  1. You're welcome ๐Ÿ˜‰ Actually my 400 has only be running on PSS sets for now ๐Ÿ˜„ If I have the chance to test a bunch of PS4S in different OE specs on my car, I'll tell you. But I don't think my company is willing to give me 20 tyres for private investigations ๐Ÿ˜‚ Concerning Michelin tyres sourcing. In the case of high performance tyres, they are only made in France and in the US on a very specific process. Same quality. As somebody mentionned, sizes are made where the biggest market is. Lets say, corvette sizes equivalent will be sold mainly on US soil whereas, AMG C-class sizes maybe in Europe. Etc... For 'normal' tyres, like a lot big companies, it will be manufactured close to their respective markets. We have plants in China for chinese markets, etc... In order to be more reactive and save money on shippings and stocks
  2. Actually this happens when a specific project or car company sometimes do not want to spend too much money on tyre development or that they are lucky enough to find something that works. In those cases, they ask us (tyre makers) to send different specs of the same tyres (in the tyre size they told us) that we have already developped for other OE projects (Porsche, Audi, Bmw, etc...) or they buy some on their own. Then, their test engineers do some internal testings to find out which combination works the best with their chassis, dampers, steering tuning. This is how you can end up with MO1 tires fitted straight out from the factory like @Bruss said or a combination of RT and BMW specs on the Evora 410 in Michelin Cup 2. ๐Ÿ˜‰ What you have to keep in mind, during this internal testings, they probably had some combinations that were awful to drive. Poor in steering response and feedback, mismatch between front and rear (lateral stiffness, delay, grip, etc...), very understeery or oversteery balance. This is something you might experience if you mix on your own afterwards. Maybe you'll have no surprises, or no differences that would be feelable except by a Professional. For Lotus, I think that it was clearly a way to save money because big groups like German car makers, French ones, US, etc... 95% of the time do specific developments with tyre manufacturers for every cars and sizes they are launching. Hopefully things will change with the money brought by Geely ๐Ÿ˜‰ But trust me, today again I was doing some development for a future rwd BMW and even with the same tread compounds, same size, tyreline, etc... the slight changes made to the internals of the different sets I drove where sometimes just day and night ! Some had a very strong rear, oversteering just a bit on hard maneuvers at high Speed, and others, for the same maneuvers, were just going sideway as hell with heavy countersteer ๐Ÿ˜. Some sweaty moments. So yes, the same tyreline of the same sizes, can be very different in compounds, cornering stiffness, internals if they are made for an Audi, BMW, Porsche or a Lotus.

    Evora S Sport Racer (2015)

    Hello and welcome here French pal ๐Ÿ˜‰ Nice Evora you're got there. I'm living in Auvergne but there is also @Babas89 Who's a French Evora owner, and what an Evora ๐Ÿ˜
  4. Thanks for the heads up, I didn't know. We didn't do a specific development there, so it means they took an existing tyre we already had. That's why we didn't see it here. By the way, on Lotus Web site, if you go on the 350 data sheet. It's still written that it comes with Pirellis ๐Ÿ˜‚ Anyway, we are reinforcing our collaboration with Lotus this year. So great things will come out of that I'm sure ๐Ÿ˜Š
  5. I m pretty sure they don't. It is still Pirelli as OE fitment on the 350 I believe. @FK278004 tyres must be replacement tyres already. On this size, is it PS4 or PS4S that you got supplying problems with ?
  6. See my comment above. You are right, it is first gonna be a Porsche and then other car makers OE exclusive fitment. So no replacement market at first. Anyway, I don't think 17" will ever be a size target for cup2R.
  7. Trofeo R is competitor to Cup2 R ๐Ÿ˜‰ but a feedback vs 'normal' Cup2 will still be interesting on your cars.
  8. I'm on vacation right now but should get the information soon about this tyre size. As Exige 350 does not come with cup2 as a fitment, will have to check. Anyway, cup2 will still exist in a near future and plans are not to reduce is size line up. Concerning Cup2 R as mentionned on this topic, It's going to be launch very soon officialy. It is first going to be an OE fitment only with a limited size line up.
  9. I don't know how hard you drive the car. Tires differences will be more and more obvious as you drive on the limit. But PS4S is still a grippy tire and gives confidence with no doubt. Althought it's not a Cup2, so don't mix front and rear. You'll loose initial biting and reaction but still a very good tire on this car.

    Evora GT430

    For the gauge thing. It happened to me on a battery change. So maybe just unplug the + for some minutes and give it a go again.

    Tyre advice

    PS4S do replace PSS. It's the new generation. However, PS4S has had some compromises on 'on the edge' aspects because of some OE asking for it. In that aspect, it is for me slightly less responsive/precise on turn in but bit more progressive over the limit. Don't get me wrong, It's still very high standard sport tyre. But for my personal taste I would stick with PSS on my Evora while I can. Cup2 is an other serious step over them and all the pros/cons were already very well summarized on this thread. Then if wanna wait longer, Cup2 R will be launch soon, but not yet in front/rear Evora fitment.
