Hey everyone i was wondering for anyone that has 35 on there truck does it really make a big difference on pulling. MY sitution is i have a 05, 4.6 and 3.55. I want 35s but i pull heavy loads sometimes and i want to know how bad gass will go down. Bad enough i got 3.55 i wish it had 3.73 but i didnt buy it brand new and dont have extra cash for gears. Im geting toyo m/t's too. and i all ready have leveling kit and airbags

 

I'd stick with 33s if you aren't going to regear, personally

 

I agree. I'd stick with 33's.

 

is it just because i have 355?

 

I agree that you would be better off with the 33's. I felt a pretty good power loss with my 35's even with a 5.4 engine and 3.73 gear's.

 

I recommended 33's because you said you had a 4.6 engine with the tallish 3.55 gears and you said you towed heavy loads. If you never towed/hauled heavy loads you could probably get by with the oem gears and 35's.

 

should i think about 410 in the future? what will happen to mileage

 

im going to get the edge in less there something better that's also good for my tranny and motor

 

the edge will help out with shift points and give you some performance gains but i would look at the custom tunes forum if you are going to invest the money in that part of your truck. and to repeat what everyone else said, i would stick with 33's.

 

Your next thoughts should be gears. If I were considering a programmer in your situation, I'd put that money aside and save it up for gears. Looking back (since hind sight is 20/20) I didn't like my 5.4 with 33's and 3.55's. I went to 4.10's with 33's and would recommend at least 4.30's with 35's. Gas mileage...mine went up when I went to 4.10's. FWIW, 3.73's shouldn't even be a consideration even if you're going with 33's.

 

I agree, plus 33's will look better with a leveling kit - 35's look too stuffed without a suspension lift IMO.

 

I have 35's but am going down to 33's.

 

I have the smaller 4.6 L, 3.73 gears, and 35" tires. i tow fairly heavy loads, haul heavy loads, and do so in some less the ideal terrain. I pull up some incredibly steep grades, and do it often. no problems here. I do have plans for 4.88's in the future, but don't be afraid of the 35" tire. Your truck can handle it.

 

does anyone know anyone that knows how to do gears in DE or close that is good at it and cheap?
