I have a 2011 Chevy Malibu LTZ 4cyl with 225/50-18 Goodyear LS2 tires. The problem that I have is that the car loves to follow grooves in the road while traveling at speed (on the freeway, etc). I know that a lot of cars do this to some degree, but it is much more pronounced on this car than anything I’ve ever experienced.
I've heard/read that these OEM tires are not very good, so that may have something to do with it. The door placard calls for 30psi in all 4 tires. I've always kept them at 32psi. Just last night I increased that to 35psi, thinking that the higher pressure may help with the tracking issue. I haven't had a chance to drive on the highway yet, so I'm not sure. I have never had them at the recommended 30psi; that just seems too low to me. The sidewall max is 44psi. Another idea is that it’s the electric power steer assist that is causing this. Many people complain about EPS, but I haven’t read about it causing this specific problem.
The tires seem to be wearing evenly, and the alignment is spot-on for all measurements. The car (and tires) have 17,000 miles on them. The behavior has been the same since I first purchased the car with 13,000 miles on it.
Any ideas or thoughts? Should I in-fact be running the recommended 30psi? The manufacturer should know best, so maybe I need to follow their direction (what a thought!).
