Always used these tyres, they are on a BMW 330D Saloon 2015 (F30) so quite weighty at the front end, i always lose the runflats on any car straight away just because the ride is too hard, they crack alloys and they’re mega expensive to replace. I find these Rotalla tyres tick all the boxes, they’re quiet, they stick to the road like glue in the wet and dry, i would definitely say i’ve given them enough chances to let go with some fairly spirited driving through bends. I usually get around a year out of them which is about 16,000 miles, i’m more than happy with that as my Bridgestone Run Flats where only ever good for around 12,000 miles. I almost gave Dynamo’s a go this time as they get good reviews but stuck with the Rotalla because Dynamo didn’t have the 225/40/19 i needed for the front.
