Alternate Tire Size

Thinking of switching from 20” rims to 18” rims. What tire size would be equal to my current 275/55/20?? So that my speedometer is still accurate. What are my options? Thanks.

Use this tool:

Do the comparison tool.

You'll notice the truck will ride nicer on smaller rims with more rubber.

275/65 R18 is also a good diameter match, but 265/60 R18 is not. That would require reprogramming.
