First of all I wan to apologize if I break rules here I am new on this and not good at it.
I joined because I have a 2005 Z convertible 6 speed with 47 k Original miles on it. I am about to replace my forth set of rear tires. I read some of the post on this issue but them I can not find them any more.
I have called Nissan direct and talked to several dealers and I mainly get " you bought a expensive sports car so it is going to cost you to drive it.
With out getting longer on this post can someone tell me if any one ever got any were with Nissan on this issue. I know that in 04 there was someone trying to get people together to go after NIssan.

Thanks, I will try to learn more about how to use this forum

 

I would suggest 4 wheel alignment and go with a harder rubber compound. I am running Continental DWS 275/35/19 on my Z, 16,000 kilometers with little noticeable wear. They hold the road well and handle nice in the rain as well!

 

Possibly your driving style might be causing the problem. You might need to use a light foot on the throttle.

 

I would check air pressures and rear alignment. They will wear faster in the back but that sounds a tad excessive.

 

You are averaging 11,740 miles on rear tires?

Are you smoking tires from every red light?
