I would like to put on some bigger tires on my 2004 Ford F150 4.6 STX but i am not sure how much it will slow me down. I am installing a 6"lift kit but need advice on how big i can go with tires without losing too much power. You know what i mean. PLease help

 

well it is my rule of thumb that if you go more than 3" taller than it is time to regear to regain lost performance and to releive the stress on you drivetrain, it is up to you the tire size but a 35" would look good under those wheel wells with a 6" lift maybetaller depends on you with 35" i recomend 4.56 gears good luck
