i was pumping my tire and the pump got stuck to the valve. while struggling to get the pump off of the valve, i pushed the valve into the wheel several times. then i pumped the tire and it rode just fine. this was for my front tire. do i need to worry about any possible damage to the tube? i don't want any surprises when i'm going down a hill at 20 mph and the front tube suddenly explodes. it's a hybrid bike with 700 x 35c tires (60-80 psi). thanks!
