Non OE spec tyres

[Topfox59]

I’m struggling to find a set of front mps4s tyres for my Ftype (255/35/20)
I’ve found a set on Camskil but they are ‘volvo’ spec.
I’ve seen people have fitted MB spec tyres of the same brand and size.
Is this an issue as the Michelins are not a OE spec tyre for Jag anyway.
Tread pattern looks the same
TIA

The volvo Michelins () are two version one an acoustic version. The difference is price ( slightly cheaper) a lower dba value and better (A) wet weather performance.

For normal use on roads it's all rather marginal and doubt you'd ever know. Ultimately the Volvo spec tyre has been changed from standard spec to better show the characteristics sought by that manufacturer. It may be for better wet use vs ultimate handling or to perform better with their suspension, weight, quieter ride, etc. Whatever you can be sure it's not so suitable for an F Type.

Standard spec tyre is a compromise to suit most needs of a high performance Summer tyre.
Personally I'd never fit a tyre developed for a different manufacturer, but happy with the stock tyre, as are many on here

I'd also pay little attention to which brands a manufacturer recommends (Tyres, oils and lubricants, etc.) as that more down to marketing deals than anything else.

I think this video has been posted before but shows how far an aftermaket tyre can be tweaked to meet the needs of a manufacturer, so may help guide you..

Thanks will keep my eye out for the standard mps4s

While you may not need all-season tires in old England, they allow driving year round here in New England.
I swapped my OE P-Zeros for Michelin PS AS 4's last Fall and plan to use them year-round.
IMO they handle better than the P-Zero Summer tires (limit 45 degrees F).
They are a little noisier but not a problem, and they have much better wear rating while meeting all other performance specs.
Regarding the OE Pirellis, my (new, 2021) car came fitted with P-Zeros marked AMS (Aston Martin).
Apparently there is a J (Jaguar) version but JLR saw fit to go with the AMS version.

Different models have different specs.
Mine for example is J front and AMS rear.

I'm let to find the difference between J and AMS in terms of structure.

It's probably because the J rated rear tyre is 285 (as fitted to the XKR), not 295.

Maybe look for the new contisport 7’s, they’re getting great reviews and have apparently set new standards for UHP tyres.

It looks like ATS have the generic PS4s back in stock again.

 

[Topfox59]

Got a message from Camskill regarding the VOL tyres (MPS4S 255/35/20) spec tyres they have available.
Too be honest the reply left me with more questions than answers

So long as the tyres meet the required specfications for speed, weight, load, etc. you'll be fine. They may not give optimum performance but they'll meet your insurance requirements.

I agree with SCM that provided the spec meets the requirements then it's not an insurance issue.
Michelin warranty seems unlikely that you'd have a claim, but I can see how they would use it to avoid accepting one, but I agree on the other points re handling and wear, as per my earlier post

On the website yes- paid for(£181/corner) and thought great.
£360 all in with fitting/disposal.
10 minutes later the local ATS centre rang to say there’s no stock and they are refunding my money
So back to looking for a set of front tyres!!

Try Black Circles, get them sent to your ATS.

When I used Black Circles I chose ATS to mobile fit my tyres. ATS didn't show up and I eventually found out they didn't think they could fit the tyres in their mobile van. They didn't bother to tell me, of course, that'd be good customer service. I eventually went with Halfords who did a great job mobile fitting for me -even pandered to my whims for centre cap and locking wheel nut alignment!

Tried but none available. Apparently this isn’t an issue just with Michelins. 80% of Carbon Black which makes up the bulk of tyre compound is sourced from
Russia….

OE spec...I know of brand spanking new F Types that P0's marked AMS on them, so kind of blows the belief I had about specific OEM tyres right out the window.

Personally, I have gone with Mich PS4S's, 10mm wider front and back and couldn't be happier. Stick like muck to a blanket!

Well, Astons are just expensive, not quite as good, Jaguars .... :lol:

KInd of strange that AMS tyres are more available than J tyres.
Surely there are more J cars than AMS cars??
