...as opposed winter tyres. Living in the south of England, I tend to put on all seasons (with 3PMSF rating) rather than full winters. On my last car these were the Michelin CrossClimate and they suited well.

As there is no spare, I am going to stick with run flats, and there appears to be a tyre called Michelin CrossClimate Plus + Zero Pressure, which I think is their run flat.

Question though, is there a * marked one, or any other * marked all season run flat out there in 225/40/19 & 255/35/19?

Don't really want to go via a dealer, if they even do them, as presume their prices are astronomical.

Continental do the WinterContact TS860S in a run flat in those sizes but I don't think Michelin do the cross climate zero pressure in those sizes.
And none of them are star marked, the star marked winters aren't staggered.

Mine does not have run flats and is fitted with Bridgstone Turanza tyre which from past experience are good, long lasting tyres..

On my last cars I had I had CrossClimates fitted to the Skoda Superb which was a 4x4 and they were great, good in all weathers including snow so I think I may go down that route when the BMW needs tyres..

The Skoda Rapid I had I had a set of winter tyres and steel wheels as I did 100 miles a day in that, and they are fantastic...

I'm just looking at some all season tyres for Mrs JNW1's Cooper S and I think the CrossClimate 2 has recently superseded the CrossClimate Plus? The latter has been around for a while and, while it's still a decent tyre, I get the impression it had started to fall behind some of the competition (hence presumably the CrossClimate 2 which by the sounds of it is an improvement in pretty much every respect). The other option I'm considering is the Goodyear Vector 4Seasons Gen 3 as they seem to score well in pretty much all the independent reviews I've read.

However, I've no idea whether either are available to fit the standard wheel/tyre sizes on the G21 M340i and I'm also not sure whether they're available as run-flats - Mrs JNW1's Mini is on conventional tyres without a staggered set-up which makes things easier!

Don’t discount the stealers, sometimes they can surprise you on consumables, specialist parts/tyres maybe not so much, but standard tyres mibees

Had CrossClimate+ on the Golf 7.5R Estate - got on perfectly well with them. As I never drove right on the very very ragged edge. nor tracked it, I didn't in all honesty see a lot of difference between them and the set of PS4 that I also had. A little less assured in the corners, but not drastically so, and also a little quieter.

Maybe it would be best to give the dealer a call, as well as my local tyre people. I don't really want to buy a second set of rims so hope there is something out there....

Yes, when the time come to change the tyres on mine I think I'll look at all seasons for that as well. Like you I seldom if ever drive my car to the ragged edge on the public road and have no intention of tracking it either; therefore, I think the dry road performance of a good all season will be fine for me in warm weather with the added bonus it will be much better if we get very cold temperatures and a bit of snow and ice in winter.

In terms of the CrossClimate Plus, I wasn't trying to suggest it's a poor tyre, I was only pointing out it's now a relatively old design which Michelin has recently updated. In the size for Mrs JNW1's Mini the CrossClimate2 is available for pretty much the same price as the CrossClimate Plus and in that scenario I can't see any point opting for the older tyre - obviously that might not hold true for other sizes though.

I don't think there's currently a * marked 3PMSF all season or winter tyre available for a staggered setup.

So it's either spare (non-staggered) rims to go with the tyres or else risk something without the *. Possibly not worth doing that if the car is new-ish, as BMW could use it to wriggle out of warranty claims.

paulockenden has BMW ever wriggled out of warranty claims for non * tyres?

As I understand it the issue with X-Drive is the potential problem caused by a difference in rolling circumference front to rear but, that being the case, isn't one way around it just to fit the same size tyres all round? I realise the standard 19" wheels on the M340i are a slightly different width (8" front, 8.5" rear) but from what I understand tyres that are 235 wide will fit perfectly well on both size rim. Therefore, providing you're not bothered about having either the star mark or run-flats, I think 235/40 CrossClimate 2's would work fine on the M340i?

ETA: On the Michelin website it appears you can get CrossClimate 2's in 225/40 and 255/35 for 19" wheels; therefore, it looks to be me like you're able to retain the standard staggered set-up with these tyres. Not star marked or run-flat but to be honest neither of those things would bother me...

