Ok i have a 2005 1500 z71 seirra. Im going to need tires soon whats are there are the stock bridgestone dueler a/t P265/70/R17 they held up well 40K but id like to get something with alittle more rubber and maybe a more aggressive tred but at the same time I dont want to kill my gas mileage. anyone recommend aything? Id like something pretty hard so they last. pics of tirers on trucks are cool too if you have em.
