I agree the new IFI wheels are good.
Many previous threads have explored the observed principle that wheel traction depends strongly on material and texture, while it is mostly independent of contact patch area. So 2" wide wheels don't grip (much) better than 1" wide wheels if other parameters are equal.
However, double the width means half the load-per-contact-area and therefore half the wear, so wider wheels will keep their traction longer -- i.e., more matches between tread changes. And wider wheels will resist twisting more than narrow ones, so defenders will have to work harder to force you to change direction -- and your own motors may also have to work harder when you want to change direction.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
