I have asked him how large is the difference between a Porsche Dunlop tire and the "same" non-Porsche Dunlop tire. He told me that all Dunlop tires (same model) are 98% equal. Only 2% are specific to the manufacturer. Also he told me that the load and security of the tires is the same.
White isn't black and red isn't yellow.
Meaning: you can't compare one tire manufacturer to the others.
And to go further: so there is "only" 2% difference at max? Where is that 2% difference? Tire profile, tread, etc.?
Did you actually see how a tire is manufactured? So you probably know that what the guy told you is a little bit...well, to say it blunt: hot air.
And if you don't "give away anything", why do car manufacturers like Porsche change the 2% you mentioned? Doesn't make sense to me, does it make sense to you?
Another thing: tire manufacturers have a non-disclosure agreement with car manufacturers. Even if if this Dunlop guy wanted to, he wouldn't have been allowed to tell you any details. So he served you "hot air", at the same time promoting his own company products.
Load indexes? Well, another interesting story and I'm sure the Dunlop guy gave you an explenation for that too.
Let's take a certain tire for example, same size, same name but one has a N0 added. The N0 tire is approved up to 300 kph, the other one only up to 270 kph (manufacturer approval). The N0 tire also has a different load index, not much difference but around 100 kg per tire.
Now some more food for thought: take a Cayenne Turbo, FULLY loaded at maximum capacity. Take a hot summer day with very hot asphalt temperatures. And let's say you do maximum speed for a few minutes. Well, I wouldn't like to drive the non-N0 tire.
This was just a very simple example, things are even more complicated in reality.
Dunlop produces great tires, no doubt about it. But I stick with Michelin, right now their tires really rock.
And to make you understand how much crap this guy told you: if he mentions a VW Golf with 700 kg max. load per tire and laughed about you mentioning the heavy weight of the Cayenne, I'm sure he also mentioned to what SPEED the 700 kg max. load is approved.
I bet it wasn't 300 kph.
Take a tour of whatever company you like, including Porsche and you hear only miracles. But in reality, you're just doing a promotion tour for a certain product, don't expect full honesty but expect a lot of "stories". I guess this is the same with all companies and there is nothing wrong with that as long as you hear the "other side" too.
