Hello all, new to the forum deal, but am a long time Pontiac enthusiast and owner (74 grandville, 85 bonneville, 99 grand am) of Pontiacs and have currently acuired an 08 GP GXP. Haven't ever driven or riden in once until i purchased this one last week, but have been searching the web in regards to one of the concerns i have with this vehicle. I noticed when on rough rural roads, those that have ruts, etc from tractors and big trucks, that the car has a tendency to follow these. It's an eye opener and makes you have to hold on. Anyone exerienced in these issues have any particular advice on what to look out for or possibly change or upgrade? Front tires seem to wear a little more on the inside and a little tread life left, but are nearing the end of their life span. Previous owner put Nexen S3000, i believe. Any advice would be appreciated.
