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 Sunny SN600 Reviews

Given 43% while driving a Vauxhall Corsa (185/55 R15) on a combination of roads for 0 average miles
Am still using these tires since my last review. Very very dangerous on the wet roads. In dry they match most other tires.
I would never recommend buying these tires even if they are very cheap, safety comes first. There are plenty of better tires for the price.

Given 39% while driving a Renault Clio II 1.2 16v (185/55 R15 H) on mostly town for 9,500 spirited miles
Bought the Sunny's on a sunny day, otherwise I would have taken them back should it have been raining. Fairly good grip in the dry but they will fall off if your boot is firmly in the carpet. The wet grip is shocking and this is with a car that has under 100HP! I didnt know an agile Clio could be made to oversteer as much as this. The Mrs has completed under 10k miles and they are barely legal now. Had a set of Kleber's on before that did double the amount. The one saving grace is that the tires have always been quiet and they do let you know whats underneath you, just a shame they dont like Tarmac!! Cannot reccomend the Sunny's in a month of Sunday's. If budget is your thing, a Firestone, Matador or Kleber will knock spots off these. Failing that, get some Bridgestones.

An update to my review below. These tires are not marked with a rotational arrow, so I felt safe to swap the front tires over from left to right using them in the opposite direction, as the tire blocks were very rounded after 6,000 miles and the understeer at slow speeds on roundabouts was excessive. I have to say the cornering has been transformed, no problem now going round mini roundabouts even from a standing start, which used to result in huge understeer when turning right !
On the basis these can be swapped over, which will give a decent level of grip over the tires life against a tire marked to rotate in one direction only, its a good budget buy.

I had the misfortune to inherit a car with these tires on. They are acceptable in the dry/summer but that's all. The wet properties of this tire is basically non-existent.

Given 44% while driving a Rover 400 (185/55 R15) on mostly town for 2,000 easy going miles
Had these fitted on the front to pass the MOT. Noise level was noticeable on the motorway. Have had to do two emergency stops and on both occasions have skidded to a halt. Huge amount of brake dust on my alloy wheels from low speed stop and start town driving. Require a sedate approach to cornering.

Given 36% while driving a Rover 25 (185/55 R15) on mostly country roads for 6,000 average miles
I bought the car with three of these tires already fitted.

I collected it on a wet day and nearly left it in a ditch on the way home because of the very poor wet grip of the tires.

Grip on the majority of wet roads is unacceptable when cornering or accelerating, unless a very sedate driving style is adopted and this means having to negotiate roundabouts etc at speeds well below the expectations of other road users.

I would definitely not recommend these tires to anybody: with wet grip performance this bad, I have no confidence in their ability to respond in an emergency manoeuvre.

You pay for what you get. They are pretty good in the dry but not as good as other tires I've experienced. When driving in the wet, you might want to suggest taking a bus instead.

Noisy and dreadful in the wet. I fitted 4 new ones and replaced the front after 10K miles when I lost confidence in the ability to grip in the wet. Replaced with Dunlops...superb.
