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 Cooper Discoverer ATR Reviews

Given 73% while driving a Chevrolet Silverado 2500 (275/70 R15) on a combination of roads for 31,000 spirited miles
Bought my Chevy truck with these on fairly new, never seen them before. In awe at how much pounding they took. I was hitting curbs, driving over ugly looking rocks and the tires had no problems. The tires are 6+ years old and I've done 3kkm road trips with no problems. For this alone I am getting another set. Alas I managed to drive straight over a bottle and get a nasty puncture, which while mended makes me think the tires are getting old enough to swap.

Given 98% while driving a Land Rover Freelander 2 (235/65 R17 R) on mostly country roads for 1,000 average miles
recent change of tire -now the cooper rated on the "ogri" scale as a 6 so much better than the original goodyear wrangler m/s scoring only 2.
so far in deep road water no sign of aqua planing with no movement when hitting the large volumes of water in recent days. Normal road use produces noticible LESS road noise despite the much deeper tread -(over 10mm )
So Far extremely pleased, will come back with more info when i've done a load more miles( 1000 miles done in 3 weeks so far)

Given 90% while driving a Mazda Bongo 2.5 TD 4x4 Campervan (205/70 R15 T) on a combination of roads for 1,000 average miles
I was running a set of budget tires on my Mazda Bongo 4x4 Canpervan but wanted something a more robust and less prone to punctures on tracks and fields. After checking out the various leading brands I was looking at well over £120 a corner until I read about the Cooper Discoverer ATR's. I managed to get a set for £77 a corner and haven't regretted my purchase in anyway at all (nice looking too). A few months back I was out in a terrible rain storm on the motorway and they were fantastic. Just this week I was climbing steep snow covered hills that other 4x4's with low profile tires couldn't get up. In the dry they are fine and also not noisy like most people think. A brilliant buy and I would highly recommend these to anyone who wants a safe and versatile set of All Terrain's that are certainly very good on any surface.

Given 90% while driving a Isuzu KB 280 DT 4x4 (245/75 R16) on mostly motorways for 100 average miles
Hi I bought Cooper Discoverer AT tires for my Isuzu KB 280 DT 4x4 a number of years back and think they are fantastic tires. I got over 80 000kms out of them - they handled extremely well on my 4x4 and yes they were not the greatest off road - well as an All Terrain they were very good. Most of my travelling is on road anyway so what do you expect. I currently have Cooper ST's on my van - they are noisier than the ATR, but off road handling is very good. On road is suprisingly ok, but the ATR were tops! I would like to have 2 setsof tires - 1 set of ATR and one set of ST!! :)

Given 76% while driving a Toyota Landcruiser (265/65 R17 R) on a combination of roads for 40 average miles
I have had these for 55,000 kms on a Landcruiser & found them a good all-round tire. Road noise is good for an all terrain tire and they have done about 10% off road time, mostly beach & bush tracks. Play with the tire pressures & I haven't had any chipping etc. This tire gives the versatility that the OEM tires simply don't - and they wear better - the toyota is an AWD all the time and is known to be hard on tire wear and these will last twice as long as the OEM tires. Would recommend again.

Given 86% while driving a Toyota 99 Hilux SR5 4WD (265/70 R15 R) on a combination of roads for 57 average miles
Gday,

I use to have the Bridgestone ATRs which I thought were not that bad until I tried these Cooper ATRs.

On loose off road\tracks there is no tracking of the rear tires no tire punchers. If you get these you dont know what tire pressure you should have when off roading. I always have my tires at 28psi or maybe 24psi when on loose off road tracks and have NEVER had a problem and I'm upto my second set so thats over 100,000kms and no probs.

When driving on road I have 34psi in the tires. Drive for 30min and then chk again. Will buy these again and again and will recommend them to anyone.

Given 46% while driving a Toyota Landcruiser (265/65 R17) on mostly country roads for 20 average miles
as they wear you a tram lining effect in the steering Severe chipping on the edge of the tread when traveling on outback gravel roads or 4wd tracks.
Had 2 tires with cuts through to the steel in tread area. Tire pressures were reduced for gravel roads and speeds were about 80-90 Kilometers/hour.

Excellent tires, smooth and comfortable with surprisingly civilised road manners. These are actually quieter than the stock road tires that came with my Sorento (Kumho KL21's)! Very sure in snow and ice with plenty of 'feel'. I will be buying these again !

Given 81% while driving a Nissan Navara 2.5tdi (255/65 R17 H) on mostly country roads for 19 spirited miles
A very good tire if you do a fairly large amount of snow or off road driving. 19,000 Miles done, with 5mm still left, so would not need to replace them for normal road use for a while yet but the of road edge/ability has gone on them. No real road noise to worry about even though a good off road chunky tire.

Given 89% while driving a Toyota Landcruiser (265/70 R16) on mostly town for 30,000 average miles
I have put these on my Toyota Landcruiser 90 after a lot of research. I also do a lot of off roading in the lake district and so far I am well impressed with them. I was advised by a specialist off roader to put these on as they would cater for all the terrains that I encounter and so far he has been spot on. The pictures on the web do not do them justice, you really need to see them in a garage to appreciate the chunky tread and grooves. If you want All Terrains with good road manners but impressive off road ability then these will be perfect and not a bad price compared to BF Goodrich etc
