Does Larger Rims/Tires Mean re-do my ECU????

I thought maybe, but what is the consensus?

It may mean a welcome trip to Maryland for Oliver to re-tune my 500 on the DYNO.....

 

if you go larger rim, but smaller tire height = no need to re-dyno....if its within specs...

17s with 45 series tires is almost like 19s with 30 series tires.

 

I have definitely lost power.......When I drill the pedal to the floor my 500 just screeches the tires. Before the new rims and tires, I could smoke the tires with no problem.
Think an ECU re-tune could give me back anything?
