I fitted some 19's at the weekend, and since then I've not been achieving as high an MPG than with the 18's fitted...is this normal? The rolling radius is only 1.55% difference, as the tyres have changed from 225/40/18 to 235/35/19. And I'm not sure if it's just my imagination, but it feels slightly slower too.
Not sure if this helps, but I also now get a fair bit fo road noise, and my old front tyres were worn bald on the inside edge.
