I'm about ready to change the tires on my bike after 12,000 miles. So I've been looking at my book on how to do so. It says you need to either remove the rear fender (not looking forward to doing) or lift the bike high enough to get the tire out from under the bike. I like the latter better. But how high is it going to have to be? I dont think a motorcycle jack alone will do this but i have not tried yet. Could somone give some advice on how they do it please.
