Tires for track day
I will be in a track day here in South America on Monday and did not want to use the "normal" tires that came with the car 265-35-19, being the car 1 month old.
Instead I have an extra set of 245-35-19 (same as front tires) and was wondering what would happen to the car if I put these tires in the back, so I would have 4 tires same size: 245-35-19...
Can I damage the car?
Do I need to do something to the DTM button in the center console?
Excuse my "beginner" question, but I am sure you know more than I do.
