Unless you're riding a bike equipped with a centerstand, getting a wheel off on the side of the road is going to be problematic. With help, it may be possible to rock the bike up on the kickstand and slide a block of wood under the frame or even hoist the thing onto a stump (don't laugh—I once saw four guys lift an Electra Glide onto a cement "mafia block" so they could pull the rear wheel). It may also be possible to borrow a small jack, which you could use in conjunction with the kickstand to hoist the bike high enough to remove the wheel. Either way, do give some forethought to what you'd do if a tire went flat out in the boonies. If that means stowing a can of aerosol flat fix on-board, do it. At the very least that should get you to the nearest gas station, where you can make arrangements for a proper repair.
