Lightweight is for one thing and one thing only, ET. It's lightweight because there is less tread face and therefore they won't last as long as the non lightweight version.

That said, I run Hoosier's 32/13.5 radial which by design has a stiffer sidewall than a bias slick, on my 3144 lb. former GT Super Stock car with a 900+HP BBC under the hood and won't run anything else.
