Had these tires original on our 2009 Murano. changed them after 55000km. Bought Bridgestone Euporia 890 and will go back to these tires. Only problem with them was that the sides are wearing much quicker then the rest of the tire. Will try with a slightly higher pressure to see if that make some difference.

Original spec tires on my 2008 Terios. They have been used in mixed conditions and perform very well. Very confident at speed and in the wet. Wet grip not so good when you are at about 3mm or less. Snow traction and driving is also good. They last well 25,000 + easily achieved but would recommend not going below 3mm tread depth. I am on my 2nd set now and quite happy with these for this type of car.

Had these as original equipment on a 2007 Nissan x-trail turbo diesel. The tires have just been changed at 46,600 miles. The rears were OK but dry and crazed all over with cracks, the fronts were almost at the legal limit but again, cracks all over. Borrowed pirelli scorpions on my friends spare summer rims but they felt 'wrong' with vague handling from the front in tight corners. I've bought ST20 s again because I like them off road and the surefootedness on the road, even in the rainy uk, (and most sane folk don't tend to push it too much in a 4x4 in the wet) A good solid carcase tire, never a problem off road, not too noisy, not too 'bouncy'

I've done 45,000 km on a Diahatsu Terios 4X4 so far, hassle free, except one sidewall was damaged by a huge thorn in the bush; tire to be replaced.Probably still another 10,000km before changing the set. Slight discomfort/bounciness may well be caused by the short wheelbase of the Terios and not the tires - it's difficult to tell.

No problems over 27000 mixed motoring miles. Slightly noisy on rough concrete roads but excellent grip in all weathers, including snow and ice.
