This answer was rated:

I am wondering if fitting 225 25 16 tyres instead of 225 60 16 will affect the computer of my 2012 Holden Commodore VE series 2.
JA: How old are the tires? And have they been a problem in the past?
Customer: The tyres are new dunlop
JA: Are you fixing your Commodore yourself? What have you tried so far?
Customer: no i do not do anything to the car myself it is always serviced and any problems a mechanic looks after it
JA: Anything else you want the mechanic to know before I connect you?
Customer: no

Hello I will help?

Is that 25 for the middle number (aspect ratio) correct?

If it is then yes the computer would not be happy with that change.

This is a 23% difference in size. The difference in circumfrence is almost 20 inches so the computer will not be happy.

Are you able to move up a couple of sizes in diameter? You would need new wheels.

Let me know so I can help
