New Wheels

Hey guys Ive got a question, my brother just bought a new 08, its a XL, auto, 4X4, Its got the standard steel wheels, thats the only thing he wants to change on his new ride. He ask me what I thought and I told him I like the look of the 19.5 rims. What do you guys think. I know this is a difficult question because its more his decison. Are any of you men running 19.5, how do like them. Any feedback will be greatly appreciated.

Also he has the 5.4 and 373 gears. This truck is just a comuter, He will never take it off road or pull a load. I know what your thinking, why buy a SD and not use it, He just feel in love with it, didnt care for the look of the F-150. Thanks and good day.

Aren't 19.5s mostly heavy load / commercial tires? I think 18s or 20s would be a cheaper way to go.

I never like stock wheels and would probably change them too if I had the money. What color is his truck?

I'm pretty sure the 19.5 inch wheel/tire combo would be too much for the 5.4 to handle and would kill his mileage. When I went from an a/t to an m/t on my old F150 with a 5.4 it caused all kinds of crazy shifting. It was a 2000 model truck but I don't think the new one has the power to handle 19.5's.

Yes the 19.5 would be a heavy load rated rim. You might just want to go with a set of 20's...

But you will loose a little power... just becuase of the extra weight of the rims... but hardly noticeable...

Thanks guys, I dont know the name of the color but its like dark grey metalic. What I called a comuter , its really something he will tool around in. The real comuter is a 86 work truck. There is some things to think about. He has a car he drives when he goes out of town.

Yes, but as Layson said, the difference would be hardly noticible, if at all.

Rickson 19.5 wheels: Aluminum 45 pounds; Steel 57 pounds.
Bridgestone M729F: 265/70R19.5 87.78 pounds.
Total weight: Aluminum 141.78; Steel 153.78

I haven't weighed my tire/wheel combo but i have picked them up and I'm pretty sure it is less than 100 pounds.
An extra 45 pounds per wheel is going to make a HUGE difference on a 5.4L.

Ok, well, my '03 6.0L auto with 3.73s and 35" tires feels identical power-wise to my dad's '03 6.0L auto with 3.73s and stock 32" tires. Maybe larger wheels makes a bigger difference, but I have trouble believing this because its not just mass of the tire and wheel combo you are looking at, but its rotational inertia.

Also, I just did the math, the tire you listed is 2.5" larger than stock.

I went from 33-35 inch tires on my 6.0L and hardly noticed a difference. But there is a big difference between a gas engine and a diesel engine. I don't want to argue about this anymore, just offering my opinion.

And stock tire size is 33" so that would be a 1.5 inch difference. The 33" tire that goes on a rickson wheel is 10 pounds lighter. Still much more than stock.

Ok, maybe the gassers notice it more since they have no torque

Stock tire size on my '03 was 32" though, 265/75/16

(265mm tread width) x (75% sidewall height) x (2 sidewalls) + 16" wheel = 31.65"

new tires:

(315mm tread width) x (75% sidewall height) x (2 sidewalls) + 16" wheel = 34.6"

Anyway, back to the topic, the 19.5" tire/wheel combo will be a very stiff riding commercial setup and you'd be better off going with am 18" or 20" rim with D or E rated tires. D rated would be fine if you don't haul or tow much.
