Comparison of 265/50R20 With Similar Tire Sizes
Comparing 265/50R20 with 255/55R20 and 265/55R20 shows how changes in width and aspect ratio impact overall diameter, ride height, and whether a swap stays within common tolerance ranges.
What Is the Difference Between 265/50R20 vs 255/55R20?
The main differences between 265/50R20 and 255/55R20 are the section width and aspect ratio. Both fit 20-inch wheels, but the 255/55R20 has a taller sidewall and a larger overall diameter.
The 265/50R20 sidewall height: 132.50 mm (≈ 5.217"); overall diameter: 773.0 mm (≈ 30.433"). For the 255/55R20 size, the sidewall height is: 140.25 mm (≈ 5.522"); the overall diameter: 788.5 mm (≈ 31.043")
This means 255/55R20 is 10 mm narrower, has a 7.75 mm (≈ 0.305") taller sidewall, and is 15.5 mm (≈ 0.610") larger overall.

Can I use 255/55R20 instead of 265/50R20?
Yes, in many cases. The overall diameter increase of ≈ 2.01% is typically within common tolerance, so this swap is often workable on vehicles that have enough clearance. Your speedometer would read slightly slow (when it shows 60 mph, actual speed would be about 61.2 mph), and the vehicle would sit about 0.305" higher due to the larger radius. Because the 255/55R20 has a 0.3" taller sidewall, it will likely provide a slightly softer ride and better protection against potholes compared to the 265/50R20; confirm there’s no rubbing at full steering lock and suspension compression, and make sure the load index meets your vehicle’s requirements (if, for example, the original 265 tire was 107 load index, the new 255/55R20 one should be 107 or 110).

Can I use 265/55R20 instead of 265/50R20?
It’s a marginal swap, not an ideal one.
The overall diameter increase of ≈ 3.43% is slightly above the commonly referenced ±3% guideline, placing this change in the borderline range. Your speedometer would read slow (when it shows 60 mph, the actual speed would be about 62.1 mph). The vehicle would sit about 0.522" higher. This can also affect ABS/traction-control calibration and clearance in tighter wheel wells. Hence, it’s a “check carefully first” situation rather than a straightforward replacement.
Because the width is the same, you won't have new issues with the tire hitting the suspension (struts), but you might experience "rubbing" against the plastic inner fender liners when the steering wheel is turned to full lock. Another concern is that a larger 265/55R20 diameter tire acts like a taller gear. It requires slightly more braking force to stop and slightly more engine torque to get moving. On a powerful vehicle, this is barely noticeable; on a smaller engine, it can feel "sluggish."
