E89 Michelin summer tyres

[flybobbie]

I wonder if tyres are built for reviewers (in this internet age). Do any reviewers look at tyres that have 10k miles on them.
I suspect the first 3mm or so of tread does the useful stuff but under that it's the harder support compound that gives longer life but poorer driveability or noise. My cars is starting to feel like it's on rft.

I'm just about to replace all 4 with Goodyear Asy. 5.
I liked the 2's, but had to fit 3's to rear which became quite noisy with wear, never noticed with 2's.
I hope the 5's haven't got less soft rubber that wears off quick to give a longer life hard tyre. Just living off it's previous hype.

If a tyre is good and popular why keep changing it.

Couple of points if I may…

I found on the Asym 5 the first couple of hundred miles ‘disappointing’…after that they seem to bed in and I would say they are on a par with the Conti Sport 5, maybe not quite as confident in very wet conditions but good still..

That very same internet / normal publications are quick to poo poo poor performance tyres..many people buy the top one not the second one..

So technological innovation aided by marketing is king..

You’ve been spoilt running a plane with an 80 year old engine…

I wonder if way down a list like Toyo would be a better tyre for everyday use, had them on RX7 and MGTF and never thought twice about them in use regards say steering feel..

(80 year old design engine got me home a few times!)

I’m sure for most people most of the time the Toyo would be fine…just not my bag..each to their own…

Sometimes flying with one engine only over water it’s good to have a fully debugged design..

I've had Toyo's a few times on an MR2 Roadster and they were very good. That's a car that relies 100% on decent tyres so there's nowhere to hide, but of course there is very little power to trouble grip. I've had great experiences with Yokohama's too and they rarely seem to get mentioned.

Tyres like Michelin PS4S are "ultra high performance" (or is it "ultra ultra"?), which is a category that no Z4 really falls into. You don't need them on a 35is let alone a 23i but, if it's worth overdoing it on any one part of a car, it would be tyres.

I always stick with the best Michelins that I can get.

The PS4S finish top or in the top 3 at least for all categories in wet/dry braking. I'm on my second set now and will keep with them until something better comes along. I'm sure Continental offer something with similar performance but I wouldn't take the risk unless they are significantly better.

I went for the PS4 on my 335i because they don't offer the PS4S in 17". They are very similar just not as grippy which is a bit annoying since they are only £20 each cheaper than the PS4S on my Z4.

Speak fer yerself.

I remember now, Yokohama on the RX7, think they were highly recommended, 25 years ago!
