Hello all,

I know there is a wheel fitment guide which is very good, but I'm a complete rookie, I'm will be fitting my truck with new wheels and tires this weekend,

Truck: 2004 f150 2wd 4.6l
- it is stock height, no leveling kit or anything.

I want to fit some 35s tires and 20" wheels, but I will be towing a 26ft boat, I have read online that these sized tires affect the towing in a negative way, so my question is what is the best tire size and wheel size without losing too much braking or towing. I would really like 35s


Thank you all in advance.

 

305/55/20 ...you will need a level kit in front ... 35’s will kill your boat pulling unless you want to re-gear.

 

^^ This ^^


Plus, read the entire sticky at the top of this forum titled "Tire and wheel fitment guide for 04-08"


Lots of good posts in that thread.

 

Thank you for the response, what about 33s would that make a big difference? And I saw the thread and read through it but it started talking about spacers and stuff which I wasn't sure about, maybe 33s with a suspension lift like airbags?

 

305/55/20 = 12.4 wide and 33.5 tall

 

Oh ok awesome those don't look bad at all, would you recommend, airbag suspension or will the towing with the size you recommended not be affected too much?

Thanks for your help

 

Depends on the tongue weight of the boat... once your truck is leveled and then you hook up the boat...it may squat in the back too much for you...this is where Air Bags would be perfect..

 

Dude you are awesome, do you reccomend a whole leveling kit or just the "strut" extensions? I read it in another post not sure what the diff is, if I need the kit would you reccomend any?

 

I thought another possibility would be a set of rear air shocks. Like an air bag, they can be inflated/deflated to allow height adjustments in the back. I used these on a Ford Ranger when pulling a small hybrid camper. They allowed be to remove any "sag" when the trailer was hitched, and then lower the truck back to stock height when not towing. Air shocks are good for moderate load; if you plan to haul heavy loads, then the air bags are a better choice. However, it does not appear that anyone makes air shock for these year trucks.

 

Spacer up front and bags in the rear...perfect
