All Im saying is that Im running a 255/275 set up now with Michelin PSS's and I couldn't be happier with my set up. I notice a lot more grip accelerating on a corner, in the canyons and I feel a little more stable on the highway. Maybe its psychological, but hey its a good psych feeling

Are you running with spacers? If so, which sizes?

I'm running the same setup and I think it's perfect. Great grip, feedback, quietness, tread life. There's no better street tire that I know of.

I can't answer for him but I was not running spacers on my ZCP with the 255/275 PSS combo. No issues at all

Hi I had read this thread. My question was specifically about feel and driveability bit also weather the e92 sized PSS on 359s might be too stretched and wear too quickly or have less good behaviour than the f8x sized tyres on the wheels of the same size.

Thoughts.

I also posted here but since deleted as this thread seemed more specific... http://www.m3post.com/forums/showthread.php?t=997855

Nah, not too stretched. Consider how your E92 felt with the stock PS2's then amplify the grip by a bit. The PSS tires should also last you longer and provide better grip in wet situations - as I'm sure you're accustomed to in the UK.

Hi. I realise pss is a grippier tyre thanks. So my mind is made up there.

I mean there's more two options. 1) with the f8x sizes that for that car are 'correct' size for that zcp width of wheel and so less stretched. 2). e9x sizes where i wonder if the softer tread compound on the shoulders might mean too much wear when stretched onto zcp wheels.

I don't want to lose any feel so like others here I think the question is also about wherever the relative side wall stiffness of PSS vs ps2 and whether the stretch of oe tyres on zcp was just because they hadn't gotten around to getting Michelin to make the tyre for the .5" wider wheel.

I promise it's not that much of a stretch on the ZCP wheel if you stick to OEM E9X sizing.

Stepping up in width isn't a problem as long as you're not running really aggressive spacers on your ZCP wheels. I have 12mm spacers on all four corners and it's really tight, but no rubbing so far.

Tx. What's the sidewall support like on the wider tyre? Don't want to lose any bite. I've read like twenty threads on this exact question and folks seem happy, but no one seems to have experience of both the stretched e9x zcp OEM (which I have) and the wider and less stretched f8x on the same e9x zcp wheel. The one or two that have were discussing straight line grip or more interested if their spacers will cause rubbing (I have none)

I shouldn't procrastinate but 4 x tyres is a lot of coin in one go to them feel I should've stuck with the OEM sizes.

I thought the stock sizes were far more stretched on the ZCP wheels since they are wider. The 255/275 look like they fit the wheel correctly. The tires guys that did the swap for me also commented that the 246/265 were stretched tight and they were more of a challenge to mount.

From a sidewall standpoint, I don't think it will impact handling too much. You do have a much greater contact patch due to the smaller grooves and that will account more for lateral grip.

Guys who went 255/275: Would you say the larger fronts made the steering feel a tad heavier at all, or not?
I like the idea of better grip and better look, but only driving street and nervous about loosing direct/nimble feel going up in width.

Thanks

Whatever you choose its worth having a look at lovetyres.com...they do very good prices for tyres delivered - I take mine to a local alloy wheel dealer/fitter as they know how to fit tyres without scraping up your alloys.
Also you need to look for the version with the correct load rating.

Morning SFP, regarding the load rating; I would have thought all (at least Michelin) have proper rating at these sizes (whatever it is, 94/100?).

Hi Nik
It seems like there are a couple versions in some sizes of PSS (at least in the UK)
In 255/35/19 you can get a 96XL and a 92Y*
In 275/35/19 you can get a 100Y* and a 96Y
Also
In 245/35/19 you can get a 93XL and an 89
In 265/35/19 you can only get 98XL but three different homologations (Standard, Porsche NO and Merc MO)
If you order online you just have to be careful to choose the right one (In 255/275 you want the one with the BMW * I would have thought).

[Helmsman]

Thanks Senor, and we have 93/98XL standard right?

Yeah I think so.
I have to say - against popular opinion it seems - that I 'm not altogether in favour of moving to a wider front tyre (unless there are unique requirements).
What has been gradually eroded by the move to ever wider front tyres is the feel you get from the steering wheel.
For instance early 911s with thinner tyres with no power assistance gave such a wonderful sense of connection to the road surface that modern cars can't come close to.
The M3 already has quite dull feel to the steering, ever wider tyres are likely to make that worse. Do the ZCP wheels really a wider tyre?

[Helmsman]

Yes, this is what I am worried about. Piles of folks going up in size and are happy. On top it seem quite common people are equally happy with adding spacers.
As not a strong believer in spacers/changing geometri myself, I'd appreciate some input on the actual feel when increasing tire width only.

Cheers

I had stepped up to the 255 width front tire before I added the spacers and the car felt wonderful. I'm absolutely happy with the increase in tire size.

LOL I didn't have a choice. BBK in front was too large.

Thanks man, I'll have another think about the options.

Anytime! I haven't heard of one person regret going to 255/275
