Any experience with slipping tires on carbon rims/wheels and 300+ HP?
The stock rims got this nice straight knurled sides in the rim to support the hold of the tire, right?

The Rotobox wheels actually come with an anti-slip coating on them from the factory.

No chance of slip using DOT street tires using Rotobox or BST's for the H2's. As mentioned, the Rotobox wheels come with Factory anti-slip, front and rear, at no additional charge.

We do offer an anti-slip coating service for BST wheels here at Brock's: UHS Anti-Slip Coating | Brock's Main Store although we have had no reported issues of tire slippage (front or rear, road race or drag, street tires or slicks) when using BST's out of the box from H2 or H2R owners.

Brock, not sure if you saw my thread on "unusual tire wear" but these where the pics I posted from what appears to be the carcass of the tire folding in under the torque. If that is the case I would think there is tire slippage on the rim here. The tire is a GPA Pro and the rims are BSTs.





racer172,

I had not seen this post. But I will forward these images to BST engineers gather their input.

I'll get back with you.

I think I like the weight of the Rotobox.
But, I'm wondering if a crosswind would influence the performance?

Rapidroy, I like your dry sense of humour I almost took that comment seriously

rapidroy1,

We have raced land speed at the Ohio Mile (OEM wheels) and Mojave Magnum ( Rotobox) and I can tell you that our riders report the Ninja H2 is a poor handling machine above 190 MPH with the slightest side wind. Above 200 MPH, it's downright scary in crosswinds above 3-4 MPH. At Ohio, Zack Millholland aborted every single run, except one (219 MPH in the mile), due to 5-10 MPH crosswinds. At Mojave, Sport Rider Editor Kent Kunitsugu was able to run 199 MPH in a 20+ MPH crosswind to obtain his license! His 226 MPH run was with a 5+ MPH 3/4 cross from his right thigh. He was amazed at how well the bike handled the wind with the Rotobox wheel design. My 2 cents: although the spokes are 'wide' on the RBX2, their oval shape aids in aerodynamic stability at high speeds.

racer172,

Reply back from BST already:

Hi Brock,

He needs to mark his tire and rim with something he can rub off the rim and see if the tire is actually moving. If the tire is actually moving, then it should go out of balance and he should feel it. What is unusual is that bare section just before the thread cut on the tire. Personally, I think it is a thread pattern on the tire and might be by design, as the rest of the tire wear seems normal? I cannot get my head around perfectly spaced sections of wear on a tire corresponding to a thread on a tire not being related. As you know, If the tire is slipping anti – slip can be applied to the wheel.

Regards,
Gary
