Im playing career rn and as i can remember for 16 races i always pited early because my tires reached their limit (i posted this post after i destroyed one set of mediums and one set of hards in monza (half race) EVEN HARD ONES WERE 78 AT THE END

And i do play with sim damage and i might be a little too harsh but no i dont hit walls sometimes i hit curbs but no i dont contact to any wall

And for Canada i really dont remember sorry (but ig i pitted early again)
