Looking for Z-rated tires

Hey so anyone know a good Z rated tire that comes in a 245/50/r18 and a 265or275/50/r18 I cant find anything from BFGoodrich which I usually roll with.
Was looking at the g-Force T/A KDWs but no dice after 245.

lol NM think ima just run a all around set of these......

What you guys think?

you dont want the bfgoodrich tires they are hard concidering what else is out there look more at the mickey tompson et's or there is one from nitto that are alot better. that is what i am going to i have the z rated bfgoodrich on the vette now and they suck for puting it to the road. i figure the bf stands for BeFore you buy a good tire...lol

Yeah ima end up running a set of Nitto Invo i think didnt have the exact sizes i wanted but that ok I hear nothing but good reviews about them from alot of high hp drivers.
