Evora S 19/20 Tyres

[Bravo73]

Are they PS4 or PS4S?

[mik]

I had this issue a while back and went MPSS on the rear, with a plan to switch both ends to MP4S at the next change.

PS4S or MPSS with MPSS already on the front.

Plus has everyone found the 285's to be ok?

[Bravo73]

I’d go for the PS4S then (and ‘upgrade’ the fronts when required). 

[blueg33]

Does mixing the tyre specs impact on the handling?  I did that one with the Ginetta and it went from great handling to a scary snap oversteer nightmare.

Obviously the Evora isn't as light, but the power to weight ratio is similar

[Bravo73]

Only on the absolute limit. And the PSS and PS4S will be so close in performance that you will probably struggle to tell the difference (unless you are @rallyesax). 

[rallyesax]

On the dry as Bravo said, if you're below the limit, you wont feel the impact unless you are really sensitive and apart from going from old to a new tire. At the limit, with PS4S at the rear, you will slightly increase the oversteer tendancy. The impact at the limit will be bigger on the wet as contact compound is N°1 for this performance. I didn't test this mix on the wet tho. But balance will be impacted for sure, maybe more or less progressive and/or greater oversteer or understeer tendancy. 

[Bravo73]

To @blueg33, if front/rear balance is a real concern, I suggest that you buy a full set of PS4S. Then sell the old MPSS fronts on eBay.

Won’t it be the other way around? With newer, grippier PS4S at the rear, won’t there be comparatively less grip at the front (so the car will tend towards understeer)?

[rallyesax]

@Bravo73. If the PSS are more than 2 years old in front, you are right, it will lower this difference. But if it's not that old the PSS will keep more stiffness and bite a bit more the dry asphalt than PS4S resulting in OS tendancy 

[blueg33]

Fronts are 14 months old.

 

I think I will go for MPSS and change them all next time to MP4S.

Are there any issues with 285's on the rear?  1% speedo change doesn't worry me, wheel arch clearance and geo does worry me.

When I change my tyres, I'll be going with MPSS in BMW(*) spec. I understand that were tested in Norfolk on the car a while back and had 'very good results'.

No problems with 285 here. I've run mpss and the cup 2's.

No problems here either. I’ve always had the ‘400 sized’ tyres on my S.

I knew for the Cup 2 in BMW Spec as it is homologated like this on 1 axle of the 410. But I didn't know they liked the PSS in BMW Spec.

Why was it not kept for the final Homologation instead of the RT model... Maybe price or sourcing issues ?

[Gothmog]

I have MPSS on the front and PS4S on the rear in original sizes.

No issues, a rather more convincing combination than the MPSS/Corsa combo I had for a few months

Hahaha I guess yes ?

[jerzybondov]

Bringing this old thread back from the dead to ask a related question:

Which wheel is the speed sensor on for the Evora? On my 911 it’s at the front, so going up a tyre size on the back doesn’t affect your speedo, only the gearing by that 1-2%.

Anyone know if this is the same for the Evora?

[Bibs]

Part 7 is listed as 'Wheel Speed Sensor' so there's one on each wheel...

[Troy5925]

My front corsa tyres have plenty of tread left but are looking old and are starting getting air line cracks between the treads

(Corsas on rear also and not due to be changed for a while yet)

 

For a evora S what is now the best tyre choice now that it's 2023

 

Also my tpms works fine do I replace them or just get new batteries fitted?

Batteries in TPMS sensors are not serviceable items, although have seen a video of someone doing it. Have to drill out the sealant and re-seal later. The sensors for the NA and S are quite cheap and are available as aftermarket and there are other cheaper universal sensors that can be programmed. Think there was a guy offering to program them somewhere on here.

Whichever the most recent version of the Michelin Pilot Sport tyre is. It was the PS4S until recently but I think that the PS5S is coming out soon. 

(However, I wouldn't bother with the non-S version of either tyre; ie the PS4 or PS5. These are more aimed at hot hatches etc)

[TdM]

You generally can't go wrong with PS4S. I've heard good things about Bridgestone Potenza and Eagle F1s as well at the moment.

 

I've had all the above in the past on various cars, I've always found Michelin to be consistently good no matter which year or car, they work well in every condition AND last a long time surprisingly. I've found Eagle F1 to be better some years than others (especially in the wet) and wore out quite quickly (whether that's an issue is down to preference to some extent!). Potenza's I did not like when I had them on a car previously, they weren't very predictable, but it may have been the compound that year. I would read reviews here which are always good:

Michelin are always a fab tyre. Probably avoid CUP 2 for road use, you can't possibly go fast enough on the road to notice the increased grip. In the cold, you'll notice the lack of grip with CUP2. 

I run an all-season tyre on my NA, the handling of all Evora is so wonderful that I don't notice the compromise, though clearly they have less grip on sharp turn-in and a small loss of feedback. I wouldn't fit these if it was my only Lotus but I have Elise with Yokohama that give me the joy in that department.

I had Eagle F1 on Exige, they were fab.

PS5S still some time away - but doesn’t matter, PS4S still win all the tests!

[Phaeton91]

I second PS4S.  When my PSS expire that’s what I’ll be going for.  Had them on previous cars and I can’t fault them.
