Are the Michelin PS4S just the standard tyre or is there a 'LTS' spec branded/approved by Lotus? The 340R has Yoko LTS branded so just checking before messing this up.

rallyesax Posted May 4, 2021 Report Share Posted May 4, 2021 No they are not LTS branded. Even the PSS or PSCup2 that are fitted brand new from the factory for Evora 400 or 410 are not branded. They are not specifically developped for the car but Lotus did test a few combinations to pick up the Front and Rear axle tyres that had the best match with the car. That's why you find a mix of RT and OE spec on the car. If any full development are undergoing or will be done in the future, you'll find Lotus markings 😉 1 1 Quote Link to comment Share on other sites More sharing options...

However, the OEM TPMS might not be too happy with those values (and can’t be adjusted, BTW). Blimey that's low!!! Can I ask why that low? Does it handle better or is it more about comfort? Cheers @rallyesax I've now got MO P Zeros on the front and MO PS4S's on the rear......Am I going to end up in a hedge? Quote Link to comment Share on other sites More sharing options...
rallyesax Posted May 4, 2021 Report Share Posted May 4, 2021 😂 That's a good question, never tried this kind of combo. I don't know what's inside an MO spec Pirelli. It depends of the car it was developed for and was made to match with a specific rear to fulfill a specification of dry Handling, wet Handling, RR,... It's a proper Lottery there 1 Quote Link to comment Share on other sites More sharing options...

That should be 2.0 front, 2.2 rear. (These were the ‘standard’ Evora 400 pressures for the PSS). But, 1.8/2.0 seemed to be working fine today on a brief ‘blast’.

rallyesax Posted May 4, 2021 Report Share Posted May 4, 2021 On dry roads and if your not tracking it, you will be very fine/safe. On track, you could just end up with a very unbalanced car (understeery or oversteery) On the road, it's only on the wet that you might struggle a bit depending of compounds and volumic ratios. The car might be not so grippy on the front or tail happy in the roundabouts more than usual... Or not. Quote Link to comment Share on other sites More sharing options...
Gold FFM TdM Posted May 7, 2021 Gold FFM Report Share Posted May 7, 2021 (edited) I would expect understeer when wet and/or cold with the Pirelli on the front, not much of an issue I would think. Think I'm running 2.2/2.4 F/R on my PS4s at the moment. Mainly because I don't want the TPMS to buzz at me. TPMS triggers at below 2.1 I believe which is annoying.

cdco Posted June 18, 2021 Report Share Posted June 18, 2021 Well bit if a thread resurrection here , just pulled the trigger on a set of PS4S'S in the 18/19 size combo now the're available for the LE from the tyres on the drive lot as they've a 15% discount running and I can watch them do it whilst working from home. Hoping it will feel a little better balanced on my August Donny track day with LOT than it did at Blyton with Corsa/Rosso PZero mix it has on currently ...taking a bit of a flyer though and haven't replaced the tpms sensors as there all behaving.

series_one Posted March 15 Report Share Posted March 15 (edited) I love the difficulty of getting this right 🤪 Which one is the best? PS4S rear 255/35ZR19 (96Y) XL ★ 255/35ZR19 (96Y) XL MO1 255/35ZR19 (96Y) XL 255/35ZR19 (92Y) 255/35R19 96Y XL GOE 255/35R19 96Y XL ★ With the P Zero’s it is MO front MO1 rear PS4S front is only available as plain XL type 225/40ZR18 (92Y) XL After 10 years of P Zero’s I am going to change to PS4S Bibs - would you mind asking Gav or someone else at Lotus, please? I believe XL front and rear was suggested at some point? thanks Edited March 15 by series_one Quote Link to comment Share on other sites More sharing options...
Popular Post KennyN Posted March 16 Popular Post Report Share Posted March 16 GOE Is Genesis recommended (for the 2 people that have bought one!) * Is BMW M Is Mercedes If your manual recommends XL rated tyres then go for the non manufacturer specific XL tyres in the correct size and rating. You will not regret switching from P Zero’s to PS4S. 5 Quote Link to comment Share on other sites More sharing options...

