Hi i was wondering does anybody know if this is true. Im looking to replace my front 2 tyres which are currently 205/40-18 Dunlop SP Sport 01 DSST Runflats with Non Runflats, but iv been told by my local dealer and a seperate tyre company that these rims can only take a Runflat tyre so therefore i cannot put on a Non Runflat of similar size. Any info back would be greatly appreciated the rims in question are 18x7 R95 spider-spoke (JCW). Thanks in advance.

Load of dump I have heard plenty of times in order for you to buy the more expensive runflat tyres. There is no such thing as a rim only being able to take runflats.
I had aftermarket alloys on my car with 6 month old Goodyear F1's, 215/40 R17. I purchased official JCW R112 alloys and got the tyres swapped over at £20 a corner no problem. Plenty of people on here have official alloys with normal tyres on and enjoy a greatly improved ride.
The only issue you have is you shouldn't mix runflats with non-runflats.

Definitely do not buy runflats, it's BMW policy to recommend them, god knows why. Saying rim can only take runflats is total non-sense.
I can recommend size 215/40 R18. Toyo T1 Sport 215/40 R18 is probably the best tyre in this size. If you'd like lower profile 215/35 R18, then Goodyear Eagle F1 Assymetric. I don't see a good reason for 205/40 R18, but if you insisted on this size, then Michelin Pilot Sport 2 is the best tyre in this size. I spent days reading opinions, tests, reviews and this is what I gathered :-)

I can't believe they are still dishing out this nonsense. You can use non-runflats on OEM wheels. 215/40's are popular as they give a little more sidewall to protect those valuable alloys, they give a little better ride comfort than 205/40's, they look a little better and are usually quite a bit cheaper as it is a more common size. I chose 215/40 Hankook's for their ride comfort and consequently have the same ride comfort as 17's with non-runflats. The ride comfort is streets ahead of runflats in any size.
