i have 245/50R20 Tires, I now wish to purchase 245/45R20 tires, what are the downsides of having a 12.25 mm smaller tire? How do I get the correct speedometer reading?

you recalibrate the speedo

but with what though, do I have to go to the dealer? Do I have to buy the tires from them or will they charge me
any other thoughts

Buy a kit, remove cluster. Wire in calibration box. Install cluster.
Have a pro do it

Its a veeery small difference. Here are the speed readouts if 245/50/20 is on the left & is a 100% correct
the difference is so small like literally only a couple of mph
Not even enough to get your speedo recalibrated over. For all intensive purposes just treat your new reading as true
