See this is what I felt when I test drove it. That's why I didn't feel comfortable and got the impression that maybe it was just too much for me.

 

I've had other sports cars with wide tires and I've never felt this. I've also never had Bridgestone tires before. (Usually Michellin or BF.Goods)

 

This has a name. It's called tramlining. Low profile tires are more prone to it, but the G37 does not have especially low profile tires. Some models of tires are much more susceptible. The predecessor to the Bridgestone RE050's which come on the S model, the RE040, was notoriously bad. I had them on my BMW 330 and it had a mind of its own. I do not notice it at all with the 050's on the S.

 

wide grippy tires = channeling...or tramlining as said above^^

I had this on my IS 250 and experienced it on a Porsche that I test drove...

I really think it's just a function of the reeeealllly wide tires finding themselves or centering in the channels on the highway....

I think making sure they stay inflated to exact right PSI helps keep this to a minimum.

Some companies overcompensate the steering feel to very tight to "fix" this...but that leads to very heavy steering...another bad feature of my former IS250

 

Dunlop A/S tires also...........

 

yeah i noticed this and just figured it was the car's way of hugging the road...like when u drive on road that is ridged or something the car sways left and right by itself.....

 

yup yuppp... ^

 

what he said. the sticker/wider the tires, the more the tramlining.

 

well it sucks sometimes, but at least I know it's nothing wrong with my particular car. luckily, there isn't a lot of those kinds of roads in my area.

 

i do not think i experience this. probably because i havent notice it yet. how bad is it. you are driving on the highway then all of a sudden the car just move without you doing anything to it?

 

My 350z with staggered 19 - Rays wheels/lowered had this issue as well. Downright scary at times. My G has done it, but far fewer times. The first time it freaked me out a bit.

 

Eery thing to do with the wider tires. Even notied this with the Maxima when i went with wider pilots on it.

 

The darting behavior stems from the second gen FM platform, at least the way the Factory has it set up. It is more noticeable as you go to lower profile tires. I haven't had any chance to play with alignment settings yet, and it may take me awhile to have the chance. But, I do notice an improvement by running one more pound of air pressure in my front tires than the rear (even though the Factory says use the same pressure front and rear).

 

Well well... so it does have a name and is quite common. I wondered about that. It never happened on the highway but it did that to me a few times on backroads and city roads. I'm pretty much used to it now so as long as it's normal, it's all good with me.

 

10 and 2 is the only way I drive with my hands on the wheel at high speeds... Actually 9 and 3 so that I can change the stations and stuff... Keeps me in control and going in the direction I want to...
