It's ok, I can get the same A rated grip for my car with some Michelin Energy Saver+I'd also get a B for rolling resistance, I bet your waste of money premium tyres don't manage that

[TW]Fox;23081976 said:I wonder if it's got some daft EuroNCAP style logic in it where the tyre is rated against other tyres in its class, therefore making a 13" Energy with an A lower rated than a 19" Pilot Sport 2 with a B....
I think rolling resistance is really easy to understand :s (ISO 28580)
It seems you can use any method you want within the method.

i think these ratings are actually showing up some of the big brand expensive tyres as you can clearly see that some of the cheaper brands ie falken / kumho are better rated and a fair amount cheaper!
This can only be good news as premium brands will have to lower prices surely?
It would be great to hear from the top 3 or 4 UHP tyre company's on these ratings, no doubt they are a little confused by them as well.

The way these ratings have appeared, it seems to me it's only going to reinforce the view that high end tyres are just for 'boy racers' because all the mid range tyres have just as good scores, so must be just as good.
According to the stuff on BlackCircles, it's the manufacturers themselves assigning these ratings.
So it's Michelin themselves giving the Energy Saver+ the same performance rating as their Pilot Sport 2 premium performance tyres, and it's Hankook themselves rating their mid range tyre Ventus Prime as superior to their performance Ventus Evo.
It's absolutely bizarre.
