Need to re-cal speedo after bigger wheels?

Just moved to 18" wheels. 275-35 and 285-35 tires. Is there a need to re-calibrate the speedo? I'm not sure if its off or not but just figured I would ask.

I figured it would be something small like that. Good to know thanks.

Always a good excuse to pick up a handheld tuner as they can make such changes.
