Hoosier says this because their is camber built into the tire. Air them up and check it out for yourself.

yeah cus nobody false advertises. or puts stupid stuff on the internet or their websites... look up in this thread, camber, cus they say so, to compliant...Originally posted by oldtrackchamp4x View PostI don't turn mine. The reason i don't is, when Hoosier Tire says: "Circle track racing tires: (includes both dirt and asphalt tires). Hoosier tires must be mounted with the SERIAL CODE located toward the infield." I don't think they are trying to sell more tires or just saying it for the hell of it. I'm pretty sure they know why they want them run that way. JMO

So stock car driver once again you are right, in your mind. It could be proven beyond any doubt, and you would still argue the point. Like i told you before, G O F U C K Yourself. JMO

Idk what Hoosier mod tires you are dealing with, but the UMP D, A, and H do not have camber built in. I don't know of anyone that doesn't flip their tires to use the best edges. And I've never seen one of these tires flipped and become "too compliant". Hoosier proves over and over that they are about their pocket, not the racers. It's not in their immediate best interest to tell everyone how to make their tires usable for a longer time by flipping them. They aren't referred to as the Purple Mafia for no reason....

Side wall compliance. The tire is also a spring if you think about it. Sidewall compliance dictates contact patch dynamics. You do not want the contact patch to distort. When this happens you lose traction.Originally posted by HuckleberryB4 View PostWhat do you mean exactly, by "Too Compliant?"Find me on Facebook: Impetus Dirt Racing Technologies

distortion is traction, if the sidewall wasn't compliant you would have no side bite and no forward drive.

I posted but it was lost in that whole missing day issue.
I contacted Hoosier a few years ago about the mounting issue, they recommend serial numbers to infield because the way they put the rubber on the tire carcass. Running it with the serial number to infield runs it with the grain they lay it, premature tire failure could occur if ran opposite. The issue is more pronounced on asphalt or high wear dirt tracks, and is rare. Once the tire goes through a heat cycle your fine to flip it as often as you want to.
They also stated that only some of their sprint car tires are cambered, only some. If you have any mod or late model tires showing camber it is by pure chance.
Yes tire distortion is a major component of traction, a solid rubber wheel has almost no grip because it does not comply, that said too compliant can cause tire shake. You can see it on some slow motion wingless sprint cars.
