Michelin Pilot Super Sport 255/30 R21 93 Y XL, ZR

These tyres are great, however here are a couple of problems... 1: One of the fronts needed a load of weight to get it balanced correctly and its still not 100% correct, I would have rejected it had I known. 2: I bought 4x tyres (staggered rears) and all four have different manufacture dates, I was expecting that all four would be produced in the same month (since I ordered at the same time). I bought in 2015 and one was even a 5014 production date, not pleased at all, I even paid the extra so that they were 2015!!!! (they had others on the site with older dates, I specifically avoided them). Had I known these might have been problems, I would have paid extra and bought them at a proper tyre place as I could have addressed the issues there and then. I could not really complain as they are online sales only, so whats the point.

Simply the best tyres I have had on any car I have owned. I put these on the M5 and the increase in grip that they have offered over the Conti's that came on the car is frankly night and day and well beyond my expectations of what a road tyre was capable of. Not usually one for reviews but felt compelled to do so as they really are that good. I cant comment on longevity as have only had them on a few thousand miles but seem to be wearing well and frankly I don't care if they wear sooner than the previous the increase in grip is well worth it. Living in the UK and on wet roads the M5 did tend to struggle with putting well over 500 BHP to the road, which I thought was fair enough a lot of power there! However, not with these fitted, complete game changer and very impressed.

Best tyres ive ever fitted to a 'Road' car. Loads of grip, and i meen LOADS! Excelent in breaking, acceleration and cornering. I put these through their paces on a trip to the Austian GP earlier in the year which also took in some 'spirited' driving through several Alpine Passes and they were fatastic, i could not reccomend them enough for fast summer driving (Don't know about how they work in the winter yet). My mate also has them on his 3.4 Boxster S and loves them.

1 of the tyres requires a great deal of weight to get it balanced, 3 times I've had it balanced and (at £20 a pop) its still not right. I have no complaints about the tyres per say, only about the supply, all 4 tyres have different manufacture dates and I explicitly ordered 2015 tyres (and paid extra) but I received 2x 2014 tyres, and 2x early (week 1) 2015 tyres. I will use the tyres again no problem but will not use the same supplier.

I have had two sets of these tyres. Neither has lasted more than 12,000 miles (19, 200km) on the front axle. I drive in town and on motorways, so they don't meet abnormal challenges. Since buying the tyres I am reviewing, I have had to change again and have moved away from these tyres. They preform well in other respects but not so well that their appalling economy can be overlooked.
