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.

Hi guys, would a size of 225/45 R19 have a rim protector on this tyre?

I've spoken to GT Radial and they say that size does have a rim protector :)
June 2, 2024

Does the Active Sport 2 tyre size 255/35/20 97y have the rim protection.

Yes, all UHP GT Radial tyres have rim protection. It's not as big as some of the Bridgestone and Pirelli offerings, but it's there.

Top 3 GT Radial SportActive 2 Reviews

Given 90% while driving a Holden Commodore VE (245/45 R18) on mostly country roads for 1,200 spirited miles
Great value for money sports tyre, with very good grip levels in the dry and wet. Vastly reduced hydroplaning frequency, and has the ability to take sharp corners at much higher speeds compared to lesser brands. Some increased tyre noise compared to more expensive brands. Highly recommended for the price point.

One of the best tyre I ever used. Worth it for money. Especially wet drip and comfort

Comfort and Quiet sporttyre with good feedback. Biggest minus is weak driving distance, ~18tkm and gone.

Initial Impressions Review
Given 74% while driving a Ford Fiesta mk7 (205/40 R17) on for 5,000 miles
Using this tyre on my wife's Ford Fiesta Sport. I have GY Asy5 on my own car. The Asy5 is much better I need to state. Even if the numbers on the reviews showing quite similar results. The GT Radial is a fair option, good value for the money, solid mid-range tyre. It feels a bit hard to me, fast cornering makes understeer and comfort is also behind the Asy5. But not bad overall, better than Nankang AS2+ I had before.
