Need some advice 18s or 20s?

So...I've narrowed my wish list down for my next truck. I will go F350 - Diesel - CCLB - Lariat - ingot silver two tone.
#1.) If you have a pic of a truck like this...please share! I love seeing them. They are hard to find...I may have one built to my specs...
#2.) Would you go 18" or 20" wheels, and why?
#3.) 3.31 or 3.55 (I think you can only get 3.55 with 20s...right)? And why you'd select that ratio?

Is the factory spray in liner nice? Comments on it?
Does the FX4 package affect ride quality?
I live in the snow belt - lake effect. So, I am contemplating supplemental cab heater...worth it?

Thanks for helping with any of this!

I myself like the 20s with 35" tires or 22 with 37 tires it looks clean that way. I have 3:31 gears and mileage isnt to bad unless Im pulling somthing really heavy. Even then its about 10mpg.

I would go with the cab heater my friend has it on his f150 and it's amazing, like instant heat. So even if you have to wait for the truck to warm up you can sit and be warm.

18s mean cheaper rubber. Personally i like 20s. Im getting decent mileage with 3.55 gears. 16L/100km. But my truck only has 2800km on it. I live in Central Alberta Canada and the supplemental heater isnt worth it. All it is is for warm air to the cab. Personally id spend the money and get either a Espar or Wabasto diesel engine heater for the winter months. Your truck will thank you when you have one and starting it in -30C
And Ive also got the FX4 Package. Ride is exceptionally smooth. But thats gonna end for me soon. Skyjacker 6" lift will ruin that lol

Ucpa111,

I have the factory spray in liner and it is nice, but i havent abused it too much but it seems pretty stout.

As far as the FX4 suspension, the ride was smooth as mentioned but I only had it on for 1500 miles before the lift went on but it was a nice suspension.

I have the 3.55s on mine and it had 18s stock. Gearing is good for the stock setup.

Hope this helps with your decision.

If you are going to keep the stock wheels. Go for the 20" and the 3:55
tires for the 18" will be a little cheaper and there are more choices. But I think the 20" look a little nicer.

If you do any towing or heavy hauling at all, Get he 3:55 the difference in mpg is minimal. I get 20-22 mpg empty on the hiway, Around 12 mpg towing.

The Rapid Heat isn't going to warm up your engine faster. But it does help take the chill off the cab faster than waiting for the engine to warm up. I think it's worth what it cost. Plus it comes with the Heavy Duty Alternator.

Go with the 20s...tires are more expensive but looks way hotter !! The rapid heat is well worth the money IMO

The 20s look way better, and I love the Michelins that come on them. The 18s just look cheap and the tires are tiny compared to the 20" tires.

So, go with 20's if you don't mind spending more money for tires that you are getting just for looks. There is little or no difference in performance or tire wear. Keep in mind too if you get 18's and then want a taller tire to fill the wheel wells, you can do that.
