Can I use 275/50R22 instead of 275/45R22?
Yes, you can switch to 275/50R22 from 275/45R22 if your vehicle has enough clearance for the ≈1.08" increase in overall diameter and the ≈14 mm taller sidewall. The handling will feel slightly softer, and the speedometer will read about 3.4% slow. Because the overall diameter difference is above the commonly recommended ±3% tolerance, you should check your vehicle manufacturer’s fitment guidelines. A larger deviation may affect ABS, traction control, speedometer accuracy, and warranty compliance.
What Is the Difference Between 275/45R22 vs 275/55R20 Tire Sizes?
The differences between 275/45R22 and 275/55R20 include rim diameter and sidewall height. The 275/45R22 fits a 22-inch wheel, while the 275/55R20 fits a 20-inch wheel. Because the 20-inch rim is smaller, the sidewall of the 275/55R20 is taller at 151.25 mm (≈ 151.3 mm) compared to 123.75 mm (≈ 123.8 mm) on the 275/45R22.
However, the overall diameters of the two sizes are very close:
- 275/45R22: 806.30 mm (≈ 31.75")
- 275/55R20: 810.50 mm (≈ 31.90")
This means the 275/55R20 is only 4.20 mm (≈ 0.17") taller, a difference of just ≈ 0.5%, which is well within acceptable fitment tolerances.

Can I use 275/55R20 instead of 275/45R22?
No, you cannot use 275/55R20 tires as a direct replacement for 275/45R22 if your vehicle currently has 22-inch wheels. The 275/55R20 tire is designed for a 20-inch rim and cannot be mounted on a 22-inch rim under any circumstances because the bead seat diameter is physically incompatible. To use 275/55R20 tires, you must purchase a complete set of 20-inch wheels. Once the correct 20-inch wheels are installed, the overall diameter difference is only about 0.5%, so the size is compatible and provides a noticeably smoother, more cushioned ride due to the taller sidewall.
