My rear tyre on my hybrid is showing signs of wear . Just losing thread pattern so I have decided to swap it with the front tyre which still has a pretty good thread on in . I presume this is OK or am I missing something . I new to this maintence stuff . This is the first time I've had a tyre off in twenty plus years and it was harder than I remember but with much swearing and brute force and ignorance it got done . all good practice for when I need to do at the side of the road
