Yep,
I was looking at the difference between PS4S and PS5 as my rears are coming up for replacement and sorted through a few articles to get reviews info.
I happened upon a test called PS4S versus PS4S - weird. Anyhow it looks at the PS4S fitted by BMW as an OE tyre as opposed to the PS4S we all buy from dealers to fit after market and the differences are quite large.
Article is below for any tyre geeks to mooch through - interesting read....

So all that time and money in development and it's slightly better in the dry and more slightly worse in the wet. lol
 
An acquaintance in the tyre industry says motorbike OE tyres are not the same as regular tyres, even if exactly the same model. OE tyres are a substandard product, cheaper, to keep MSRP down. So he says.

The tyre fitted by BMW is OE.
The tyre we all buy from the dealers is OEM.
 
Amongst other reasons the rolling radius are more closely matched for x drive versions ..OE versions are specially marked to signify BMW approval :thumbsup:

Thanks for that - amended!
 
Its very common for OE items to be slightly different to the retail products. In the mountain bike world for example Fox forks fitted to the bike you buy from the shop might have plastic adjuster dials whist the retail version will have anodised aluminium.
 
It is very common for tyres coming on a new car to be different from the ones available to the public despit being the same brand and displayed model, whether it is a Renault Clio, a Range Rover or a Z4. It is because the car manufacturer wants and can afford the development to have a tyre specifically suited for the car while the one available to the public (or through dealership) is more of a compromise.

I guess for example a PS4S that would come on a Z4 could be biased towards more grip and silence to make the car feel good when new while the one directly available from Michelin might try to squeeze more endurance because you might care more about the life you get from the set of tyre you paid yourself.
 
One assumes that tyres with same trade name made at different factories around the world.
Do they adjust compound for the market conditions?

One video i watched it was suggested rental cars, especially EV's have harder compound tyres due to weight and excessive wear.
