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.

Good aquaplaning properties, quiet, low price.
Understeer in both wet and dry. Long dry braking distances. Increased wear.

Questions and Answers for the Roadstone CP661 Classe Premiere

Wandering if these tires are suitable for light snow conditions - CP661?

The Nexen / Roadstone CP661 is a summer tire, and as such will have extremely limited snow performance. It is advised to switch to a dedicated winter tire, or a winter-bias all season tire if you expect snow running.

Given 44% while driving a Mazda 6 (215/50 R17) on mostly motorways for 30 spirited miles
The tires were decent initial 10,000 miles after which the wet grip deteriorated drastically, the tire tread block corners started to chip. Even smooth wear not present on the tread.
structure of tire is decent after 3 years of usage.

Bought these tires at Goodhope Tires in Cape Town after they recommended but i regret buying them. They are the hardest wheels and very noisy. They are ideal for construction bakkies where comfort is not an issue. The only advantage is that you cant just wear out this tire, its just impossible so thats a plus. But would not recommend anyone buying for a sedan

Given 81% while driving a Renault Clio 1.4 16v (185/60 R15 H) on a combination of roads for 10,000 average miles
I often spend too much time researching my new purchases and analysing their worth, but I found these by accident!
bought a second hand clio and these were on the front, that was last summer and they weren't new. Drove it over the warm, then wet and somewhat cold winter we have just had and have no complaints! I drive so dual carriageway some town/CITY and some often bad country roads. I have found them very good grip wise, not loud enough to be anything to write about, and have yet to get them to wheelspin when I tried quite hard! Car had a fault with tc light so we were testing to see if it was on or off but after a short drive, no wheelspin could be done and tc working well. On my car they have been amazing and good value, tried many other well known brands and have bought my second set of these as they did so well! They are also called nexen with the same CP661 I have heard. Just named in Europe differently... to uk I think..

The Roadstone CP661 Classe Premiere appears to be a direct copy of Nexen CP661 Classe Premiere tires, with the same name and identical tread pattern (just the manufacturer's name has been altered). The Nexen tire gets quite positive reviews (including my own good experience) http://www.tirereviews.co.uk/Tire/Nexen/CP661.htm

The Roadstone version is reportedly not so good, so check carefully before buying.

Given 66% while driving a Mazda MPV LWII 100kw 2.0 DI (210/60 R16 T) on a combination of roads for 18,000 average miles
I got them on the car, so I can't tell how much they had on it..on dry fairly OK for a budget tire, but in wet conditions they would slide my rear end with ease. I guess these budget type tires are only as good as maybe 2 seasons, then they turn into plastic with bad grip whatsoever.

For the price can't expect more, but not bad. My only concern is under wet conditions , have to be triple careful and no speeding at all. For daily driving and still less than 1/3 of wear use very durable. If I would by this tire again yes, is I recomend the tire yes, but NO over speed or cornerig under wet conditions.

I had these on the front axle of my car when I bought it. I'd consider them dangerous. On the front axle, the car wouldn't turn in at all in the wet. I swapped them to the rear axle and got oversteer (from a front wheel drive car!). After 5,000 miles, with no sign of them wearing out, and with continued issues with tire pressue dropping, I had them replaced with Uniroyal Rain Expert tires, to match the other two fitted to the car and things are much better.

These tires fall into the category of 'budget' by all means; however, they're one of the best budget brands I have used. They are not very good on wet roads and has the tendency to warp out of shape or bulge. On the bright side, for a typical daily driver who doesn't intend to push to ridiculous speeds, it is quite workable. I am currently using Bridgestone Potenza tires at the moment which feels light years better, but if I have to purchase another set of budget tires, this would be the choice.
