ok so i am like a bit heavy, 155 lbs. and i have an older racing bike. its a schwinn world bike. i replaced the tires/tubes and when i pump them up they only stay pumped for like a day and then they start to deflate. not majorly but when i get on the bike the tires look a little flat, again not completely flat. how do i fix them? i kno that there arent any holes in them. i already checked.
