Did any one else pick up on the fact the Emira has bespoke tyres, they may be 20” all round , yes the fronts will be a different size but the fronts have a different case structure to act like a 19” I started the Video at this discussion

like spark plugs on the supercharged  V6 they will be Lotus only.

That was also true of the Evora NA at launch and the S when it came out, they were Lotus-spec Pirellis but I think that was down to compound not structure.

They were a Mercedes fitment, MO(1) on the front and MO on the rear if I remember right.

I was surprised to see that the stock tyre will be a Goodyear Eagle F1 (the performance pack will have Michelin Pilot Cup 2s).

I wonder why they didn't go with PS4S (especially in the fancy M3-only spec)? @rallyesax, are you allowed to comment?

Probably commercial agreements. That's not my part of the business but before working on the Homologation process, Tyre manufacturers are challenged on : Will you be able to reach the targets technicaly and what price per Tyre it's gonna be? Both of this factor are equally important.

That's what I thought when I heard it was Goodyear.

Has anyone here used that tire?  Cannot of think of the last car I had with Goodyear tires of any form. 🤔

If the car is not from the UK or Italy; it's not worth talking about.

If you watch one of the interviews with Gav he says he held out for 20” wheels and Lotus-specific tyres.  So I think it was primarily design-led.

You might remember Lotus switched to Pirellis fairly late in the Evora development because they couldn’t get the handling they wanted with their original tyre choice.

The Evora was initially Yokohama's and I believe delays and road noise where the main reasons they went with Pirelli in the end.

Are Cup 2 tyres track focused and great on a dry road but pretty dodgy in wet road conditions?

Just thinking ahead.

If it has an engine, I am there to thrash it.

Not a big fan of huge wheels with stupid low profile. I prefered running 18” on my Evora compared to the stock 19/20”. So, I hope that the promissed GT4 car means that there also will be a sensible set of wheels available. Just like the Evora.

If you choose the 19/20 rims on the Evora you got Pirelli corsa tires in a "LS" specification. Liked them on my car but after some years a hassle to get them over here. Now changed to Mich ps 4s.

So IF Lotus create another "LS"-spec it would be nice if they care for LONG TERM availibility also or care for development / recommendation for another tire (and if someone is saying "just change to cup 2 like Lotus did with the 410/ 430 .....cup 2 are not available as 275 20, in Germany you won´t pass MOT if you change to 285 20....)

I thought we already knew there will be LS Goodyear tyres available or is that a different thing altogether?

The point is about long term supply of the LS-spec Goodyears and Lotus-recommended alternatives if the Goodyears become hard to source for the Emira.

The LS-spec Pirelli tyres on the Evora became expensive then difficult to find, with a lot of owners deciding to switch to Yokos or Michelins.  IIRC the Yokos became the standard tyre on the 4xx Evoras and hence people also used them on S1s, but Lotus as far as I know never recommended alternatives to the original tyres.  With tyres being so critical to the handling (with Gav Kershaw holding out for a Lotus-specific Emira tyre) it's odd Lotus don't give some guidance on alternatives when the originals are unavailable.

The Evora S1 was fitted with Merc spec P-Zeros (M0 on the front and M01 on the rear) and then the 4xx cars with Michelins. Not seen too many Evora's on Yokohamas (apart from they being the recommended winter tyre) although that was the tyre of choice through a lot of the car's development. I believe drive-by noise was their death-knell in the 'Eagle' era of the car. 

I did talk to Gavan about the tyres at Goodwood and will try to get some formal reason for the decision from him next week, and how they'll manage it if the bespoke Goodyear becomes NLA.

Thanks Bibs.  My mind clearly playing tricks, I though the 4xx were on Yokos.  And yes Lotus selected Merc spec versions of the P-Zeros but nevertheless they became increasingly pricey and hard to find.  Thoughts from Hethel would be handy :thumbup:

If the Emira shifts tens of thousands of cars globally almost every year then I would like to think that the manufacturers keep them well stocked.   This low profile bit is a worry as Lotus are saying that this spec was designed for the car, so any later deviation from this will be detrimental to the car's handling balance. 

That is how it seems to me anyway.  Just thinking ahead and possible difficulties.

If it has an engine, I am there to thrash it.

@Bibs Did you get some more information from Gavan? 🙂
