Traction Control and wheel changing

[Bellfour]

Hi all, after a bit of advice please?

 

My Z came with 20 inch wheels with 245's on the front and 275's on the back.  No problems other that a fairly stiff ride!!  

 

I swapped out these summer wheels for a stock set of touring 18's with 225/245 front and back respectively with winter tyres on for the winter.

 

I swapped these back to the 20' summers the other day and since then the Traction Control light comes on intermittently.  I'm confused as these are the same wheels and tyres that the car came with, which never had an issue.

 

I wasn't driving fast and this happened at below 30 mph on a straight dry road.

 

any advice would be greatly appreciated.

 

Paul

Sometimes it takes a few miles for the ECU to relearn.

Awesome, thanks.  I've not been too far (round block) due to lockdown.

 

Hopefully it will sort when things get back to normal(ish)!
