Re: First build by most not handy guy
Bike shops sell plastic tire tools with smooth edges. Like the man said; Don't use a screwdriver or anything sharp. You'll puncture the tube and scratch up the rim. If you can do it by hand, that's the best/safest way. To be sure the tube is completely deflated, remove the valve stem core.
