Given 10% while driving a Ford Cmax (215/50 R17) on mostly town for 12,000 easy going miles

Fitted 2.5 years ago on Ford CMax. Around 12,000 miles driven since & our trusted garage said they had perished, would fail the MOT & needed replacement.

Not good enough after just relatively low mileage.

Given 83% while driving a Volkswagen Tiuan R Line (255/40 R19) on mostly motorways for 40,000 average miles

I fitted Cooper Zeon's CS8 two years ago doing about 25K kilometers (17K miles) per year. They were replacing a set of Continentals and were selected due to their cheaper price tag. Although cheaper they were great tires. The side walls appear to be a bit softer than the Conti's or other tires I had before, but overall I was really happy from their grip, handling, dry or wet. Fresh rubber appears quieter compared to their end life and surely returned an very good tread life. I replaced them with a set of Goodyear Asymmetric 6. If anyone is interested in Cooper Zeon CS8 please go ahead and buy them. Just a word of advice for drivers leaving in warm-hot climates. Always look after tire pressures. These tires warm up - overheat in long trips and if you overinflate them you could easily eat away the middle part of the tires.

Given 27% while driving a MINI Cooper SD (225/45 R17) on a combination of roads for 8,000 easy going miles

Possibly the the worst tires I have ever had. We put these on both of our mini coopers just over a year ago. The first set on the Copper SD: Within 3 months the 2 front had bulges in the sidewalls (they were however quickly replaced under warranty), 8000 miles on the 2 front now need replacing as the tread is on the legal limit as well as showing signs of being perished, and the rears have perished and also need replacing. Second car Mini Cooper - 12,000 miles on front are illegal, and all 4 are showing signs of being perished. Worse tires we have ever bought and these are not cheap budget tires. I normally get 15,000-22,000 out of a set of tires. Will never buy again and are currently awaiting a response from Goodyear (who own them. Given the poor mileage, bulging and short life - I'd class these as budget tires and suggest they are well overpriced.

Given 47% while driving a BMW 320i (205/55 R16) on mostly country roads for 5,000 spirited miles

I had this tire on my BMW E46 320Ci. In the dry it was gripping alright considering its price, in the wet tho the car lost its rear even in not very demanding situations. Wet braking wasnt that good too. Best thing about the tire is the sporty looking sidewall

Given 79% while driving a Mazda Mx5 2008 (205/55 R16) on mostly town for 27,000 average miles

After 43k I must say that they hold on pretty good. I think that they could at least last another 20k. Dry and wet grip are still safe but not as good as new. Traction is I think where they have lost the most. Comparing to the Dunlop rt I used to have these are holding on better. I had to change the dunlop after 3 years and 35k. If I had to choose between them I would get the Cooper's

Given 47% while driving a Ford S Max (225/50 R17 W) on a combination of roads for 10,000 average miles

These tires have managed 10,000 miles on my S-Max and I'm not going to buy them again. The first two thirds of their life seemed fine, but after about 5,000 miles road noise started to increase noticeably and shortly after that wet grip started to worsen. They wore from 3mm to illegal in the last 750 miles. The innovative wear blocks on the shoulders still showed 50% when the tread across the tire was below the legal limit, so do not buy them for their supposedly innovative features. The Cooper Zeon CS8 is most definite not worth the money.

Given 90% while driving a Volvo V70 2.0D (225/45 R17 W) on a combination of roads for 1,000 average miles

I've just fitted a front pair to replace Michelin Primacy 3 that were down to about 2mm, giving a noticeably long stopping distance. I thought a lot about whether to stick with Michelins due to advice from mechanics and a bit of brand snobbery. These were 40 quid less per tire though and had good reviews so went for it.

They went on just as the temperature was dropping to single figures, so worried if I should've actually put on winter tires. No need - these are excellent. They give a confident, grippy feel in both wet and dry conditions and a comfortable ride.
I'm used to Michelin, Continental and Goodyear and these are definitely up there with all of those.

I can't comment on wear as they're only a month old. So far, so good though.

Given 87% while driving a Mercedes Benz SLK 230 (225/50 R16) on mostly town for 1,500 spirited miles

I have these fitted to two SLK's having grown to like them on one first.
To be honest, they are not pretty, looking somewhat agricultural with tread rolling up the sidewalls a bit too much. But then that's there to aid the wet handing thing I guess so a small price to pay as in such conditions they are brilliant.
The SLK's are not a car that feeds tire feel back to the driver much. But, as that means you have to have some faith in the tire, by leaving it to do its thing without letting you know much about it, I've found these have given me that confidence quickly. In the wet there's little difference in the sensation of sure footedness, and far fewer flashes from the traction control indicator when pulling away firmly than previous tires.
We like them, plus the free replacement accidental damage thing is something we've used a couple of times on other cars which is a real plus to have from Cooper Tires.

Given 81% while driving a Mazda Mazda Miata (205/55 R16 V) on mostly town for 2,000 average miles

I can only compare this tire with the previous I had. I actualy changed tire profile going from 205/50/16 to 205/55/16 mainly for economy reasons and because I wanted a bit more ground clearence. My previous tires were the Dunlop RT. The good stuff: even though of a higher profile the steering response is much much better than the Dunlop. It seems to be a bit more economical. Not noisy. Wet grip and braking is sufficiently good. Although I have them on for just 2000miles they seem to have good wear rate(no wear at all but just city driving). The bad: these are not comfortable tires and not as progressive at the limit. Dry grip is not as good but good.

Given 94% while driving a Citroën C2 VTS (195/45 R16 V) on mostly motorways for 600 easy going miles

Hello from Bulgaria!
I pleased to review my 4 new tires by Coopertires. I put them 5 days ago and roll them over 1000km. First thing I felt was the real grip and feel of the road in wet conditions.
My C2 was very noisy with my previous tires, Zeon CS8 i can say honestly brought back the comfort of this small hothatch. Very quiet, very smooth ride.
The only bad side I felt was slightly increased fuel consuption, but I blame the good grip on the road.
I suspect these tires won't last 3 or 4 summer seasons, but they are acceptable choice with very reasonable price.
I review them only on dry/wet grip, comfort, road feedback and buy again.
