You get 30K miles out of some tires your not driving your car right. :tup:

^ hahaha if you never turn VDC off you might have a chance. I'm already saving up for my next set of rears. General GMAX

What people are either not telling you or don't understand is these warranties are only valid if you rotate your tires. With the Michelin PSS, they only give you a 15,000 mile warranty if you can't rotate the tires. I would assume almost all brand are similar with the warranty. The tires may last longer but the warranty is shorter. Obviously on the 370Z we can't rotate our tires.
