I was on tirerack and noticed that its asking if my car was made before 3/2010 Is there a difference in the 2010 models?

 

What are you shopping for on tire rack? Coupe? Sedan?

 

There was a mid-year split regarding the TPMS on all 2010 Infiniti models. Depending on the build date there were different sensors used. You can check your vehicle’s build date on the VIN placard which should be located on the driver’s side door jamb.

Call me direct if there's any confusion.
