Wear and tear

I just started venturing into multiplayer a couple days ago. I’ve found that during the course of the race my cars will start to get loose as if I have excessive tire wear despite the wear and tear settings being set to cosmetic. Since it happens well after the tires have properly warmed up I thought maybe my tire/suspension were off however this doesn’t seem to happen when I’m in rivals or career mode were 10+ laps or not uncommon. Anyone else experience this?
