What Is the Difference Between 225/55R19 vs 225/65R17?
The primary difference between the 225/55R19 and 225/65R17 is the balance of wheel size and sidewall height. The 225/55R19 has a 22.50 mm (0.89") shorter sidewall, but its larger wheel results in a 5.80 mm (0.23") larger overall diameter and an 18.22 mm (0.72") larger circumference compared to the 225/65R17.
While both sizes have the same section width, the 17-inch setup uses a taller sidewall to offset its smaller wheel diameter.

Can I use 225/65R17 instead of 225/55R19?
No, you cannot use a 225/65R17 tire on a 19-inch wheel; the internal diameters must match perfectly. To use 225/65R17 size, you would need to switch to a 17-inch wheel set.
If you choose to make this wheel set change, the 225/65R17 will offer a more comfortable ride due to its taller sidewall (65 vs. 55 aspect ratio). Since the overall diameter difference is only 0.23 inches, your speedometer accuracy and safety systems will remain unaffected.
