me and also I think they are not good, I have been noticing for a while that they are weird. They only have 10 months of normal use

Fitted 6 of these to my A Class Motorhome in place of Michelin Agilis which had started to crack and bulge a 4 1/2 yrs old....Really pleased with the quality of the Nexen's….we compared them with the Michelin's on removal and the stronger construction of the Nexens was immediately apparent... the drive very well..

Nexen Roadian CT8 are the tires I bought instead of previous Infinity tires, which were horrible.
CT8 are actually great choice for the price, I will most probably buy them again. Two seasons done perfect with them, I believe around 30.000 km.
