Currently running BFG KDWS' and there is a definate improvement in ride quality with them compared to the stock Eagle ZR's, but I think my next set is going to be GY Eagle F1's.
I never thought I'd buy replacement GY's ever, since all their other tires are such garbage, but I've heard and read nothing but good things about the F1's.
Nitto's are Junk! Their DR's suck too!
