I've only had my MINI for 3 weeks and I was very uncomfortable with the runflat tires. It gives a very harsh ride and noisy as well. I swapped out my tires with the Firestone Firehawk GTA 02 tires and must say that it made an incredible difference. The ride is super smooth and ultra quite now. The non runflats was money well spent. The interior of the car does not take a beating anymore. It's nice and quiet.
Now it's truly happy motoring.
