sport suspension and low profile tire

[MRider]

I have an '06 M45 with sport suspension and 19" low profile tires. Wondering if it's normal with this combination that the steering wheel is very sensitive to road conditions. The steering gets pulled (left or right) when hitting pot holes or uneven roads. I think there's a term for this. I had low profile tires and springs lowered on different cars before but never experience this much sensitivity as I do with the M45. Is this normal? Can this adjusted with stock springs and suspension?

The Goodyear RSA's are notorius for "tramlining". If that's what you have in all likeness that's your problem. I'm also not crazy about Bridgestone 050A's after 12K miles are on them. They ride rough and are noisy in my opinion.

I had RSA's then switched to PS2's and all is well now.

Bottom line, the way to fix it is purchasing different tires.

Great! Thanks. I still have good tread on them so I'll have to stick with them for now.

i have the same problem on my non sport M45 with 19" sport tires. the car pulls to the left or right depending on the road conditions which sometimes suck

5Liter, what kind of tires do you have?

I've been told by non-Infiniti owners that Korean made tires are pretty good as long as you get the higher grade models. That's like 30-50% cheaper than Bridgestone/Goodyear/Michellin. Anyone have any opionion and or have personal experiences with them on Infiniti cars?

Just put on Vredestein Ultrac Sessanta tires (245/40/19)OMG - these are just as good as the Goodyear F1 GS-D3 tires that I just replaced. Check out the following youtube video on these tires:
