If you have just paid a small fortune for tyres which possibly dont suit the car, are you really (a man thing)going to eat humble pie and admit you have bought some lemons. Where as if you had paid a lower price..
Ah I see, well, I guess that depends if the owner understands the problem. It's a big trap to fall into. I spent a good while thinking if a tyre is bad, it's bad. That's it. Ie all Falkens are bad, purely by brand name. I'm beginning to think they might suit a small wwd shit box with rock hard suspension and harsh unforgiving chassis. But that's without fully understanding the problem.
It certainly looks like I bought the wrong tyres on the front of mine, sc3 ao1 tramlining all over the place, where as sc3 mo where fine. ....ffs.
Then on the other hand there's certainly some obvious traits among manufacturers.
Dunlops have a few models that give an exceptionally tight accurate ride without being harsh on the omega. They seem to have addressed the noise level they where renound for too.
Michelin seem to think all car owners want massive mileage at the expense of lateral grip.
Bridgestone think all suspension should be rigid. (Completely unfair comment as I've only sampled one of their tyres)
Continental have blown all those theory's out of he water as they have two sc3 sub models that behave completely differently.
