I replaced a 700 x 35 mm semi-slick tires with a 700 x 38 mm treaded tires. They are huge; probably closer to 45 mm when figuring in the treads. They roll perfectly. I have some questions:

1. When I turn sharply it feels awkward. Is this dangerous in anyway? Or will I just get used to it?

2. Is there any chance of this tire popping off when I am riding?