j141 Posted April 1 Report Share Posted April 1 Thanks for all the useful info everyone, I am due a full set on my 410, I currently have Cup 2's all round. It looks like the consensus for fast road is PS4S as the Cups are widow makers in the cold which it is 40-50% of the year and the wear rate is awful My only worry is the car will loose some of its handling if I switch, there must be a reason they spec'd the Cup2's? I am only fast road, no track days, what do people who have switched think? Quote Link to comment Share on other sites More sharing options...
Gold FFM TdM Posted April 1 Gold FFM Report Share Posted April 1 I haven't tried the cups on the Evora but switched in the past on another car. I suspect you will notice a difference somewhat. They are great tyres on the road but they do have a little bit of lateral movement in the wall which introduces a slight delay at the limit to my butt/finger feel. You may also lose a little granular feedback on road surface as they 'slur' across the road surface more. It's when you are just on/past adhesion and you can really get a feel for whether the tarmac is tight grain or wider stones, it's not communicating that as strongly. However, are you going to notice that 99% of the time? Probably not. PS4s are really good all the time all year round. 2 Quote Link to comment Share on other sites More sharing options...

electro_boy Posted April 3 Report Share Posted April 3 If you still want a sporty feeling tyre have a look at the Continental sport contact 7 or the Goodyear eagle f1 super sport. They can’t match the all round road tyre abilities of the Mich PS4S but they have a sharper turn in and more feedback. Lean towards the Conti for road use and towards the Goodyear if you do track days. 1 Quote Link to comment Share on other sites More sharing options...
Gold FFM jep Posted April 3 Gold FFM Report Share Posted April 3 I had Goodyear on the LF1 Exige, which many road only Exige owners seem to opt for over the factory Pirelli. Seemed good to me, though I tend to drive slow in, fast out with regard corners on a public road. Justin 1 Quote Link to comment Share on other sites More sharing options...
Gold FFM TdM Posted April 12 Gold FFM Report Share Posted April 12 I'm also interested in knowing what the Contis and F1s are like on the Evora, I do hear that they are very good in general. One of those things where someone would have to bite the bullet and have a go. Quote Link to comment Share on other sites More sharing options...
Cdm2018 Posted April 12 Report Share Posted April 12 There’s a u tube video from that guy that does a load of tyre reviews the PS5’s were still pretty well tested so I guess in comparison to other premium brands Michelin still a good buy I wonder if PS4S will be discounted as there’s PS5 now available ? I am happy with my mix of PS4 & PS4S 1 Quote Link to comment Share on other sites More sharing options...
Gold FFM TdM Posted April 12 Gold FFM Report Share Posted April 12 PS5 doesn't replace the PS4S. I suspect there will be a PS5S at some point but might be a way away yet. Quote Link to comment Share on other sites More sharing options...

One of those things where someone would have to bite the bullet and have a go. I guess most people either use their car as a daily so the Mich PS4S makes a lot more sense or a Sunday special car so use the Mich Cup2 as spec'd by Lotus. Contis and F1 are middle ground in between them. Also I find Lotus customers tend to stick to OEM spec as Lotus are renowned for their chassis tuning more than others so don't want to ruin the world class handling. If the community want to club together and buy me set of tyres I'll happily test them out on my NA Evora 😉 57 minutes ago, TdM said: PS5 doesn't replace the PS4S.

Popular Post RedViper Posted April 12 Popular Post Report Share Posted April 12 For Evora 400 owners I found this video very interesting. You can get the BMW * marked PS4S in lotus sizes…. If you go 245 on front instead of 235 (which lotus does on the 430 wirh same rim dimension) seems like dream spec for a tyre to me. Let’s face it if it wasn’t for fast Cup2 arent great in wet everyone would use them. These star marked that take the PS4S closer to Cup2 dry performance but still allow car to be use in poorer conditions (more so than Cup 2 anyway) for fast road / track users seems perfect 3 1 Quote Link to comment Share on other sites More sharing options...
electro_boy Posted April 12 Report Share Posted April 12 Thank you @RedViper, I watch a lot of the Tyre Reviews content but have missed that. Very interesting, I may be having a look at BMW spec tyres when I need new ones. Quote Link to comment Share on other sites More sharing options...
