I have a 99 limited 4runner just put 3in spacers in the front and ome 890's with procomp es1000's in the back and i am wondering what size tire i should get. my main concern is i pull a 3500lb boat on occasion even the boat ramp is only 1mile away i want to make sure i dont go to big. I was thinkin 285/75/16 on 16x8 rims what do you think??
