Manufacturer-specific tyres

[johnnyBv8]

Seem to see a lot of tyres rated by Porsche (N1, N2 etc) plus some for Mercedes. I assume not, but is there any reason that these cant be fitted to any other car?

Very old thread.. But i'd be interested in hearing the answer..

Does wheel design play a part in this ?

In my experience no - they are just slightly different compounds.

I very much doubt it. Manufacturer specific tyres are more about slight differences in the tyre compound and construction to fine tune the performance and dynamics that the ride and handling team wanted.

On higher volume/cheaper stuff generally it's done the other way round. There may or may not be the facility to choose a particular manufacturer and a selection of sizes and load ratings may be available, but by and large the engineers tune the chassis as best they can with what they're given.

No wheel fitment problems at all, usually they're different compounds but occasionally slightly different construction too but will work fine on other manufacturers wheels.

You'll only run into wheel problems with the GTR tyres.

N and K rated tyres can be quite different from the aftermarket versions, a lot of the other markings are simply a way of getting people going back to the dealers.

I had BMW M3 Continentals on my RX8, it drove fine, no problems.
