I hope this isn't a stupid noob question.....but, I've read that pit stops for tire changes don't start until around level 23. My question is.....if I equip my cars (such as my 458 Italia or my ZR-1) with racing soft tires now (I'm only level 14 A-Spec), are there any disadvantages such as my tires being so soft that they'll wear down and harm performance before I even finish a race? I don't want to be running in a 10 or 15 lap race and have my soft tires screw up my race because I can't pit to change them. Or......is tire wear simply not an issue whatsoever until level 23?
