its pretty easy but 2 people helping you put it on makes it alot easier
anyway
spray the rim and tire with windex and/or dish soap
1 set tire down flat
2 set rim on top of tire
3. press to get one side of the rim in the tire
4. flip tire over
5. (this is where other ppl come in handy) slowly work way around tire pressing side into rim, having the others hold the tire as you work around so it wont pop back up
i did this with my rear tires, it took longer to take the old ones off then it did to put the new ones on
to take the old ones off, cut all the tire off that you can with a razor blade
get a flat head screw driver and slip it under the wires at the bead and pry upward to snap them
or, you can take it to a vehicle repair shop and most of them have tire changers
they charge like $10 or so for car tires anyways
hope this helps
