Calibrating you speedometer

Does anyone know what size tire that I will have to calibrate my speedometer due to bigger tires?

And also do I need to change out my breaks if I put bigger tires on?

Quadratec has a chart based on gear ratio / tire size to select the proper speedo gear when bumping up tires and/or ring & pinion.

Your factory brakes should be fine.

Depending on how much wider you go, backspacing on the factory rim may be an issue causing rub during a tight turn. You may need wheel spacers, or get rims with less backspace (negative offset), to push the tires out, away from the fender wells.
Happy Trails!
