2mpg that's awesome, I knew it. Thanks ChrisD for the info

who's got a couple of grand for me?
No problem, but tirerack states your tire in your size is 17lbs..

look for "tires" then cross refference the size..

If the moons help the cd at 120+mph and didn't help some at 55 mph, I would be very surprised.
It's not like they are active device like a spoiler or VG, to my eye, they are pretty passive.
Kinda like rolling up your windows when you drive over 30.. It helps.
Your vertical 4x8 plywood tailgate setup is hardly compairable to hubcaps..

If the moons made any improvment, I'm sure EVERYONE on here would be running them.. I've read lots of a-b-a results and nothing showed any results...

my windows down vs up at 55mph doing a-b-a-b showed no signifigant change in FE on my truck utilizing my SGII and using the same distance stretch of highway..

I think my window visors have something to do with that, not sure..
thats another a-b-a test onto itself..
