I have to replace my Pirelli P700Zs real soon. I was going to go for the P7000s(195/50/15). They seem to be a good tire for about $105 Canadian, installed and balanced in that size. ....But now I'm thinking about trying the Kumho Ecsta 712s. They're about the same price. Anyone have experience with either or have an opinion which I should choose? Thanks, John
