I have posted this over on the X3 forum but some on here may have experience?

I am looking to change my Bridgestones to Pirelli RFT, NRFTs are very hard to get in correct 21" size so these seemed are good choice...Does any one have experience of these? Not necessarily in 21" of course?

Pirelli PZero 245/40 R21 100 Y RUN ON FLAT (PZ4), XL,

I've got PZero's on the 640 and I'm very happy with them.

Hi
Thanks for that, take it they are the same RFTs ?

275/35 20Y (102) Rear and 245/40 20Y (99) Front RFT's

I have them as 21" on my X3. More than happy with them good grip and not too loud. (Although quite pricy compared to the Bridgestone)

My G21 has Pirelli P-Zero run-flats (albeit 19" rather than 21") and thus far I think they're fine - definitely an improvement over the Bridgestone run-flats that came on my F31. Ok, they're probably not as good as a premium conventional tyre from the likes of Michelin, Continental, Goodyear (or Pirelli!) but they're also a long way removed from the ditch finder RFT's BMW were fitting 10 or 15 years ago; come replacement time I might switch to conventional tyres but I'm certainly not thinking I need to bin the existing P-Zero run-flats early to get some....

I got these as standard in 20" when I bought my X3 M40i. Decent tyre.
