So I am debating on getting either 33s or 35 inch tires. I know if I get 35s I'll probably have to do a gear ratio tune so it last with out problems . I'm pretty sure I have the standard gear ratio. Right now it came with 31 inch tires. If I just level it and do 33s would I still have to have someone change the gear ratio ? Also how much total height wise would it change everything. I have a 7. Foot tall garage and I believe even with the shark fin I have 5 inches of clearance. Does a leveling kit really change the overal height when I'm only bringing the front up 2 inches?
I have a Readylift SST 3.5" lift and after trying LT275/60/20's, I changed to a P rated in the same size.,.which equates to a 33" tire. Few reasons I went this route. First was gas mileage..35's and an LT weight tire, really eat into the mpgs. Second, 33's you have the choice of P or LT rated still, 35's you dont. Honestly, LT tires are overkill on these trucks unless you run it off road a lot or with a LOT of weight. Third, with the Readylift kit, the preload spacers stiffen up the suspension, so with LT tires, it felt like I was running cement tires, i just felt every pebble on the road and it hit potholes really hard. Possibly leveling shocks on the front and not the spacers would be a better combo with LT tires. Lastly, LT tires are just plain heavy, rough, not great in wet conditions normally. I just couldn't justify the LT tires over P rated with my driving style. I do haul my atv in the back and yes, P rated tires tend to be a little squishy if you don't air them up a little more, but nothing serious if you get good quality tires. The ride comfort the other 99% of the time is sooooo worth the little trade off of a stuffer tire for the 1% of time I tow or haul. 33's by the way look great with the 3.5" lift. It has some space, in the wheelwell still, but the 33' suits the look I find. 35's would fill that space more, but looks fine with 33's
