5/5Kumho Ecsta HS52Amazing tyre capabilities. I can apply all the power on my diesel Mondeo without the wheels losing grip!
3/5Goodyear Eagle F1 (Asymmetric 2)As for the grip, it's great as I expected, but they do make quite a bit of noise (run flats).
5/5Bridgestone Turanza T005Good traction on these tyres, however, they seem to wear faster than would be expected.
2/5Goodyear Eagle F1 (Asymmetric 2)These tyres are generally underwhelming. They struggle with performance on all cold and slippery surfaces and don't perform well where the tarmac is smooth. They work well enough in wet conditions though. Other BMW drivers are saying the asymmetric 5 is way better than the 2. Runflat tyres are stiffer than normal ones and so are grip wise worse under load. If you drive a BMW and have any knowledge of cars, the majority will suggest ditching the runflats for normal tyres and putting a puncture repair kit in the glovebox. I would advise the same.
5/5Goodyear Eagle F1 (Asymmetric 5)I immediately noted increased traction both in the wet and dry - I feel like I'm behind the wheel of a completely different vehicle.
