I've had a rethink on keeping the stock tyres after driving on them in cold weather where normal "summer" tyres perform badly i.e. < 7C. I was pleasantly surprised by the amount of grip the stock tyres offered to the point that I will likely keep them as the compound must be a little softer than normal for them to work so well in the cold and wet.

Shame the i8 specific compound isn't available in larger S001 sizes! I want larger tyres as a little extra rim protection from the kerbs - the grip levels are fine for a road car.

Incorrect the S001 is avaliable on a 275 35 20 with the same compound as the stock sizes 280 A A

This is not advertised as an i8 compound. How can you be sure it is the same?

The fuel efficiency and wet grip ratings differ between the 275 and 245 i8 tyre. This means they are not the same compound.

You've listed complete details of the actual i8 tyre but just said that as the treadwear, traction and temperature grades are the same on the 275 then the compounds must be the same.

Here's what is listed on the site I tend to buy tyres from:

http://www.oponeo.co.uk/tyre-details...32420799_label

This shows the compound as F (efficiency) and B (wet grip - braking)

The other 275 available:

http://www.oponeo.co.uk/tyre-details...-ro1#124991763

This shows the compound as E (efficiency) and C (wet grip)

These are clearly two different compounds and potentially sidewall construction as the ratings are different.

Now let's look at the actual i8 tyre:

http://www.oponeo.co.uk/tyre-details...w-i8#132037890

This shows the compound as E (efficiency) and A (wet grip)

Again different compounds. Highlighted by the wet grip capability.

The load ratings of the 275s and the i8 tyres are also different. Potentially highlighting different sidewall characteristics.

The 280 A A that you believe means the tyres are the same is not sufficient to make that assertion. Have a read of:

https://www.tirerack.com/tires/tiret....jsp?techid=48

One of my friends works for Nissan and his job was specifying and testing the compounds, sidewall construction, etc for their cars. There is a lot more to a tyre'a construction than data you're using.

As you wish don't buy them I have over 14 years in the wheel and tire industry so I think I know a little bit a about what compound means and how it's rated.

I'm CTO for Avon/Cooper tyres in the U.K.. He hasn't answered a single question I've raised. Classic Internet forum BS.

Do you want to believe him?

And whilst you do, from safety, tyre performance and insurance coverage perspectives please explain why it's ok to fit a much wider tyre to an i8 stock rim when the tyre specifies a wider rim than stock is needed?

That was not your original question, as you may go back and see on your prior post you were asking about the compound of the tire. I am not wasting any more of my time and effort to explain things to somebody that it's set his on way or the highway, please don't bother on replaying as I am done with your none sense and/or the conversation. (Let's see if you follow instructions)

Stick to the thread and do something positive thank you..

Do you want to believe him?
Lmao now he works for a tire company, before it was that his friend was a pilot on testing tires for Nissan... (Specifically on compound and side wall) What is next ? your wife measures the lifespan of the tires for NASA, I think everyone here gets the point of who is putting up the classic BS of the forum.

Here is partly what I suspect SteveB is referring to. What follows is a list of available Michelin Pilot Super Sports tires in 20".

There are several variants of Michelin Pilot Sports tires that are possible options. Here is a list of sizes for the MPSS:

I've opened another thread on this specifically for MPilot Super Sports. Hopefully somebody can help, If you fancy a 170 experiment you can get a Michelin Pilot Super Sport slightly wider for the front, Michelin do the rear sizes, i just need someone to tell me if it rubs. I would have thought 5mm would be fine on either side????

Do you want to believe him?
Lmao now he works for a tire company, before it was that his friend was a pilot on testing tires for Nissan... (Specifically on compound and side wall) What is next ? your wife measures the lifespan of the tires for NASA, I think everyone here gets the point of who is putting up the classic BS of the forum.
You don't get it do you?

You haven't a clue who I am, what I do or what the guy with 14 years of alleged experience really does either.

His posting looks to me like classic forum bullshit/trolling/whatever. All I'm asking are questions about tyres and suitability for our cars from a safety and legality perspective. But he's chose. To throw his toys out of the pram and not to answer. Perhaps because he can't...

I don't work for a tyre company. But I said I did on a forum so that must make it true. Like Mr 14 years said he has worked in the tyre industry on a forum so that must be true also - or perhaps not?

I actually worked for three Anti-Virus companies for 20 years but I don't know how to write a computer virus (Malware as they are more fashionably called!). So 14 years in the tyre industry may still make him unable to answer my questions....

The sad thing is that he can't even bother to answer some basic questions about tyres which his boasting of 14 years of experience in the industry would suggest he should be perfectly capable of. And in the spirit of the forum and helping fellow enthusiasts it would be nice to learn for his experience - if he actually has any!?!

But I'm not too interested now and will have a word with my friend who I know does know his stuff!

Thanks stress - someone who gets it.

I'm going to my friendly tyre place soon and getting them to switch front and rear tyres on one side to see if they fit, look ok and clear.

And I'll catch up with my friend who I know and trust who has done some real work in the auto industry on tyre specification.
