I think this will help stupid people pick a tyre better than the worst simply by informing them how much worse the cheap tyre is. We have all been there when buying anything - 'oooh i could get one slightly better for only a fiver more'
Well it would but the rating categories seem to be either so vast or so wrong that only the absolute worst of the worst is getting lower than a C. Mid range tyres are getting A ratings, with great rolling resistance scores too, whilst some high end premium cars are even seeing their rating for grip drop to C, just based on manufacturer fitment.
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.
Take the SportContact2 I currently run in 205/55/16 91 W.
Eff: E
Grip: B
Noise: 70dB
£77 fitted.
Ah but
SIR, you have an
AUDI, you should buy the Audi endorsed variant.
Eff: F
Grip: C
Noise: 71dB
£85 fitted.
Really? Just because Audi endorse that particular tyre it suddenly becomes a whole grade less efficient, with worse grip and more noise? Yeah, sure it does.
Perhaps I should look at some alternatives, like the Hankook Kingery Eco - B/B/70 for £72, or wait, the Kumho Solus KH17 is just as good as the Conti, E/B/71 for £63.
Apparently if you want the best grip in this size, you need only look to the Michelin Energy Saver + or the Michelin Primacy HP. If you don't like Michelin, there's always Hankook's midrange tyre, which outperforms their own performance tyres.
It's absolutely barmy really.
