In the "street semi" range ive tried the RSR'S, KU36'S & currently running the RS3'S the Hankooks are light years above & beyond the kuhmos & federals imo
The invos probably dont give too much dry grip away to the federals or kuhmos but absolutely hose all the "street semis" in the wet and are quiet as hell for daily duties so its obviously a trade off..
The hankooks are pretty nervous in the wet but better than the other 2 brands lol.
Hope that helps
