Hey Charlie no i've bought a Rapid Tyre Inflator and Holts Tyreweld and stuck them in the boot. If i do get a puncture hopefully these will get me to the tyre centre.

Think I might get both a spare and tyre weld. Leave the former in the boot (as most of the time it's not full) and when it is, take it out and risk tyre weld only.

I did have a period about 5 years ago, where I had 12 punctures in a year. Been good recently though, but memories of a monthly trip to the tyre dealer live on....

I think I know the answer, but given CC2 are only available for my fronts and CC+ for both front and rear, how silly would it be to have CC2 front and CC+ rear? Or given that they are quite similar, would there be no real issue?

Whilst i wouldn't normally be a fan of mixing tyres, in fact i'm usually quite against it, i think they are so similar in performance that you'd be unlikely to have any problems.

[Riccardog]

If it was me I'd not mix and get CC+ all round. Its not like its a massively old tyre design and its already pretty much the best all season one you can buy. Then again, this comes more from an mildly "ocd" view of keeping things consistent rather than any scientific analysis!

Why are you thinking about CC2s? Is the improvement noticeable and if so, would mixing be a good shout?

[Charlie (Wessex)]

I guess it might be down to this....

EDIT - posed the question on there, and the answer was probably not too much of an issue, except maybe in the snow if the fronts had a lot more grip than the rears as could lead to oversteer.

[Charlie (Wessex)]

If anyone is interested, a few days ago, I wrote off to Michelin about CC2 on the front and CC+ on the rear (given CC2 aren't available in my size) and I got the below reply

That combination would be acceptable since they are at least the same tyre family and they are all 4 season tyres. Just make sure you do not mix CC2 with CC+ on the same axle.

Too late for me as I order CC+ all round

Oversteer you say?

Thanks for asking Michelin and letting us know. I don't suppose they shared anything about releasing CC2 in more sizes in the future?

Do let us know how you get along with the CC+. I had them fitted in Feb on my previous E39 and thought they were great. What are you doing about puncture risk?

Which is, I guess, effectively what you'd be doing if you have xDrive and mix them front and rear.

If using that argument, it'd be even more an issue, given a staggered set up!!

[Charlie (Wessex)]

Well the deed is done and they're on. Maybe placebo, but quieter and more supple than the RFTs (no surprise really), Tyre man sucked in a bit when I said xDrive but then said more an issue with X models.

I felt the F1s were a little skittish of recent, but that might be to do with left front toe being out as well as rear camber. Both sorted now.

1 question..... pressures for non RFTs - would they be the same as RFTs?

I'm running the same pressures on my non-RF PS4S, 36 front 41 rear.

Checked my tread depths yesterday too, after just over 8k miles i have a little over 5mm on the front and a little under 6mm at the rear. Amazing.

[Charlie (Wessex)]

I just go by what the TPMS says - usually about 2.7-2.9 bar depending on temperature (which is 39-42).

Popped in to see my indy specialist (one of those that gives a shit unlike a dealer, and who had a 8 week booking time!) and he also said probably do the same pressure for RFT/non, at least that's what he does with his now non RFTs.

Also asked about non star. He said it "should" be ok!! Different now with xDrive than from a few years back, and he sees all sorts of shit that people have stuck on. So we'll see.

BTW , did you get a spare wheel set?

This is quite a good video that helped alleviate my concerns about using non-star marked tyres.

He doesn't even mention star marking and I doubt very much the brand he fitted (Toyo) make anything that's star marked? Interestingly, though, he does makes reference to the 1% rolling circumference tolerance front to rear but, as has been discussed on the other thread on star marked tyres, BMW themselves no longer appear to be sticking to that with cars like the M440i GC and the latest M240i.

Regardless, with my M340i I think come replacement time I'll just look for the tyres I want - probably CrossClimate 2's or similar - and try to match them to the size of the originals. In the event they're not available in those sizes I'll just play safe and make sure whatever I fit stays within the 1% rolling circumference tolerance. Won't be worrying about whether or not they're star marked though....

Sorry, seemed to have missed this post. They also wrote....

The size 225/40 R19 is available from next day however the 255 we do not even have information if the CrossClimate 2 will be in this size at all or not unfortunately.

Seem absolutely fine at the moment. There is a ford with a hump in the road to stop flooding, and usually when cold (it's always damp) you can spin up the rears pretty easily on summers. The CC seem a lot harder to spin up, so grip wise they're good there. Not quite done 200 miles since they've been on, so taken carefully while they scrub in. Seem quieter and more comfy, but then I suspect much of that might be placebo.

Got tyre weld at the moment, and thinking of getting a space saver and leaving in the boot. Boot isn't usually full, so am sure that it could stay there most the tim.

I just put standard pilot sport 4’s on. Car has never felt better since putting them on.

Thanks for all the responses, it ended up being Pirelli SottoZero 3s . Couldn’t locate a set of Crossclimate + , similar lack of availability for Continental Winter Contacts. I’ve fitted SottoZeros to the last 4 cars so expect them to be great.

So those Pirellis are full winters? Tyre Reviews actually rated the Pirelli All Season tyre quite highly (the Cinturato SF2) and it was second only to the CC2 in their test; however, unlike the Michelin it looks like the Pirelli is available in both 225/40 19 and 255/35 19 so I might consider a set of those when my Pirelli run-flats need replacing.

Having said that Auto Bild's test didn't seem to rate the Pirelli at all and equally they weren't very keen on the CC2 either; the Goodyear 4Seasons G3 was their pick even though Tyre Reviews only placed it 5th out of 9! Seems much depends on the test conditions and how the different aspects of performance are weighted and rated....

My investigations, thinking of a high performance All Season tyre for my 5-series, the Goodyear is up there with the Michelin. Weighing up the different performance aspects, for my typical climate, I've not decided which would be my first choice.

Then this has always been the same when selecting on the key performance requirements. An example for me was the in the time of the Michelin PS2 vs. Goodyear Eagle F1 GS-D3. Both tyres had their strong points, but after driving the PS2 in the wet... not so good. The Goodyear was my choice, (for the Highlands), as it was the best wet weather tyre.

Yes, when choosing tyres I think you need to look at where you're driving and also be honest about how you drive; buying a tyre because a reviewer says how well it performs when pushed in the dry on a track is pretty pointless if you'll never take your car on a track and actually need something that will perform well on the public road in the wet!

In terms of an All Season tyre, as I see it the choice for me looks very restricted if I want to maintain the recommended sizes for my current staggered set-up (so 225/40 19 at the front and 255/35 19 at the rear); the CC2 is available in the right size for the front but not the rear, the Goodyear is available in the right size for the rear but not the front and so it goes on! The Pirelli seems to be one of the few that's available to fit both front and rear although I suppose I could look at moving to an all-square set-up as many seem to do when fitting full winters.

But replacement time is still some way off for me so what's available in terms of sizes and/or models of tyre could have changed by the time I actually need to do something!
