Had these fitted after my Pirellis and these lasted longer, around 80k km per set with regular rotation and balancing. These were fitted to an e38 740i which was mainly used for daily long distance travelling. The fuel economy was pretty standard compared to previous Pirellis and Michelin. The tires really proved to be well balanced in both wet and dry conditions, at a fraction of the cost on the Pirellis P6000 I had previously fitted. I will again for these. Was quite impressed with the longevity.

Came with the car, more than half tread depth left so I thought they would be ok for another year or more - WRONG! They wore rapidly even though I constantly checked pressures and I was less than happy with the grip in any conditions but especially the wet. Overall very disappointed.

terrible tires. Absolutely gutted. Side wall must be made of cardboard, as my Porsche is now scary to drive! Lost all confidence in handling, the rear rolls on the rim when you change direction. Very poor. Should have spent the extra 100 odd on Michelin!

Bought this car 2nd hand with these tires fitted all round and dealer agreed to replace the front ones for the same tires which lasted just short of 40,000 miles!! on 'A' class and country roads. And, over the 3 years of life returned an average 69mpg.
'Comfort' and 'Grip' are difficult to measure objectively in this car as it has a firm suspension, drives like a go-kart round corners and roundabouts and, sticks to the road like glue in all but icy conditions.
Would I buy it again? - unfortunately, the KH11 is no longer made...
