did the factory get involved?

 

Excellent thread! I just bought my 2010 G37 and also face the tramlining problem.

I have ZEXIUS OHTSU 225 55 R17 M+S 97V tires.

I am ready to replace the tires, but there is one thing that concerns me. When the car tramlines - I absolutely don't feel it on the steering wheel. No pressure on the steering wheel at all, but the car suddenly changes direction.

Does it still look like tire issue, or should I look for the problem somewhere else?

The dealer says they have done the alignment and the problem is in tires.

 

I just replaced our 2009 G37x (good Pilot Sport AS 3 tires) with a 2013 G37x (with somewhat worn Dunlop snow tires). The way this newer G37x handles is driving me crazy.
It seems to want to follow/wander to where ever it wants to go.....

I really hope this is due to tires....

I will try my other pair of snows that I think are in better shape and then in the spring by some new summer or all season tires...
