If these things work, won t manufacturers put the OP oitmof business by simply moulding them integral into the tyrewall?
Until there is some independently reviewed evidence I too believe this is more suitable for the corrall.

Triangular
Looks like they'll be "cutting through" the lengthwise vortices as the tyre spins, and generate a vortex of their own , but a vortex that's continuously moving down (on the front side of the wheel)

Totally looks like 100% increase in FE!
Why claim only 20%???
22 to 28 is more like 25% anyway.
I reported it as spam before there were any responses at all and here we are.

Ah, when they don't work, I can always use them as vortex generators

I tried to Google "rocket tab" and was rewarded with this result:
"RocketTab is an adware program that displays pop-up ads and unwanted advertisements on web pages that you visit."
I know OP is selling something and I already know its snake oil content is very high. I just really dig the juxtaposition of names, products and market welcome.
I wonder, though, if the snake oil content is deliberate. If OP conducts thorough testing in consistent conditions and revisits his claims - especially to refute them if they are disproved - I'll give him the benefit of the doubt. It's more likely that unintentional bias has affected the behavior of the drivers. It happens.
Much better testing is required to determine whether the tabs are doing anything at all. I strongly doubt it.
But there's no way in hell I'm dropping $25 on these things. Even if testing somehow shows them having a measurable effect, forget it.

If the tabs on the curbside get scraped off, does the vehicle spiral into a ditch?
P.S. I will answer my own question: Not if the Ram Implosion Wing is angled a few degrees to the right.

elhigh, ya got me thinkin'... there are a zillion cheaper sources- or maybe just take them from the baby and give it a cardboard box- PLUS they have other shapes to play with!!! Maybe the best Rocket Tabs are moon shaped?

It looks like the cross section of some cheap plastic moldings from Home Depot. I could make a bazillion bucks selling these things to the gullible, just buy up fifty bucks worth of molding, slice off 12 little sections, sand them a bit to get the base profile right.
I could...but my conscience won't allow it. Plus it'd be difficult to convince people they're really for cars when they still have that attractive maple woodgrain.

Back from a weekend of camping. I would like to send out some samples. 10-20 sets for you to try. I would need a ship to address. Please email me at davekacz131@gmail.com. until I get all the corrections to the web site.
