I have a 09 hhr I want to chang tire size from a 215 55 16 to a 215 60 16 is that possible? I want to get away from the performance tire that was put on at the factory.

 

Yes,and usually cheaper sometimes with a longer warranty and a lower speed rating (113MPH instead of 121MPH). I would not call the factory tires "performance", most people use the word "crap".

Much discussed topic, use the search tool.

 

So what your saying is the 215/60 16 will work on my 2011 Panel ?

 

Assuming you have 16" rims, yes. But be aware of the different speedo reading, it will say your are going a couple of MPH slower than you are. Calibrate with GPS.

 

Here's a tire calculator that can help you "try" different sizes, and see the speedo error that results from them. I used to use it when I was trying to improve my gearing in a previous car for autocross.

Assuming you are shooting for more comfort, you may want to try something narrower and higher profile. Like a 205-60-16, maybe. Ideally, you'd like to maintain the same outer diameter and add rubber in this case.

 

Oddly enough my 2011 with stock 215 55 X 16 had a speedo error of about 2 MPH too high at 65MPH. I put 215 60 X16 on it and the speedo now agrees with my GPS.
