For two kids you will want pneumatic tires. Since you use a car I would suggest the babyjogger city mini gt which has an easy fold. Strollers are perfect to buy from craigslist as Americans don't use them much outside the mall. Baby gizmo has video reviews so you can compare. Never get a long stroller, like pp they are difficult to leverage and not safe, imagine crossing a street with shrubbery, cars don't look down so if they can't see you your stroller is vulnerable.
