R56 Cooper S - Ditching the Runflats on R112s
Discussion
Picked up a MCS (2011) R56 the car came on a brand new set of run flats running R112 rims - the ride quality is borderline dangerous - the car bounces around everywhere! Is this because the tyres are still new or is that a characteristic of the RFTs?
Has anyone changed to normal tyres and if so what did you go for? Would it be a like for like swap in terms of tyre sizes to the non run flats? Thanks

Good timing. I bought a 2010 R56 on Sunday, runflats all round and very worn on the back. Horrific. In the wet yesterday they were plain dangerous (polar opposite to the Rainsports on my last car). Ride quality was horrendous and tramlining all over the place. Earlier today I fitted normal Yokos in 215/45/17 size (Advan Sport v105s - £80 each), what a difference. It's still "firm" but the crashing has completely gone and it's all much more composed (it's never going to be a limo though).Has anyone changed to normal tyres and if so what did you go for?

Thanks the standard tyre size is 205/45/17 so what made you go with 215's? Was this advised or something you tried yourself?
There's plenty of discussion in various forums. For me they offer a small amount of extra rim protection, slightly higher tyre wall (improve comfort, but minimal) and they were about £20 a tyre cheaper. No significant negatives.df76 said:

Cheers - what about insurance - you are now on non standard tyres!?
You'd need to ask your insurance company.Changed our Dunlop RFTs last year for Michelin PS3. Better ride quality, but the Dunlops were definitely not 'dangerous' even though they were down to 2ish mm!

Why? As long as they are the correct loading.
I've heard some are funny about it. I've had no problems ever, but no harm checking..Always worth checking with insurance as they like to worm out of stuff, only if it worries you. The 215/45 is better suited to the R53 or R56 and it certainly helps the few mph discrepancy on the earlier car, changing from rft on mine made a night and day difference, but then I used Federal RSR595's haha, delicate in the wet sometimes, but funny in the dry in comparison. Speedo more accurate, looks better in the arches too.
I hated the mini on run flats. Fine on a perfectly smooth road but BMW forgot that the roads are far from perfect. A slight bump on a bend and you would bounce into the oncoming lane.
I changed my runflats to Avon zv7's. Not to expensive but not budget. It's like night and day and made the mini enjoyable.
That concrete section of the m25 is still a horrible drive in the mini though, it's like driving with a flat tyre.

Has anyone tried the new Bridgstone DriveGuard run flats? They have many benefits over a std RFT, but most important, they have a comfortable ride.

All I can say Is I have an R56 MCS which I now love, however, when I bought it, it had Dunlop runflats which are great grippy tyres but I agree it was deeply upset by bumps mid corner and the car would have tendency to tramline all over the shop. I moved to Rainsport 3's non RFT and the ride and handling is a hell of a lot more "grown up" and enjoyable. We then bought another Mini a clubman which already had rainsport 3s installed so great minds and all that. So I am sure other tyre preferences will work on the mini, but personally the thump crash and sideways hopping of runflats under power was leaving me to question why did they ever fit these???
