Re: Bias vs Radial slick
The 28x9 MT ET Drags measure 27-1/2" according to MT. Depending on how fast you are, it likely grows to 28" or even a little beyond. A radial won't grow. So if the radial you're looking at is exactly 28", you likely won't see much change in stripe RPM.
The key here is that bias tires grow while radials do not.
