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.
