Tyre homologation -does it really make a difference?

Bertt · 04-08-2012, 12:12 PM

Dear friends,

Pretty soon I have to get new rear tyres (seems a bit of a common thing with 550's

) so I am checking on what to get. Now I am a bit puzzled about the different homologation markings. For instance there are multiple Bridgestones and Michelins in the correct size (295/35-18) but with different homologations and prices. Most of the tyres I can find in the Netherlands via online tyre suppliers seem to have a Porsche homologation (N0, N1 ...N4). Also found some with a BZ mark (according to Bridgestone this means Bridgestone Original Equipment). Haven't found any with a Ferrari homologation. Would it make a difference if I choose the ones with Porsche homologation marks (these are available and even cheaper than the ones with the BZ marking) ?

it could make a difference...

I had a difficult time trying to replace some Pirelli tires on my 928 Porsche ( back in the day ) and we could not make a couple of other brands ( major ) work... worked with tire dealer, who worked with tire manufacturer to resolve issues... final result was that replacement tire manufacturers refunded my purchase price of their tires and suggested to stay with Pirelli that worked well

it was not a scientific effort, but an effort non the less that deemed that Pirelli had a construction that was better suited to the 928's suspension etc... indicating that your question can have merit... there may be more to a tire than the correct size and performance specification on the side

there are several car and tire manufactuers that advertise their collaboration on developing the car and its' performance with the tires
