Bigger tires comes issues

2016 Explorer XLT

I put some 20" tires on my buddies ride and he is reporting the Powertrain Malfunction Indicator has illuminated on the dash with the P160A DTC set. Is there anything beyond the tires in FORScan that I might need to change for to get the DTC to clear? What do I need to change to fix that?

From what size to what size did the tires change? I believe some Explorers have different pre-programmed compatible sizes that one can choose from. The general rule of thumb is that you should not exceed 3% of the OEM tire's diameter.

I increased it to the sport tires from the XLT tires. I think I did 255/50/18s on them.
