Replacing tyres on X3 M40i (20")
Greetings all!
I am an absolute newbie to this community and to the world of tyres for the X3. My current set of Pirelli P Zero (standard for the 20" wheels, 275/40 W106 at the back and 245/45 W103 at the front) are at the end of their life with 3mm thread left, so I have to start thinking about replacement. They will last about 24k miles - not sure if this is good or bad - my driving is normally quite calm. Any good suggestions for the UK? I am considering both RFT and non-RFT options as I found the ride to be quite rough with existing tyres. I looked at repeating Pirellis or going over to Michelin (either Latitude Sport 3 or Pilot Sport 4). I would prefer not to deviate from the manufacturer recommended sizes (front and back), and for TPMS to work as intended. Open to suggestions on RFT vs non-RFT as well as brand preference with reasons. Many thanks, Anton |

Hi Anton, I have 20" on my M40i, I also have adaptive suspension. I have non-RFT P Zero which I find to be excellent in terms of ride and road noise. I know some here will say RFT are so much safer...my take is that in the UK we don't drive into deserts where a flat can be a death sentence so I'll manage with a compressor and goop.
I've been wondering whether to go for Michelin PS/4 but in my case I don't swap to winter tyres and I worry that the softer Michelins will be damaged on the rare occasions I drive in the cold...in general our winters are not cold enough for me to need winters. If it's super cold I don't need to drive. On the one occaision I drove on snow last winter the P Zeros were really good for a summer tyre. I don't know how Michelins would be - might they crack? Are the Michelin warnings just the company being super conservative or is the compound so soft it is more vulnerable than most? I could go all season but from what I read they may not be as quiet as my non-RFT P Zero.... That's where I'm up to with my thinking so far.

if you have a mild driving style and want to get the most out of your tires, why not look to an all season with a higher tread wear rating like the Continental ExtremeContact DWS 06 Plus? Non runflats are reasonably priced and will last much longer than a pzero or even the PS4S

The very next day after picking up my X3 m40i with 20" wheels, I swapped out the run flats with all season Continental XtremeContact DW06 and also retro-fitted space saving spare in the well under the trunk floor.

Thank you all - based on what's available locally, I'm tied between Latitude Sport 3 and Pilot Sport 4 SUV - any reasons to go for the one or the other? Or are they the same?

Mine came with the Latitude Sport 3 runflats from the factory. I've found them to be quiet, comfortable, and even worked well in the snow last winter. When the time comes I would absolutely replace with the same.

But, not sure if it's really an issue. You just hear horror "rumours" that may cause some warranty issues if BMW consider problem down to non BMW star rated tyres. |

Latitude Sport 3 RFTs come in BMW Homologation version (star rated I assume). Non-RFT Latitudes or PS4 SUV are not BMW OEM'd - are any non-RFT tyres marked nowadays for BMW? Don't think this would be an issue though - I've checked with my dealership (Sytner) and they were ok with RFT or non-RFT Latitudes.

My non-RFT P Zeroes are star rated and are original to the car. My car therefore came with a mobility kit.

The UK in my opinion has very limited tyre choices for the X3 M40i, especially when it comes to all season tyres, which I think would be ideal for many UK regions.
21 inch is the worse and limited choices(if any) for 20 inch and a staggered 19 inch set-up as well. My vote would go to Michelin tyres, I don't think you can go wrong with either of the ones mentioned Last edited by FMIB; 05-23-2021 at 01:28 AM.. |

I will be replacing probably with Michelin DWS. Will be getting rid of the RFTs for sure.

If they come back, I may consider them as ran Vredstein Wintrac Extremes on other cars and they were great! |

What is the consensus on having the Spare? Do those with RFT's generally go without the Spare Tire/Tyre option, and those non-RFT's take the Spare option? Or do most take the Spare option either way?
I can see an issue switching to non-RFT's down the road only to find that you do not have the ability to carry a Spare. |
