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 Autogrip P308 Plus Reviews

Given 43% while driving a SEAT Ibiza 1.4TSI ACT (215/40 R17) on mostly town for 4,000 average miles
I didn't put them on by choice, the dealer I bought the car from had them fitted to get the car through the MOT. In the dry they are fine apart for under heavy acceleration where the EPC tends to cut in in 1st and 2nd gear. In the wet, these are honestly the most dangerous tyres I have ever driven on. They lose grip very easily when cornering to the point I've nearly ended up in a ditch several times at low speed and the EPC cuts in during moderate acceleration in 1st, 2nd and 3rd gear.
They are probably OK on a lower powered NA car but definitely not a turbocharged one.

Given 64% while driving a MINI Cooper S (205/45 R17) on a combination of roads for 25,000 spirited miles
For the price of this tyre they are an overall great tyre, they have performed much better than expected. No they aren’t a proper performance tyre but that being said they have enough traction on a 200bhp Mini Cooper s that they don’t get wheel spin in any gear apart from 1st even in the wet. I have pushed them reasonably hard over the last few years and they have still got about 1.5mm of usable tread left but have started to perish around the edges of the tyre. They are very quiet for cruising compared to previous tyres Ive had on the car, and the comfort is decent too.
Would I buy these again, if it wasn’t going on a performance car, then yes I definitely would.

Given 56% while driving a Volvo V50 estate (205/55 R16) on a combination of roads for 24 easy going miles
I have them at the back of my wifes Volvo V50 2.4i for 40 000km. 1.5mm from wear indicator. Not too bad for a budget tire. Sidewall too soft. High speed handling not tje best.

Latest Autogrip P308 Plus Reviews

Given 73% while driving a Suzuki 2008 SX4 1.6 GLX (205/60 R16) on mostly town for 4,000 easy going miles
A pair of these were fitted on the front of my Suzuki when I bought the car 7 months ago. They were dated early 2020 and so had done about 7000 miles at the time. A few weeks ago I got a pair of new tyres and put the Autogrips on the back. They've lasted very well and offer good ride quality- the Kumho pair now on the front are quite a bit harder. On paper they're good value for money, with ratings identical to a Nexen set that were 20% more costly. I don't go for cheap tyres, but you can do a lot worse than these.

Given 66% while driving a BMW 320i (205/55 R16 V) on a combination of roads for 0 easy going miles
I found them on the car a bought. First impression is that the shoulder of this tyre is very soft: even though the pressure is at the max load (as permitted by BMW) the tyre seems flat and it's not a matter of puncture or else, since I check the pressure every month. For this reason, the response of the steering is slow and the handling is not good. It's a good tyre in terms of grip on dry and sufficient on wet, as long as you drive at a decent speed on highway when wet; with a sport driving and at high speed it looses grip and goes on aquaplaning faster than other tyres. Noise is quite good and wear for now seems OK. There are better tyres for same price or less.
