Michelins, got right at 70k from the originals & already 50k on the new t set which still have plenty of tread left.
Yea, they cost a little more, but from my experience with other brands, GY, Firestone, Bridgestone, Falken, & Yokohamas 38-40k has been to max mileage of all the others.
The Yokohamas were be best of those listed, the Falkens were the worst, GY & Firestone seem to get square in about 25-30k & can never get properly balanced from then on & the Bridgestone only got about 35k.
