I recently switched wheels and went to 18" from the stock 17" that came on the car.
Can I reclabrate the speedometer for the new wheels/tires with the Diablosport and if so how do I set it for the 235/50/18 that is now on the car??

On the Predator, go to performance tune/agree to disclaimer/choose tune/modify tune/modify parameters/ then you should see the setting in there for tire size adjustment.

It is also good to know the overall height or the tire/wheel combo from stock stock what you have. Most likely you changed profiles as well and normally in that case your overall height might have not changed thus not needing any modification.
