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.

Latest Tire Test Results
The Bridgestone S23 is a sport tire released the year before the test that demonstrates a small time deficit on the track but a significant advantage on the wet handling course compared to its hypersport counterpart. Its strongest attributes include crystal-clear feedback at the front, ultra-precise and light-footed turn-in characteristics, and high stability at corner entry. When powering out of corners, it introduces some instability into the rear, and the test BMW began sliding relatively early compared to other tires. However, with gentle throttle application, these slides remain easily controllable. It was one of three tires showing premature wear during the test, but its excellent wet-weather performance—achieving the second-best wet lap time among all sport tires and the fifth-best overall—confirms its impressive qualities in challenging conditions.

Initial Impressions Review
Given 80% while driving a Yamaha MT09 (180/55 R17) on a combination of roads for 3,750 spirited miles
Great all round tire, with very nice feedback front and rear, you really feel the road and what the tire is doing as you are pushing it.
Grip levels really come up after just a couple of corners and never feels like its running out of grip, more like it gently encourages you to keep on exploring its capabilities.

Fantastic under breaking, even in the oh crap moments coming into a corner a bit harder than you intended, it responds to the change in direction and then hugs the corners nicely.

I have got a very respectable 6000km out of the rear which is now completely smooth in the whole middle section and only a little bit of grooves are left on the outsides, lots of scuffing present in the last 500 km most likely from excessively hard riding in very twisty country roads of varied condition. (For those that know River Road from sackville to wiseman ferry , Putty Road and the trip to Middle Mangrove will understand what I mean)

It really loves to be pushed, and you can easily find yourself right down to the pegs gunning it many times faster than the posted speed and these tires keep asking for more, and no signs of fade present. Even at speeds over 200 it feels nice and grippy on the roads.

In the wet it has ample grip when ridden sensibly, and when nice and warm it gives a clear indication as it approaches grip limits in corners before beginning to slide around a bit but is easily manageable with throttle adjustment.

I'm sure if it was ridden in a more ordinary manner it would last considerably longer than the 6000km I have achieved with it, but if you do like to really push it then I think that's a respectable mileage for some very hard riding.

Also of note, it's done about 200km of off-road riding and it was very comfortable and provided decent levels of precision and traction with sensible adjustments to throttle and brakes and felt comfortable enough to blast past adventure riders with more all terrain focused tires without issue.

Given 90% while driving a Aprilia Dorsoduro 750 factory (180/55 R17) on mostly country roads for 9,000 spirited miles
I've already gone though a pair of these tires, they offer excellent grip and feel in any conditions, my only downside is that they'll probably last you one season of riding on the roads. Haven't used them on the track but for road use these are excellent, riding sporty or casual, it does it all.

Also it has an very progressive feel so it doesn't really ''tip in'' that much, which I personally prefer.
