What's the point of this?

Thinking of taking this off, but I don't even know the purpose of it in the first place. Anyone know sorta feel dumb asking but I guess you don't know, if you don't ask.

 

It's an annoyance that gets hung up on bigger tires, remove it and don't look back.

 

Air managment and to keep spray off the suspension would be my guess.

 

designed to improve fuel economy (aerodynamics)

 

Toyota wanted to add something to rub on rocks.

 

That's the reason why I was thinking of removing it, mainly lol to fit bigger tires.

 

Noticed that about a week ago on my 5 Lug, removed that stupid looking thing and left the bolts in there.

 

This.

They are called wheel spats and split the air around the tire.

 

Its a miniature mud flap. You know, for reverse and stuff.

 

HAHA ... yep must be good for a +5 MPG gain

 

I did notice I got 0.754 less MPG after taking them off.

 

Take your wheels and tires off, you gain like 18 mpg in town and 20 on the highway!

 

After how many tanks?

 

On my last car I strapped C4 to it and exploded it.


Got like +7 MPG from that mod. Well worth it.

 

Eleventeen

 

Schfourteen teen?

 

There goes my gas mileage out the window, I will have to give you a report after 11ish tanks less gas mileage hmm maybe I can go faster..

 

It's Eleventeen John, get it right.

 

Eleventeen Right. No more reverse mudding for me... Lol

 

I believe you are correct. The new Silverado has them on the rear wheels.
