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.

Good mileage but would not recommend the 600miles due to the wire showing half way around the tyre, it still held together very well.
Did grip the road very well going through all the gears up to 8000RPM every ride on the flat and around corners in the dry, did some wet weather riding with no slip so will buy again.

Did 3900 miles on mine, on the back of a CB1000r. 1500 miles in one long hit killed the centres and I think I could have got another 500 miles easily had I not done those motorway miles.
Great progressive tyre, you can feel it slowly loose and slowly come back to grip, I'd be surprised if you made it break grip in the dry with less that 180bhp, I've never come close on mine. In the wet it only broke free when riding like an idiot. I would have ordered another, but I need a bit more motorway ability (to get to the decent lanes). Just fitting a BT016 to see if the multi compound works any better.

Only managed to get 1800 miles from the back tyre.
Good tyres. Don't really ride that hard. Not had any issues with Them.
Would have liked them to have lasted a bit longer though.
1800 miles. The guy I bought the bike off managed to get 5400 out of a rear.
Think I may try pilot road 4's next.

not a bad tyre once its warm, you just dont get a good feed back from the tyre that its warm enough to corner. very stable at 170mph, And once you corner its not the best on its limit, but a very good lasting tyre for all around enthusiastic riding, mine lasted me 4000km -

OE tyres supplied with the bike were good .Mostly used for week end blasts. 3 track days. Had them replaced @3900 for the BT016 pro. Lit the rear up on a motorway slip road going up hill at 60- 70 ish Pleased with the tyre but wanted / needed some thing a little sticker for the track.

Hard to fault a tyre that is specifically made to suit a bike with so much power (BT-015 M spec).
Look to your suspension before you knock these tyres.

I think the tyre is ok yes it gives good grip in the dry and ok in the wet. Like has been said before the weak point of this tyre is the tyre wear!! I only got 1600 miles out of my rear tyre.

Brilliant in all aspects of road holding. Excellent high speed handling, even two up. Well able to cope with 190+ bhp. Only week point being the miles covered before having to change it.
Would I use again - defiantly.
