even better once you get rid of the noisy Michelin energy saver tyres /forum/images/IoniqForum/smilies/tango_face_smile.png

They are not so quiet and not as energy saving as advertised.
Mine are Michelin Energy Saver 205/55R16 91H which have EU Tyre Label:
E (energy saving), B (wet braking), 70 dB (noise)
(https://www.mytyres.co.uk/rshop/Tyres/Michelin/Energy-Saver/205-55-R16-91H-GRNX/R-153733)

Part of the shops shows a bit different label for them (or rather for a model branded with 'MO' = Original Equipment for Mercedes):
B (energy saving), B (wet braking), 70 dB (noise)
(https://www.mytyres.co.uk/cgi-bin/rshop.pl?details=Ordern&typ=R-167144)

Why can't Hyundai use better tyres like e.g. Pirelli Cinturato P7 Blue 205/55 R16 91V AO ? /forum/images/smilies/confused.gif
A (energy saving), B (wet braking), 69 dB (noise)
They are even cheaper...

or Nokian Hakka Green2:
A (energy saving), A (wet braking), 67 dB (noise)

H & T are rated for 50,000miles limited warranty
V & W are rated for 40,000miles limited warranty

So you lose a bit over energy efficiency, but you get 20% longer life instead. Feel a bit better now?