The manual says to only fit * marked tyres, so I assume they would.

[Riccardog]

I've also been researching getting CrossClimates as I was impressed with them on my last BMW. Also, for any EU travel you can use these to cover the legal requirements.

My question is, my car has the staggered 19" wheels from factory. Would there be any issues in fitting a non-staggered 17 or 18" set?

Its a non X-drive model, if that matters.

Not in my handbook it doesn't - it says star marked tyres are recommended but it doesn't say you can't use others that aren't. Therefore, personally I think it would be difficult bordering impossible for BMW to reject a warranty claim purely because non-star marked tyres had been used; however, it's a different matter if incorrect sizes have been fitted, especially on an X-Drive car.

[Charlie (Wessex)]

Popped into my tyre dealer. They're pretty good (unfortunately too good and taken over by ProTyre and got more expensive!).

Asked for staggered, *, RFT - said I doubt they could help. They couldn't but said let them know what BMW said, who I emailed this morning.

They also said that they didn't think CrossClimate came in RFT. I think they do, but whether they are available yet on the market is another question.

I could understand moving to a non-staggered set-up with 18" wheels if you were fitting winter tyres but if you're going to CrossClimates couldn't you just fit the standard staggered sizes on your existing 19" wheels? When I was looking yesterday it appeared Michelin offered a pretty wide range of sizes in the CrossClimate 2 (including for the staggered 19" set-up on my car).

[Blackers]

In January I ended up with two punctures when I hit a pothole in Edinburgh. I was running non run flat winter tyres.

BMW recovered my 330e back to the dealer in Edinburgh who then tried to obtain replacement tyres. They couldn't find any star rated non run flat winter tyres and wouldn't fit like for like (I had Continental winter tyres) so I had to get the car recovered to an independent garage who then fitted two replacement Continentals.

Well, that is a good point!

My initial thought was to get an extra set of 18" wheels as I'm not so keen on the 19" runflats that came with the car. But you're right, if I do that then I might as well consider winter tyres along the CrossClimates. As you say, Michelin seems to have increased its Crosscliamte offering now, before the summer there were fewer sizes when I checked.

As it stands I have the factory 19" which will probably last me 3~4 yrs given my low yearly mileage (~5k p.a.)!

I'd have thought in or around London a good set of All Season tyres (such as CrossClimates) would do you the whole year round - would you really need a set of full winters as well?!

[Trevikins]

Been following this thread with interest as I went through the process of considering all the options with regard to a winter tyres and decided to go with the Cross Climates on an 18” square set up with a spacesaver and jack kit in the boot.

I wanted Cross Climates because I had them on my RWD Lexus IS and they were brilliant over 3 winters, 2 of which included frequent trips to Southern Germany. The Cross Climate 2s are getting good reviews but the noise rating has increased from 69dB to 71dB (I’m not sure how noticeable that will be in a G20).

I went for a dedicated square set up due to the fact Cross Climates are directional and it would allow me to swap fronts with the rear to keep tread wear even, plus my nice 19” staggered summer set could be spared from all that salt and grit over the winter months.

With regard to Cross Climates not being star marked I didn’t see this as an issue.

The CrossClimate 2 is rated at 69dB for the size that fits the Mini (17" wheels) and 71dB for the size that fits my car (19" wheels). However, in both cases the figures are unchanged from those quoted for the equivalent size in the CrossClimate Plus so size for size I'm not sure the latest tyres are any worse in that respect?

Fair point I hadn’t taken into account the size increase on the tyre configurator.

[Edited to add] Just checked again and there is a 2dB difference for 225/45 R18 (my current winter set up), that said I’m still not sure how noticeable that would be in a G20.

Ah, see that now! Looks like the noise ratings for the 18's were the same as the 17's in the CrossClimate Plus range but are now the same as the 19's in the CrossClimate 2.

As you say, I'm not sure that would be noticeable from inside the cabin though; the Pirelli P-Zero run-flats on my car are rated at 70-75 dB but they're certainly not intrusive in terms of road noise inside my G21!
